Yellow house bats (Scotophilus) have been known for centuries as a widespread genus of vesper bats in the Indomalayan Region. Despite this, their taxonomic status and phylogeographical patterns remain unclear due to differing criteria employed by early taxonomists and inconsistencies between morphological and molecular assessments. To address these issues, we undertook a comparative phylogeographic analysis of Asian Scotophilus spp. using integrated genetic and morphological analyses of samples collected across the region. These demonstrate that yellow house bats in Asia can be classified into just two widespread species, namely the smaller S. kuhlii (e.g., FA ≤ 53.1 mm, GLS ≤ 20.18 mm) and the larger S. heathii (e.g., FA ≥ 53.4 mm, GLS ≥ 20.85 mm), which occur in sympatry in different parts of the Indomalayan Region. Although these two sympatric species share similar eco‐ethological preferences, they differ considerably in their geographic distributions and intraspecific variation in mtDNA sequences and morphological traits. These disparities were likely misinterpreted as indicating potential cryptic diversity in previous studies, whereas we suggest they are related to interspecific differences in sex‐biased gene flow and phenotypic plasticity to adapt to varying environments. Our study highlights the importance of using multiple datasets to resolve taxonomic uncertainties and reconstruct demographic and phylogeographic histories of sympatric species.

- Abstract
The species delimitations species of Scotophilus from the of Afro-Malagasy Region remain unresolved. One of the most problematic named taxa is S. borbonicus, which was described based on specimens reputed to be from La Réunion Island, western Indian Ocean. Only one of two specimens mentioned in the description of S. borbonicus sensu stricto has been located in a museum collection and after considerable recent fieldwork on La Réunion, no Scotophilus has been captured. Given that the name borbonicus has priority over other named small Afro-Malagasy forms, this has led to considerable taxonomic ambiguity. We report here on a short mitochondrial sequence from the lectotype of S. borbonicus, which is nested within individuals of S. trujilloi captured in Kenya and Tanzania. These results are best interpreted as the lectotype of S. borbonicus was not obtained on La Réunion but along the eastern coast of Africa. We propose that the best means to resolve potential taxonomic problems, particularly concerning future research on small Afro-Malagasy members of the genus, is to consider the name S. borbonicus a nomen dubium. If indeed individuals of this genus are captured on La Réunion in the future and molecular data obtained, the species in question may be new to science and in need of formal description.

Parasites of the haemosporidian genus Polychromophilus have exclusively been described in bats. These parasites belong to the diverse group of malaria parasites, and Polychromophilus presents the only haemosporidian taxon that infects mammalian hosts in tropical as well as in temperate climate zones. This study provides the first information of Polychromophilus parasites in the lesser Asiatic yellow bat (Scotophilus kuhlii) in Thailand, a common vespertilionid bat species distributed in South and Southeast Asia. The gametocyte blood stages of the parasites could not be assigned to a described morphospecies and molecular analysis revealed that these parasites might represent a distinct Polychromophilus species. In contrast to Plasmodium species, Polychromophilus parasites do not multiply in red blood cells and, thus, do not cause the clinical symptoms of malaria. Parasitological and molecular investigation of haemosporidian parasites of wildlife, such as the neglected genus Polychromophilus, will contribute to a better understanding of the evolution of malaria parasites.

BATS as carriers of disease , *ZOONOSES , *SCOTOPHILUS , *ASTROVIRUSES , *BIODIVERSITY - Abstract
Environmental modifications are leading to biodiversity changes, loss and habitat disturbance. This in turn increases contacts between wildlife and hence the risk of transmission and emergence of zoonotic diseases. We analyzed the environment and land use using remote spatial data around the sampling locations of bats positive for coronavirus (21 sites) and astrovirus (11 sites) collected in 43 sites. A clear association between viruses and hosts was observed. Viruses associated to synanthropic bat genera, such as Myotis or Scotophilus were associated to highly transformed habitats with human presence while viruses associated to fruit bat genera were correlated with natural environments with dense forest, grassland areas and regions of high elevation. In particular, group C betacoronavirus were associated with mosaic habitats found in anthropized environments. [ABSTRACT FROM AUTHOR]

Evolutionary parallelism complicates taxonomy of the bat genus Scotophilus. This implies the necessity for a careful examination of morphologically similar species. Robbins’ – or “nutlet” – house bat Scotophilus nucella is an insufficiently known taxon of the African rainforest zone based on just a handful of recorded specimens previously included in the nut-coloured house bat S. nux. Because its phylogenetic relationship to S. nux and other congeneric species is unknown, it was assessed using analysis of DNA sequences of single mitochondrial and nuclear genes. Based on the mitochondrial cytochrome b sequences, S. nucella was placed in sister position to S. nux. A genetic divergence of 7.8-9.4 % between them supports the recognition of S. nucella as a distinct species. Analysis of partial sequences of the nuclear zinc finger protein gene on the Y-chromosome corroborated the sister relationship of S. nucella and S. nux, while showing sufficient differences to consider them as two species. Mitochondrial genetic diversity in S. nucella was low, whereas S. nux showed a rather complex genetic structure over a large geographic area, despite limited sampling. The origin of the forest group of Scotophilus could be dated to the Miocene-Pliocene transition and the split leading to the contemporary species S. nucella and S. nux to the Pliocene-Pleistocene transition. Both time periods are characterized by an arid climate that led to the retreat of forest environment, which likely promoted speciation in forest refugia. Mid-Pleistocene diversification in S. nux led to a separate lineage from Guinea, West Africa, for which a subspecific status may be considered, as it differs 3.4-4.5 % from other African populations.

BATS ,SCOTOPHILUS - Abstract
Occurrence of Scotophilus kuhlii was speculated throughout the southern plain (Tarai) of Nepal. However, there was no record of voucher specimen of the species from Nepal. We collected a specimen from the Tikulia tole, Pakali Village Development Committee, Sunsari District of southeastern Nepal and deposited at Central Department of Zoology (CDZ) Museum, Tribhuvan University, Kathmandu. The specimen was identified as S. kuhlii based on measurement of external body, cranial, dental parts and detail description of the species. This is the first specific locality record of the species from Nepal that confirms its presence in the country. [ABSTRACT FROM AUTHOR]

Scotophilus livingstonii Brooks & Bickham, 2014 Scotophilus livingstonii Brooks & Bickham, 2014: 11. COMMON NAME. — Livingstone’s House Bat. MATERIAL EXAMINED. — Agumatsa (Wli Waterfall) • 1 ♀; SMF 92137; caught on 11.VIII.2001. REMARK Originally identified as Scotophilus dinganii (A. Smith, 1833) due to its bright yellow ventral side side and its forearm length of 57.8 mm, the West African form, which also occurs in western Kenya, has been recently renamed S. livingstonii based on phylogenetic and morphological distinct S. dinganii -like clades (Brooks & Bickham 2014). Our specimen was caught in a net set across the Agumatsa River flanked by secondary forest and nearby small cassava fields. Other Ghana-Togo Highlands specimens are known from Odomi Jongo, 12 Miles E Nkwanta in Ghana (USNM 424888) and from Atakpamé and Ezimé in Togo (Robbins 1980; Robbins et al. 1985). The species was also caught at three locations on the Accra Plains (Decher 1997a and USNM, as S. dinganii) and seems to be most commonly associated with Guinea savanna, forest savanna mosaic, and high forest edge. Records from Côte d’Ivoire are all from the northern tree savanna (Fahr 1996, as S. dinganii). This species also seems to adapt to rooftops and thatched huts for its roosts. CONSERVATION STATUS. — The conservation classification of S. livingstonii on the IUCN Red List is “Least Concern”.

