Kerivoula papillosa Temminck, 1840 Papillose woolly bat New records Lampung Province: Sukabanjar Forest, Way Canguk Forest. New material Two individuals were collected as voucher specimens. Lampung Province: Way Canguk Forest, 1♂, 1♀ (MZB 35887, 35888). Previous records from Sumatra One individual was collected from Sumatra (van Strien, 1996), but no locality information was given. Remarks This is the largest Kerivoulinae species in the study area. All individuals were caught with harp traps between 50–1,033 m a.s.l. in forest. Individuals varied in color; while most individuals were brown or grayish-brown, others were yellowishbrown. We followed existing references allocating all Kerivoula with forearm length> 42.0 mm to K. papillosa (Table 3). Five individuals, both with FA = 40.6–41.5 mm, were not assigned to species as this falls within the range of both K. lenis and K. papillosa (Table 3). We did not consider K. kachinensis, another large brown Kerivoula species (FA = 40.1–43.2 mm; BM = 6.5–9.5 g) in Southeast Asia, because its distribution is restricted to the Indo-Burma region (Bates et al., 2004; Soisook et al., 2007)., Published as part of Huang, Joe Chun-Chia, Jazdzyk, Elly Lestari, Nusalawo, Meyner, Maryanto, Ibnu, Maharadatunkamsi, Wiantoro, Sigit & Kingston, Tigga, 2014, A recent bat survey reveals Bukit Barisan Selatan Landscape as a chiropteran diversity hotspot in Sumatra, pp. 413-449 in Acta Chiropterologica 16 (2) on page 432, DOI: 10.3161/150811014X687369, http://zenodo.org/record/3943617, {"references":["VAN STRIEN, N.

Pteropus ? vampyrus (Linnaeus, 1758) Large flying fox New records Lampung Province: Lombok Village, Sukaraja Forest, Sukaraja Village, Sumberjaya Village, Sumber Rejo Village. Previous records from Sumatra Jambi Province: Muara Bungo; West Sumatra Province: Mininjau; Lampung Province: Krui, Rata Agung (Sibuea and Herdimansyah, 1993); as throughout Sumatra by van Strien (1996). Remarks Although we did not capture any Pteropus, four were observed flying in Lombok Village near sunset in late September 2011. Twenty-five individuals were also observed in Sukaraja Village flying south toward Sukaraja Forest from the northeast at around 18:00 in mid April 2012. The bats in the Sukaraja area were possibly from a roost on a small island in ‘Watermelon Bay’ (Teluk Semangka in Indonesian) near the north coast of southern Bukit Barisan Selatan Ridge (J. Yanto, personal communication). Three Pteropus species are currently known from Sumatra, namely P. vampyrus (large flying fox), P. melanotus (black-eared flying fox), and P. hypomelanus (variable flying fox) (Corbet and Hill, 1992; Simmons, 2005). Pteropus melanotus and P. hypomelanus are only known from a few offshore islands in northern Sumatra (Simmons, 2005; Boitani et al., 2006), but P. vampyrus has been reported throughout the island (van Strien, 1996), including BBSL (Sibuea and Herdimansyah, 1993) and nearby areas (this study, see below). Hence, we tentatively assign all observations of flying foxes to P. vampyrus. Farmers throughout the study area reported in interviews that P. vampyrus gather in coffee plantations to roost and forage during the fruiting season. In the coastal area near Sumber Rejo-Way Canguk area, local people used kites with hooks on tethers to hunt commuting P. vampyrus. Villagers gathered at dusk and raised kites into the commuting route of bats until sunset. One to two black plastic bags were tied to the tethers to simulate flying bats and decrease the bats’ awareness of the kites (JCCH, personal observation). Based on interviews with villagers, one to ten flying foxes were captured by the whole village each night in 2010; 30 years ago the average capture rate was as many as five bats per person per night. P. vampyrus were sold (2–20 USD per bat) as medicine for asthma at local markets near the study area.

Rhinolophus lepidus Blyth, 1844 / R. pusillusTemminck, 1834 Blyth’s horseshoe bat/Least horseshoe bat New records Lampung Province: Lombok Village, Pemerihan Village, Sukaraja Forest, Sukaraja Village, Way Canguk Forest. New material Four individuals were collected as specimens. Lampung Province: Pemerihan Village, 1♀ (MZB 35051); Sukaraja Forest, 1♂, 