The giant house bat Scotophilus nigrita, one of the largest vespertilioniform bat species in the world, is a poorly known taxon, especially with respect to its phylogenetic relationships to congeneric species. Its phylogenetic position was thus assessed by analysing DNA sequences of single mitochondrial and nuclear genes. Based on the mitochondrial cytochrome b, S. nigrita was found to be paraphyletic with respect to continental African species S. colias, S. dinganii, S. nigritellus and S. viridis. Analysis of sequences of the nuclear zinc finger protein gene on the Y chromosome corroborated the general pattern of the cytochrome b phylogeny, although phylogenetic relationships were poorly resolved. These results clearly contradict the published data on S. nigrita from Kenya for both markers, rendering the hypothesis of historical hybridization with S. colias implausible and questioning the taxonomic affiliation of the particular Kenyan sequence. A deep split in the cytochrome b phylogeny between S. nigrita from West and Southern Africa reached sequence divergence values of 7.6% to 8.1%, a finding that supports taxonomic elevation of the two currently recognized subspecies into separate species S. nigrita and S. alvenslebeni.

- Abstract
Based on niche theory, closely related and morphologically similar species are not predicted to coexist due to overlap in resource and habitat use. Local assemblages of bats often contain cryptic taxa, which co-occur despite notable similarities in morphology and ecology. We measured in two different habitat types on Madagascar levels of stable carbon and nitrogen isotopes in hair (n = 103) and faeces (n = 57) of cryptic Vespertilionidae taxa to indirectly examine whether fine-grained trophic niche differentiation explains their coexistence. In the dry deciduous forest (Kirindy), six sympatric species ranged over 6.0‰ in δ15N, i.e. two trophic levels, and 4.2‰ in δ13C with a community mean of 11.3‰ in δ15N and −21.0‰ in δ13C. In the mesic forest (Antsahabe), three sympatric species ranged over one trophic level (δ15N: 2.4‰, δ13C: 1.0‰) with a community mean of 8.0‰ δ15N and −21.7‰ in δ13C. Multivariate analyses and residual permutation of Euclidian distances in δ13C–δ15N bi-plots revealed in both communities distinct stable isotope signatures and species separation for the hair samples among coexisting Vespertilionidae. Intraspecific variation in faecal and hair stable isotopes did not indicate that seasonal migration might relax competition and thereby facilitate the local co-occurrence of sympatric taxa.

Background Numerous studies have been undertaken to advance knowledge of apicomplexan parasites infecting vertebrates, including humans. Of these parasites, the genus Plasmodium has been most extensively studied because of the socio-economic and public health impacts of malaria. In non-human vertebrates, studies on malaria or malaria-like parasite groups have been conducted but information is far from complete. In Madagascar, recent studies on bat blood parasites indicate that three chiropteran families (Miniopteridae, Rhinonycteridae, and Vespertilionidae) are infected by the genus Polychromophilus with pronounced host specificity: Miniopterus spp. (Miniopteridae) harbour Polychromophilus melanipherus and Myotis goudoti (Vespertilionidae) is infected by Polychromophilus murinus. However, most of the individuals analysed in previous studies were sampled on the western and central portions of the island. The aims of this study are (1) to add new information on bat blood parasites in eastern Madagascar, and (2) to highlight biotic and abiotic variables driving prevalence across the island. Methods Fieldworks were undertaken from 2014 to 2016 in four sites in the eastern portion of Madagascar to capture bats and collect biological samples. Morphological and molecular techniques were used to identify the presence of haemosporidian parasites. Further, a MaxEnt modelling was undertaken using data from Polychromophilus melanipherus to identify variables influencing the presence of this parasite Results In total, 222 individual bats belonging to 17 species and seven families were analysed. Polychromophilus infections were identified in two families: Miniopteridae and Vespertilionidae. Molecular data showed that Polychromophilus spp. parasitizing Malagasy bats form a monophyletic group composed of three distinct clades displaying marked host specificity. In addition to P. melanipherus and P. murinus, hosted by Miniopterus spp. and Myotis goudoti, respectively, a novel Polychromophilus lineage was identified from a single individual of Scotophilus robustus. Based on the present study and the literature, different biotic and abiotic factors are shown to influence Polychromophilus infection in bats, which are correlated based on MaxEnt modelling. Conclusions The present study improves current knowledge on Polychromophilus blood parasites infecting Malagasy bats and confirms the existence of a novel Polychromophilus lineage in Scotophilus bats. Additional studies are needed to obtain additional material of this novel lineage to resolve its taxonomic relationship with known members of the genus. Further, the transmission mode of Polychromophilus in bats as well as its potential effect on bat populations should be investigated to complement the results provided by MaxEnt modelling and eventually provide a comprehensive picture of the biology of host-parasite interactions.

BATS ,SCOTOPHILUS ,VESPERTILIONIDAE ,MAMMALS - Abstract
In order to provide basic data on bat species of the Far North Region of Cameroon – the northernmost constituent province of the Republic of Cameroon – a survey was carried out between the months of January and March 2011. Mist nets set at ground level were used over a 22-night period covering nine sites, from which a total of 413 individuals belonging to 18 species, nine genera and three families were captured. Insectivorous bats presented a wide specific diversity (15 species) and a wide relative abundance, while frugivorous bats were far less (three species).Scotophilus dinganii(n= 227) was the most commonly recorded species at the study site. The sample efficiency was estimated at 77.5% with a species accumulation curve not reaching an asymptote, suggesting that the survey did not record all species present. During this study, two species were recorded for the first time in Cameroon:Mops niveiventerandChaerephon chapini. [ABSTRACT FROM AUTHOR]

The species delimitations species of Scotophilus from the of Afro-Malagasy Region remain unresolved. One of the most problematic named taxa is S. borbonicus, which was described based on specimens reputed to be from La Reunion Island, western Indian Ocean. Only one of two specimens mentioned in the description of S. borbonicus sensu stricto has been located in a museum collection and after considerable recent fieldwork on La Reunion, no Scotophilus has been captured. Given that the name borbonicus has priority over other named small Afro-Malagasy forms, this has led to considerable taxonomic ambiguity. We report here on a short mitochondrial sequence from the lectotype of S. borbonicus, which is nested within individuals of S. trujilloi captured in Kenya and Tanzania. These results are best interpreted as the lectotype of S. borbonicus was not obtained on La Reunion but along the eastern coast of Africa. We propose that the best means to resolve potential taxonomic problems, particularly concerning future research on small Afro-Malagasy members of the genus, is to consider the name S. borbonicus a nomen dubium. If indeed individuals of this genus are captured on La Reunion in the future and molecular data obtained, the species in question may be new to science and in need of formal description.

This data article informs about Chiropteran diversity, new records, ecosystem services and possible pathogen carriers in fragmented forests (sub-divided by utility corridors, man-made structures, untouched and secondary plantations) within districts Setiu (Setiu Research Station), Hulu Terengganu (Saok and Lasir waterfalls) and Besut (Gunung Tebu Forest Reserve) of state Terengganu, Peninsular Malaysia. These bats were captured using harp traps and mist nets that were set 10 m apart across flyways, streams and less cluttered trees in the 50 m × 50 m transect zones (identified at each site). All animals were distinguished by morphology and gender before their release at the site of capture. The data comprise of five bat family groups Hipposideridae, Megadermatidae, Pteropodidae, Rhinolophidae and Vespertilionidae. It is interesting to note that untouched Saok Waterfalls is home to wide variety of bats listed (68.8%), followed by secondary forests of Gunung Tebu Forest Reserve (24.8%), untouched Lasir Waterfalls (4.8%) and lastly, Setiu Research Station as least favored (1.6%). Chiroptera like Cynopterus brachyotis ( n = 23, 37.7%), Hipposideros bicolor ( n = 6, 9.8%) and Scotophilus kuhli ( n = 6, 9.8%) were most dominant in the checklist whereas Hipposideros armiger , Murina suilla and Scotophilus kuhlii are new data records in the fragmented forests of Terengganu. The data were interpret into Shannon, Simpson, Margalef, Menhinik and Evenness indices to individually or collectively distinguish chiropteran variety in Terengganu State whereas weight-forearm length (W/FA) informs about chiropteran Body Condition Index (-0.25 to 0.25). The function of bats were also identified to distinguish service providers (pollination and forests regeneration) and zoonotic pathogen carriers (in particular to Leptospira bacteria, Nipah virus and Sindbis virus).

Environmental modifications are leading to biodiversity changes, loss and habitat disturbance. This in turn increases contacts between wildlife and hence the risk of transmission and emergence of zoonotic diseases. We analyzed the environment and land use using remote spatial data around the sampling locations of bats positive for coronavirus (21 sites) and astrovirus (11 sites) collected in 43 sites. A clear association between viruses and hosts was observed. Viruses associated to synanthropic bat genera, such as Myotis or Scotophilus were associated to highly transformed habitats with human presence while viruses associated to fruit bat genera were correlated with natural environments with dense forest, grassland areas and regions of high elevation. In particular, group C betacoronavirus were associated with mosaic habitats found in anthropized environments., Graphical abstract Image 1, Highlights • Deforestation and anthropization generate high diversity of bats. • Anthropized environment increases the risk of bat-borne virus transmission. • Highly pathogenic αCoV_2 & βCoV_C are linked to anthropogenic habitat. • Murine astroviruses are associated with human settlements. • Ungulates astroviruses are associated with wild areas (elevated grasslands).

Twenty-four scincid lizards (spotted forest skink, Sphenomorphus scotophilus) from Peninsular Malaysia were examined for gastrointestinal helminths. Six species of Nematoda, mature individuals of Bakeria schadi, Meteterakis singaporensis, Parapharyngodon maplestoni, Physalopteroides grismeri, and Spinicauda sp., and larvae of Acuariidae gen. sp. were found. Bakeria schadi had the largest number of individuals (38) and the highest prevalence (48%). Larvae of Acuariidae had the greatest mean intensity (6.5 ± 6.4 SD). All represent new host records for S. scotopilus. Our findings indicate that Sphenomorphus scotophilus is parasitized by generalist helminths that also infect other lizards.

Roost use by African bats is poorly known, particularly for those using cavities in trees. Two sympatric species of Scotophilus were fitted with transmitters and tracked to their respective roosts in a natural savanna site in Swaziland. Both species roosted exclusively in trees, apparently preferring Combretum imberbe trees with large girths. The conservation of such roosting trees may be critical to the continued persistence of cavity-nesting insectivorous bats in African savannas. [ABSTRACT FROM AUTHOR]

Ecomorphological studies reveal the coexistence of many phenotypically similar bat species. If competition theory is correct, these species should occupy different niches. Here we investigate whether 2 sympatric sibling species of insectivorous bats, Scotophilus dinganii and Scotophilus mhlanganii, that are similar in morphology also occupy similar niches as predicted by the ecomorphological paradigm. The only phenotypic differences we found between the 2 species were a 10-kHz difference in their echolocation frequencies (S. mhlanganii 42.6 ± 1.6 kHz; S. dinganii 33.7 0 ± 1.8 kHz) and a higher wing loading in S. mhlanganii (15.5 ± 2.3 N/m²) compared to S. dinganii (13.6 ± 1.5 N/m²) as a result of the former's similar mass but shorter wingspan. However, there was much overlap in the wing parameters, including wing loading, of the 2 species. In support of the ecomorphological paradigm, the similarity in their phenotypes was reflected in the absence of any detectable spatial or temporal differences in their habitat use (determined by radiotelemetry). Furthermore, subtle differences in skull morphology were correlated with subtle differences in the size of dietary items eaten. S. dinganii, with its larger skull, ate a wider range of insect prey sizes (11.2-18.9 mm) than S. mhlanganii (11.6-12.2 mm). The most profound ecological difference between the 2 species was the use of different roosts. S. dinganii always was found in building roosts and S. mhlanganii always in trees. Thus, the ecological similarities with their phenotypic correlates support the ecomorphological paradigm. Assortative mating, resulting from the use of different roosts, combined with genetic drift, may explain the subtle differences reported here. [ABSTRACT FROM AUTHOR]

SCOTOPHILUS , *ZOOGEOGRAPHY , *PHYLOGENY , *DNA , *GENETICS - Abstract
The genus Scotophilus is composed of 15 recognized species with 7 species distributed throughout sub-Saharan Africa, 4 distributed across southern and southeastern Asia, 3 endemic to Madagascar, and 1 endemic to Reunion Island. Scotophilus is plagued with problems in species definition, and systematic relationships among members of the genus are poorly understood. We used mitochondrial DNA (mtDNA) and Y-chromosome sequence data from 11 of the 15 recognized species, which represent the most comprehensive taxonomic coverage to date, to examine phylogenetic patterns within Scotophilus. All trees have S. kuhlii from Asia as the most basal species followed by S. nux from Africa. However, S. heathii from Asia is embedded within the other African Scotophilus, indicating a complex biogeography with multiple continental exchanges. Furthermore, the Malagasy taxa are most closely related to 2 different African species, suggesting independent colonizations of Madagascar from the continental mainland. In addition, African S. dinganii did not comprise a monophyletic group but exhibited at least 2 additional cryptic species based on high levels of genetic divergence in the cyotchrome-b gene. The large-bodied S. nigrita is closely related to S. dinganii with a similar mtDNA haplotype but distinct zfy haplotype, suggesting a possible hybridization event in the most recent common ancestor that potentially represents a mitochondrial capture. Overall measures of interspecific genetic distances ranged from 4.2% to 19.2% for mtDNA data and 0.18% to 2.14% for Y-chromosome data, indicating that members of the genus Scotophilus are highly divergent from one another.

Karyotype descriptions are given for Scotophilus dinganii (2n = 36, FNa = 50) and a recently discovered sister-species, Scotophilus sp. nov. (2n = 36, FNa = 52). These two sibling species occur sympatrically and are distinguished by body size, echolocation frequency and cytochrome b sequence. Cytogenetically, both species differ from other Scotophilus species in the subtelocentric morphology of chromosome 2 and a terminal heterochromatic segment on the X chromosome. Further, Scotophilus sp. nov. is characterized by a subtelocentric chromosome 4 not found in any other Scotophilus species. Comparing the Scotophilus karyotype with that of the vespertilionid genus Myotis, extensive conservation of whole chromosome arms has been found recently. However, out of 25 chromosomal arms six could not be identified in Scotophilus. Therefore, in the present study fluorescence in situ hybridization with whole chromosome painting probes from Myotis myotis was carried out on metaphase preparations from Scotophilus dinganii and Scotophilus sp. nov. These experiments revealed that three previously unidentified Scotophilus chromosomes (A, B, C) contain homologous sequences to Myotis chromosomes 18 plus 22, 19 plus 25, and 16/17, respectively.

Little is known about the thermal regulatory behaviour of free-ranging subtropical bats. We studied torpor use in two free-ranging subtropical sibling species of insectivorous bat, Scotophilus dinganii (A. Smith, 1833) and Scotophilus mhlanganii, during the austral autumn. All S. dinganii (mass 28.9 ± 2.6 g (mean ± SD)) roosted in buildings, whereas all S. mhlanganii (28.0 ± 0.4 g) roosted in the foliage of trees or in a tree cavity. Contrary to what has been seen in other subtropical species, both Scotophilus species used only one bout of torpor per day. Bats entered torpor 2 h after returning from foraging and aroused passively as the roost was heated by the sun the following day. There was a negative correlation between duration of foraging and duration of torpor, probably because bats that foraged longer had less time for torpor. Despite physical differences between roosts, foliage and building roosts appeared equally thermally labile, resulting in torpor bouts of similar depth and duration between individuals of the two species that used such roosts. Cavity-roosting female S. mhlanganii, on the other hand, used torpor bouts that were longer and shallower than those used by its female conspecifics in foliage roosts and female S. dinganii in buildings. Thus, thermal regulatory behaviour was determined more by the type of roost used than by interspecific differences in physiology. [ABSTRACT FROM AUTHOR]

Early embryonic development and implantation were studied in one of the Indian tropical bat Scotophilus heathi. This species is selected from its previous reports for an alternate animal model to study the reproduction in mammals. This bat is monoestrus. It also exhibits differential growth of embryos and generally one implantation per uterine horn. Embryo development was studied with dated pregnant females bred in captivity. Scotophilus heathi is an induced ovulator requiring several matings for ovulation to occur. In captivity, generally, it ovulates a single ovum after the third mating in captivity. The second ovulation occurs either at the fourth or fifth matings in the case when first ovulation occurs at the third mating. In our experiment, 70% of the bat ovulated both the ova simultaneously either at the fourth or fifth mating. The females that showed differential ovulation also showed differential embryonic development and differential implantation. The embryos could not begin compaction during cleavage and went to a state of block for about 8–10 days at the 6–8-cell stage. This block was found to be related to the formation of corpora lutea. Culmination of block coincides with the presence of progesterone in serum. Then, the developmental block is removed and embryos resume development. The total preimplantation period of development takes 20–22 days including the block period. This study reports that bat embryonic development can be studied like in other laboratory animals. It may also provide another model to study developmental block. [ABSTRACT FROM AUTHOR]

Abstract: The ovulation induction property of ICI 182,780 a pure antiestrogen and enclomiphene citrate (ENC) was carried out in Scotophilus heathi, an Indian tropical vespertillionid bat, during December to February i.e., preovulatory period. This bat ovulates two ova naturally and shows ovulatory asynchrony. The study showed that 100 ìg of ENC followed by 10 IU hCG resulted in significantly lower number of ovulation. Whereas, the pure antiestrogen ICI 182,780 at a dose of 100 ìg followed by 10 IU hCG resulted in ovulation induction (4.2±0.4), which is significantly different in comparison to other groups. This is possibly the first report of ovulation induction using this pure antiestrogen i.e., ICI 182,780 in any bat as well as in any animal model that exhibits temporary anovulation similar to polycystic ovary disease (PCOD). This antiestrogen may be useful to induce ovulation in PCOD patients. [Copyright &y& Elsevier]

The African yellow house bat, Scotophilus dinganii, was found to be seasonally monestrus, carrying a single foetus in each of the two uterine horns of the bicornuate uterus. Implantation was superficial, with amniogenesis initiated early during embryogenesis. The amnion in S. dinganii was a schizamnion, and it is deduced that its formation was preceded by cavitation of the inner cell mass, with formation of the definitive amniotic cavity, where the floor of the cavity eventually formed the embryonic disc and its roof the ectodermal part of the true or definitive amnion.

Abstract: Scotophilus heathi is a seasonally monoestrous subtropical vespertilionid bat found at Varanasi, India. Although the antral follicles remain present in the ovaries of S. heathi from November till March, ovulation is delayed in this species until early March. In order to understand the mechanism of ovulation suppression during this period of delayed ovulation, the effects of human chorionic gonadotropin (hCG), pregnant mare''s serum gonadotropin (PMSG), follicle stimulating hormone (FSH) and gonadotropin releasing hormone agonist (GnRH agonist) on ovarian morphology and steroid concentration were investigated. Hormonal treatments were given as a single i.p. dose 24h after capture. The bats were sacrificed 48h after the injection. Treatment with hCG, PMSG, FSH and GnRH agonist failed to induce ovulation in S. heathi, although these hormones produced a high degree of ovarian stimulation. The administration of hCG and PMSG induced ovarian enlargement, intense hyperemia, marked changes in the interstitial cells (ICs), development of several antral follicles and a varying degree of abnormalities in the oocytes of most of the antral follicles. In the bats treated with hCG, PMSG and GnRH agonist, androstenedione concentration increased significantly to extraordinarily high levels, whereas estradiol concentration decreased. Administration of FSH caused regression of ICs and pyknosis of granulosa cells in the majority of antral follicles. FSH did not enhance androstenedione concentration. The results of the present study suggest that the failure of hormonal treatments to induce ovulation during the period of delayed ovulation might be due to a seasonal desensitization of ovarian follicles in S. heathi. The hormonal treatment instead stimulated the ICs to produce a high level of androstenedione resulting in atretic changes of the antral follicles. [Copyright &y& Elsevier]

We conducted a survey in Cambodia in 2000 on henipavirus infection among several bat species, including flying foxes, and persons exposed to these animals. Among 1,072 bat serum samples tested by enzyme-linked immunosorbent assay, antibodies reactive to Nipah virus (NiV) antigen were detected only in Pteropus lylei species; Cynopterus sphinx, Hipposideros larvatus, Scotophilus kuhlii, Chaerephon plicata, Taphozous melanopogon, and T. theobaldi species were negative. Seroneutralization applied on a subset of 156 serum samples confirmed these results. None of the 8 human serum samples was NiV seropositive with the seroneutralization test. One virus isolate exhibiting cytopathic effect with syncytia was obtained from 769 urine samples collected at roosts of P. lylei specimens. Partial molecular characterization of this isolate demonstrated that it was closely related to NiV. These results strengthen the hypothesis that flying foxes could be the natural host of NiV. Surveillance of human cases should be implemented. [ABSTRACT FROM AUTHOR]

Ovarian proteins synthesized de novo and secreted in vitro were investigated during different stages of the reproductive cycle of Scotophilus heathi . We found increased ovarian protein synthesis and secretion during the recrudescence and the preovulatory periods, coinciding with two peaks of follicular development and steroidogenesis. The ovaries synthesized protein at a low rate during quiescence and the late phase of delayed ovulation. In vitro analysis using 35 S-methionine incorporation showed increased synthesis of 66 kDa protein during delayed ovulation, but secretion of this protein declined markedly during the preovulatory period. N-terminal sequencing of the 66 kDa protein showed that it shares 70% homology with human serum albumin. Immunocytochemistry indicated that this protein is found primarily in the granulosa cells of the follicles. Whether the increase in albumin production by the ovaries during delayed ovulation is associated with a hyperinsulinemic and hyperandrogenic condition requires further investigation.

The aim of this article was to evaluate the physiological significance of tumor necrosis factor-α (TNF-α) in seasonal accummulation of adipose tissue, hyperinsulinemia, and anovulation in Scotophilus heathi. The result showed seasonal variations in the circulating TNF-α level. A higher level of circulating TNF-α was observed during quiescence and recrudescence, whereas a lower level of TNF-α was observed during winter dormancy and the preovulatory period. An increased circulating TNF-α level coincided closely with accumulation of adipose tissue and hyperinsulinemia. Immunocytochemical localization of TNF-α in the ovary showed immunoreactivity mainly in the oocytes and theca-interstitial cells. The oocytes of small and medium-sized follicles showed strong TNF-α immunostaining, whereas weak immunoreactivity was observed in the large antral follicles. The atretic follicles showed mild TNF-α immuno-staining. TNF-α immunoreactivity in the ovary was slightly higher during the quiescence and preovulatory periods compared with the periods of recrudescence and winter dormancy. TNF-α alone significantly increased androstenedione and estradiol production by the ovary in vitro but did not augment the luteinizing hormone (LH)-induced androstenedione production. However, TNF-α did augment LH-induced estradiol production. The results of this study suggest the involvement of TNF-α in the interaction among adipose tissue accumulation, insulin resistance, and ovarian activity in S. heathi. [ABSTRACT FROM AUTHOR]

Bats are natural reservoirs of severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome CoV (MERS-CoV). Scotophilus bat CoV-512 demonstrates potential for cross-species transmission because its viral RNA and specific antibodies have been detected in three bat species of Taiwan. Understanding the cell tropism of Scotophilus bat CoV-512 is the first step for studying the mechanism of cross-species transmission. In this study, a lentivirus-based pseudovirus was produced using the spike (S) protein of Scotophilus bat CoV-512 or SARS-CoV as a surface protein to test the interaction between coronaviral S protein and its cell receptor on 11 different cells. Susceptible cells expressed red fluorescence protein (RFP) after the entry of RFP-bound green fluorescence protein (GFP)-fused S protein of Scotophilus bat CoV-512 (RFP-Sco-S-eGFP) or RFP-SARS-S pseudovirus, and firefly luciferase (FLuc) activity expressed by cells infected with FLuc-Sco-S-eGFP or FLuc-SARS-S pseudovirus was quantified. Scotophilus bat CoV-512 pseudovirus had significantly higher entry efficiencies in Madin Darby dog kidney epithelial cells (MDCK), black flying fox brain cells (Pabr), and rat small intestine epithelial cells (IEC-6). SARS-CoV pseudovirus had significantly higher entry efficiencies in human embryonic kidney epithelial cells (HEK-293T), pig kidney epithelial cells (PK15), and MDCK cells. These findings demonstrated that Scotophilus bat CoV-512 had a broad host range for cross-species transmission like SARS-CoV.

288. African Yellow Bat Scotophilus dinganii French: Scotophile de Dingane / German: Gelbbauch-Hausfledermaus / Spanish: Scotofilo de Dingane Other common names: African Yellow House Bat, Dingan’s Bat, Yellow-bellied House Bat Taxonomy. Vespertilio dinganii A. Smith, 1833, “ South Africa,—between Natal [= Durban] and Delagoa Bay [= Maputo].” See SS. wigritn. Several divergent cy tochrome-b lineages of S. dinganii suggest that cryptic species might be present, and the name colias was tentatively suggested for East African populations because they clearly differ from typical dinganii in southern Africa. Monotypic. Distribution. Widely distributed in subSaharan Africa, from Senegal and Gambia E to Eritrea, Djibouti, and Ethiopia, and S through much of E & S Africa as far S as E South Africa, Lesotho, and Swaziland. Descriptive notes. Head—body ¢. 74-90 mm, tail 46-65 mm, ear 11-22 mm, hindfoot 10-14 mm, forearm 47-60 mm; weight 15-36 g. Femalesare slightly larger than males in body measurements. Pelage is smooth,soft, and sleek. Dorsal pelage is sepia-brown, greenish brown, grayish brown, or reddish brown; dorsal hairs are paler at bases. Middorsal hairs are 6-7 mm. Ventral pelage is pale yellow, bright yellow, or orange yellow, not tinged with brown. Wings and uropatagium are dark brown and semi-translucent. Ears are comparatively short, widely separated, with strongly convex inner margin and almost straight outer margin. Tragus is moderately long, with rounded tip and concave anterior margin. Eyes are small. Testes are posterior to anus. Young of both sexes have two pairs of rudimentary nipples, but only one pair of functional nipplesis present in adult females. Skull is medium to large (greatest skull lengths 18-3-23- 5 mm) for Scotophilus; profile of skull is mostly a gentle slope from front to back, with very shallow concavity in forehead region; and sagittal crest and occipital helmet are well developed. I? is unicuspid; M' and M* have concave surfaces and indistinct ridges and appear worn; and M” is very short and has two ridges. Chromosomal complement has 2n = 36 and FNa = 52, with small acrocentric X-chromosome and small metacentric Y-chromosome in South Africa, or 2n = 36 and FNa = 50, with medium submetacentric X-chromosome and small telocentric Y-chromosome in Somalia. Habitat. Most habitats south of the Sahara, including woodland savannas and various bushland and thicket savannas; rainforests (but not Congolese rainforest); rainforestsavanna mosaics; and riverine, coastal, and montane forests. Food and Feeding. The African Yellow Bat forages by moderate fast hawking in moderately uncluttered spaces above canopies, in clearings, and over fields. It has been observed foraging near lights and drinking in streams, pools, and dams. It forages close to trees and as low as c. 2 m aboveground. Foraging is characterized by long, straight, or gently banked flights and abrupt acrobatic swerves and spectacular dives in pursuit of prey. African Yellow Bats seem to feed on beetles and other flying insects taken opportunistically. In Kenya, three stomachs contained Coleoptera, Hemiptera, Orthoptera, and Lepidoptera. Breeding. The African Yellow Bat commonly has twins, sometimes one and occasionally triplets. Based on serially sectioned reproductive tracts of females from Kruger National Park, it is seasonally monoestrous. Insemination, ovulation, and fertilization take place in April-May. Early embryonic development of normally two embryos (one in each uterine horn) was retarded, and implantation was delayed until mid-winter July) when blastocysts implanted. During the first week post-partum, a captive female licked her two young, sheltered them with one wing, and sometimes squeaked. Young stayed attached to nipples until the third night, after which they occasionally roosted beside their mother or climbed over her. Activity patterns. Aspect ratio and wing loading are medium; flight is fast and agile, with poor maneuverability. The African Yellow Bat can take off from the ground. It turns by banking and stalling-and-twisting. Scuttling, headfirst, up and down, over horizontal, sloping, and vertical surfaces has been reported. Day roosts include small holes in trees and wooden lampposts, crevices in hollow trees, narrow crevices and crannies in buildings, under eaves and roofs of corrugated iron, and in thatch. It prefers to rest on sloping or horizontal surfaces but also clings to vertical surfaces. Foraging activity begins soon after sunset, and individuals have full stomachs before dark. The African Yellow Bat tolerates high temperatures under iron roofs. In Malawi at 20-21°C, it does not become torpid during the day. Seasonal fluctuation in abundance was observed in Sudan and East Africa. In Malawi, it was more abundant in the wet season (November—February) than the rest of the year (data not available in July-August). In Zimbabwe, the African Yellow Bat is absent above elevations of 1200 m during colder months. It does not hibernate in South Africa. Average peak echolocation frequency was 33-4 kHz in St. Lucia, KwaZulu-Natal, eastern South Africa. Average peak frequency of 33-9 kHz and average duration of 4-1 milliseconds was recorded in Durban, eastern South Africa. Averages of seven calls in Soutpansberg, north-eastern South Africa, had maximum frequency of 51-6 kHz (42-1-65-2 kHz), minimum frequency of 33-1 kHz (31-6-34-1 kHz), frequency of the knee of 36-4 kHz (34-4-37-4 kHz), characteristic frequency of 33-8 kHz (31-9-35-3 kHz), and duration of 3-4 milliseconds (2-7—4-6 milliseconds). At Maroua, northern Cameroon, 19 calls were FM/QCF and had maximum frequency of 58-5 kHz (49-4-84-8 kHz), minimum frequency of 52-6 kHz (46-7-69-5 kHz), mean frequency of 55-6 kHz (48-1-77 kHz), frequency of the knee of 58-5 kHz (49-4-84 kHz), characteristic frequency of 52-7 kHz (46-8—-69-5 kHz), and duration of 0-88 milliseconds (0-73—1 milliseconds). In Swaziland, minimum frequency was 33-2 kHz (30-3-34-7 kHz), frequency of the knee was 36-4 kHz (32-1-38-6 kHz), characteristic frequency was 33-7 kHz (30-3-35-6 kHz), and duration was 3-8 milliseconds (2:6-6-1 milliseconds). Calls were detectable up to 20 m. Diurnal avian predators include bat hawks (Macheiramphus alcinus) and African harrier-hawks (Polyboroides typus). Movements, Home range and Social organization. African Yellow Bats are mostly gregarious, roosting in groups of up to 20 individuals. In KwaZulu-Natal, some roosts were occupied for at least eight years. In Zimbabwe, aggregations of hundreds of individuals foraged where termites swarmed. Of 93 African Yellow Bats mist-netted in Malawi, 66 were caught alone, six were in pairs, 14 were with another individual of the same sex, and six were in groups of two males and one female. Endoparasites include the bacteria Rickettsia and the kinetoplastid Leishmania. Ectoparasites include bedbugs Cacodmus sparsilis, Aphrania ct. barys, and Stricticimex transversus (Hemiptera, Cimicidae), the flea Charopteropsylla brockmani (Siphonaptera, Ischnopsyllidae), bat flies Basilia glabra and B. bouvieri (Diptera, Nycteribiidae), and the mite Spinturnix walkerae (Acari, Spinturnicidae).

282. Schreber’s Yellow Bat Scotophilus nigrita French: Scotophile de Schreber / German: SchreberHausfledermaus / Spanish: Scotofilo de Schreber Other common names: Giant House Bat, Giant Brown House Bat, Brown House Bat, Great Brown House Bat, Giant Yellow House Bat, Great Brown Bat, Giant Brown Bat, Schreber’s Brown Bat Taxonomy. Vespertilio nigrita Schreber, 1774, Senegal. Scotophilus nigrita was mostly referred to as S. gigas until in 1978 when it was concluded that it is the senior name for the taxon; prior to 1978, specimens called nigrita should be dinganii. Based on cytochromeb analyses, S. nigrita is paraphyletic with respect to S. colias, S. dinganui, S. nigritellus, and S. viridis. Populations of S. nigrita from West and southern Africa differ genetically by 7-6-8-1%), suggesting that nigrita might be distinct from alvenslebeni, but more extensive genetic sampling and morphological analyses are needed to take any taxonomic conclusion. Two subspecies recognized. Subspecies and Distribution. S.n.nigritaSchreber,1774—savannasofWAfrica(Senegal,IvoryCoast,Ghana,NTogo,SENigeria,andNCameroon)andSCSudan. S. n. alvenslebeni Dalquest, 1965 — savannas of E & SE Africa (E DR Congo, SE Kenya, NE Tanzania, S Malawi, E Zimbabwe, Mozambique, and NE South Africa. Descriptive notes. Head-body ¢. 103-123 mm,tail 64-92- 3 mm, ear 20-24 mm, hindfoot 17-19 mm, forearm 78-83 mm (males) and 80-88 mm (females); weight 88-91 g. Female forearm lengths are usually longer than in males. Schreber’s Yellow Bat is much larger than any other species of Scotophilus and is the largest African vespertilionid. Mid-dorsal hairs are 6-7 mm. Dorsal pelage is blackish brown, sepia-brown, greenish brown, rusty brown, or grayish brown suffused with yellow; dorsal hairs are unicolored. Ventral pelage is pale yellow to pale yellowish gray. Wings and uropatagium are blackish brown. Ears are comparatively short, separated, and blackish brown, with inner margin strongly convex and lobe at base and outer margin fairly straight with semicircular fleshy antitragus. Tragus has rounded tip and concave anterior margin. Skull is large (greatest skull lengths 27-8-32- 1 mm) for Scotophilus and has welldeveloped sagittal crest and helmet. Canines are particularly strong. Habitat. Relatively dry woodland savannas and miombo woodland savannas, usually close to rivers and riverine forests. There is one record each from dry semideciduous forest in Ghana, woodland and riverine forest mosaic in Tanzania, and rainforest zone in Nigeria. One individual was mist-netted over an almost dry river in Togo, and the individual from Tanzania was mist-netted over a pool. Food and Feeding. Schreber’s Yellow Bats probably forage high aboveground. Occlusal cusp pattern of molar teeth suggests that they are strictly carnivorous, but other teeth characters suggest that their function is to crush rather than to slice, suggesting insectivory. Breeding. No information. Activity patterns. Schreber’s Yellow Bat was found roosting under a corrugated iron roof where midday temperatures exceeded 40°C in Sudan, in a hollow of a dead Hyphaene (Arecaceae) palm in Malawi, and in a house in Zimbabwe. Echolocation call has peak frequency of 32-9 kHz. African goshawks (Accipiter tachiro) prey on Schreber’s Yellow Bat and possible lannerfalcons (Falco biarmicus), peregrine falcons (Falco peregrinus), and bat hawks (Macheiramphus alcinus). Movements, Home range and Social organization. Ectoparasites include the bedbug Cacodmus villosus (Hemiptera, Cimicidae) and the mite Spinturnix scotophili (Acari, Spinturnicidae).

271. Greater Asiatic Yellow Bat Scotophilus heathii French: Scotophile de Heath / German: Grol3e Asiatische Hausfledermaus / Spanish: Scotofilo de Heath Other common names: Asiatic Greater Yellow House Bat, Common Yellow Bat, Greater Asiatic Yellow House Bat Taxonomy. Nycticejus heathit Horsfield, 1831, Madras, India. Scotophilus heathii is genetically close to S. tandrefana and S. marovazain Madagascar and S. leucogasterin sub-Saharan Africa, being embedded in the African Scotophilus clade unrelated to the widespread Asiatic species S. kuhlii. Scotophilus heathii might include S. celebensis. Three subspecies (heath, insularis, and watkinst) have been recognized, but there is no well-defined distribution for any subspecies. Monotypic. Distribution. NE Afghanistan, Pakistan, India, Sri Lanka, Nepal, Bhutan, Bangladesh, SC & SE China (Yunnan, Guangxi, Guangdong, and Fujian) including Hainan I, Myanmar, Thailand, Laos, Vietnam (including Cat Ba and Phu Quoc Is), and N & E Cambodia. Descriptive notes. Head—body 67-93 mm, tail 43-72 mm, ear 13-20- 2 mm, hindfoot 9-15 mm, forearm 55-69 mm; weight 29-53 g. Pelage is fine and short. Dorsal pelage is dark orange to reddish brown, sometimes chestnut-brown (hair bases pale buffy brown, with darker olive-brown tips); venter is paler brownish or khaki, usually with distinct yellowish tint and occasionally reddish or golden yellow. Membranes and bare skin are dark brown. Muzzle is broad and blunt, with swollen glands on both sides and simple nostrils. Ears are small, with transverse ridges; antitragus is separated from posterior margin of ear by distinct notch and well developed; tragus is one-half the ear length and is crescent-shaped, with basal notch. Tail extends c¢. 2-3 mm past margin of uropatagium. Baculum is small and bluntly triangular in dorsal view but very thin in lateral view, and base is barely bulged. Skull is robust, with elongated and deep braincase; lambdoid crests are well developed; rostrum is short and broad; sagittal crest is variably developed but most defined posteriorly (especially in old males), bifurcates in interorbital region, and extends to front of orbits; zygomatic arches are moderately flattened; tympanic bullae are small; condylo-canine lengths are 19-21- 3 mm; I* is large, robust, and unicuspid; P* is large and is two-thirds C' height; P, is very small and tightly compressed in tooth row; P, is well developed and about two-thirds C, height. Diploid number is 2n = 36. Habitat. Urban areas and forested habitats from sea level up to elevations of ¢. 1500 m. Greater Asiatic Yellow Bats forage in forest clearings, at forest edges, over fields, and in other open habitats. Food and Feeding. Greater Asiatic Yellow Bats appear to forage by aerial hawking and usually fly less than 3-4 m aboveground. When pursuing prey, they can be less than 0-5 m aboveground and fly mostly straight with few twists and turns. They fly a few hundred meters from their roosts before returning using the same flight path. Breeding. Greater Asiatic Yellow Bats breed once a year. Copulation occurs in the second week of Novemberin Kerala and January-February in Uttar Pradesh. During the breeding season, males form harems of 2-6 females. Testes of Pakistani males increased in size from September to October; spermatogenesis peaks in November when testes double in size. There is also evidence of sperm storage in females, and ovulation and fertilization occurred after sperm was stored until the last week of December. Gestation reportedly lasts 115 days in Uttar Pradesh, births occurred in earlyJuly, lactation lasted 2-3 weeks, and weaning coincided with increased insect abundance at the beginning of monsoon season. Births in Kerala occurred in April-May. In Sri Lanka, pregnant females were reported in September—October. They give birth to 1-2 young. At birth, young weigh c. 5 g and developed quickly, reaching c. 20 g by three weeks of age. Females seem to reach maturity faster than males. Activity patterns. The Greater Asiatic Yellow Bat roosts in crevices, hollows in buildings, roofs of houses, tree hollows, crowns of palm leaf stems, and under leaves of palmyra trees. They leave roosts a little after sunset (6-26 minutes in India), generally not exiting during heavy rain. Call shape is FM sweep. In the Western Ghats, India, average start frequency was 56-7 kHz (43-2-83-8 kHz), average end frequency was 37-7 kHz (33-8-43 kHz), average peak frequency was 41-2 kHz (37-4-59-6 kHz), and average duration was 2-7 milliseconds (2-2-3-5 milliseconds). Movements, Home range and Social organization. Greater Asiatic Yellow Bats roost alone or in colonies that usually have less than 50 individuals and are sexually segregated except during breeding when males form harems. Status and Conservation. Classified as Least Concern on The [UCN Red List. The Greater Asiatic Yellow Bat is widespread and common;it does not seem to face any major threats. Bibliography.

278. Robust Yellow Bat Scotophilus robustus French: Scotophile robuste / German: Robuste Hausfledermaus / Spanish: Scotofilo robusto Taxonomy. Scotophilus robustus Milne-Edwards, 1881, Madagascar. Based on multivariate analyses of forearm and cranial measurements, S. robustus is distinct from dinganii and borbonicus. Monotypic. Distribution. Endemic to Madagascar. Descriptive notes. Head-body ¢.93 98 mm, tail 55-70 mm, ear 17-20 mm, hindfoot 10-13 mm, forearm 62-65 mm; weight ¢.40- 5—49 g. Dorsum and venter are medium brown. Baculum is flat and triangular, with distinct indentation to proximal margin. Skull is large (greatest skull lengths 24-2-25- 6 mm) for Scotophilus, but rostrum is comparatively short; sagittal crest is well developed; occipital helmet is present; and profile of skull mostly slopes from front to back, with very shallow concavity in forehead region. I? is unicuspid; M' and M? have concave surfaces and indistinct ridges and appear worn; and M” is very short and has two ridges. Habitat. All distinct biomes of Madagascar, except spiny bush and apparently humanoccupied habitats, from sea levelto elevations up to c¢. 1400 m. Food and Feeding. Coleoptera, Lepidoptera, Homoptera, and Blattodea were found in feces of two individuals. Coleoptera comprised ¢.68% of diet by volume, but sampling in the feeding area showed that only 3% of available prey was Coleoptera, suggesting that the Robust Yellow Bat is a coleopteran specialist. Feces of three bats contained Araneae, Coleoptera, Diptera, Homoptera, Hymenoptera, Lepidoptera, and Orthoptera. Breeding. No information. Activity patterns. Calls of Robust Yellow Bats were characterized by broadband steep FM,followed by QCF at LDC. Fundamental call was always most intense, with peak energy of 38-1 kHz. Movements, Home range and Social organization. Ectoparasites of Robust Yellow Bats included Basilia nov. sp. (Diptera, Nycteribiidae) and Basilia (Paracyclopodia) sp., the latter infected by Bartonella and Enterobacteriales. Status and Conservation. Classified as Least Concern on The IUCN Red List.

275. Marovaza Yellow Bat Scotophilus marovaza French: Scotophile de Marovaza / German: Marovaza-Hausfledermaus / Spanish: Scotofilo de Marovaza Other common names: Marovaza House Bat Taxonomy. Scotophilus marovaza Goodman, Ratrimomanarivo & Randrianandrianina, 2006, “ Madagascar, Province de Mahajanga, Marovaza, 14°56’S, 47°16’E, 5 m above sea level.” This species is monotypic. Distribution. Known from three localities in W Madagascar (Marovaza, Ankarafantsika, and Mahabo); it might occur across much of W lowland Madagascar. Descriptive notes. Head-body c.62 68 mm, tail 38-45 mm, ear 13-15 mm, hindfoot 6-6- 5 mm, forearm 41-45 mm; weight 12-5-16- 8 g. Dorsal pelage is relatively short, reddish brown, except for distinctly lighter, brownish red band across central back; venter and throat are uniform shiny light brownish yellow. Wings and uropatagium are dark brownish black. Muzzle is broad and short, with pug-like appearance. Distinct rostral swelling occurs anterior to eyes. Nostril openings are crescent-shaped and pointed outwardly. Tragus is notably long and sickle-shaped and tapers to fine point at apex; outer margin is convex and has circular lobe at its base. Antitragus is a well-developed,slightly asymmetric, semi-round structure (3 mm wide x 2 mm high) and is separated from ear by distinct notch. Baculum is flat and triangular, with rounded, expanded proximal part that gradually tapers to rounded distal tip. Skull is small (greatest skull lengths 16-4-16- 9 mm) for Scotophilus; sagittal crest is well developed, particularly in males, bifurcates at level of interorbital region, and extends as weak crest to front of orbits and posteriorly in a helmet; lambdoid crests are not well developed; rostrum is comparatively short and broad, without notable expansion or swelling in lacrimal region; zygomatic arches have slight ovoid flaring; interorbital constriction is not pronounced; anterior emargination of palate is relatively deep and broad; and posterior palatal extension terminates as small acute spine. I* is trifid; M' and M? have reduced mesostyle; M! has distorted W-shaped cusp pattern; M* has distinct W-shaped cusp pattern; M? is greatly reduced in size; and trigonid of lower premolarsis larger than talonid. Habitat. Ecotones of savanna and disturbed dry lowland deciduous forest, in and around villages, open areas close to natural forests, dry riverbeds at edge of slightly disturbed dry deciduous forests from sea level up to elevations of ¢. 200 m. Food and Feeding. No information. Breeding. One Marovaza Yellow Bat captured at Ankarafantsika in late November had greatly enlarged mammae, appearing to be lactating. One male from Marovaza collected in early December had enlarged descended testes (8 x 3 mm) and convoluted epididymis. Three of four individuals obtained at Marovaza in late April were adult females, with large or slightly enlarged mammae, no embryos, and single placental scars in one uterine horn, and one was an adult male with enlarged descended testes (9 x 4 mm) and convoluted epididymis. A defined breeding season of females might coincide with start of rainy season (November—February); males seem to maintain reproductive capability during longer parts of the year. Activity patterns. Two Marovaza Yellow Bats were captured c.1-5 hours after sunset and two hours before sunrise when they exited and entered roost sites. Holotype and two other individuals were collected in a day roost in dry palm leaves (Bismarckia nobilis, Arecaceae) forming the roof of a building in a small pocket formed by curled dried leaves of the palm, just anterior to the leaf stem. Palm fronds are probably natural day roosting sites. Based on nine individuals, calls were broadband steep FM followed by QCIF, and individuals emitted LDC calls, with maximum energy at 45-9 kHz. Remains of one individual were found in pellets of bat hawk (Macheiramphus alcinus). Movements, Home range and Social organization. Marovaza Yellow Bats formed groups of less than five individuals in huts made from palm leaves. Ectoparasites include Basilia (Paracyclopodia) sp. (Diptera, Nycteribiidae). Status and Conservation. Classified as Least Concern on The IUCN Red List. Bibliography. Goodman, Jenkins & Ratrimomanarivo (2005), Goodman, Ratrimomanarivo & Randrianandrianina (2006), Kofoky et al.

270. Sody’s Yellow Bat Scotophilus collinus French: Scotophile de Sody / German: Sody-Hausfledermaus / Spanish: Scotofilo de Sody Other common names: Sody'’s Yellow House Bat Taxonomy. Scotophilus temmincki collinus Sody, 1936, Djembrana (= Jembrana Regency), ca. 50 m, Bali, Indonesia. Scotophilus collinus has often been included under S. kuhlii, but it is generally recognized as a distinct species based on morphology. There might be two subspecies of S. collinus based on morphometric analyses: one In the east and the other in the west. Monotypic. Distribution. NW & C Borneo, W Java, Bali, Lombok, Flores, Lembata, Sumba, Sawu, Timor, Semau, Roti, Banda, and Aru Is. Descriptive notes. Head-body 55- 7-71 mm, tail 27- 8-52 mm, ear 12:3-15- 1 mm, hindfoot 6-7-9- 7 mm, forearm 44-5-51- 9 mm; weight 18-23 g. Sody’s Yellow Bat is similar to the Lesser Asiatic Yellow Bat (S. kuhlii). Western form has smaller average skull characteristics than eastern form, but external measurements are generally larger. Dorsal pelage is dark brown; venter is paler straw yellow. Bare skin is olive-brown. Muzzle is broad and blunt, with swollen glands on both sides and simple nostrils. Ears are small, with transverse ridges; antitragus is separated from posterior margin of ear by distinct notch and well developed; tragusis one-half the ear length and is crescent-shaped with basal notch. Tail extends c. 2-3 mm past margin of uropatagium. Compared with the Lesser Asiatic Yellow Bat, skull is shorter; rostrum is broader; cranium is broad but less inflated, giving slenderer impression; zygomatic width is considerably narrower; palate is broader; and mesopterygoid fossa and distance between cochleae are broad. Habitat. Urban areas and rocky, forested offshore islands. Food and Feeding. No information. Breeding. No information. Activity patterns. Sody’s Yellow Bat often roosts in roofs of houses. Movements, Home range and Social organization. No information. Status and Conservation. Classified as Least Concern on The IUCN Red List. Virtually nothing is known regarding ecology and threats of Sody’s Yellow Bat. It is apparently common in some parts of Borneo. Bibliography. Helgen & Wilson (2002), Kitchener et al.

279. Lesser Yellow Bat Scotophilus borbonicus French: Scotophile de Bourbon / German: Kleine Hausfledermaus / Spanish: Scotofilo de la Isla de Reunion Other common names: Lesser Yellow House Bat, Bourbon Bat Taxonomy. Vespertilio borbonicus E. Geoffroy Saint-Hilaire, 1803, Ile Bourbon [= Réunion Island], Réunion. See S. robustus. The name borbonicus is restricted to the Réunion Island form. Monotypic. Distribution. Confirmed from Réunion I; in Madagascar, known only from a single specimen collected in the SW, butthis record cannot be confirmed; records from Mauritius are erroneous. Descriptive notes. Forearm 51 mm (one specimen). The Lesser Yellow Bat is known from only one individual in very poor condition. Dorsum of the specimen is apparently reddish brown, and venteris whitish, which matches original description by E. Geoffroy Saint-Hilaire in 1803. Habitat. No information. Food and Feeding. No information. Breeding. No information. Activity patterns. Some echolocation calls of two unidentified bats were recorded during fieldwork on Réunion. Signals of one call from “ Chiroptera spl” (QFC = 60 kHz and FM = 61 kHz) were very similar to those of Madagascan and African continental species of Scotophilus, suggesting that it might have been the Lesser Yellow Bat.
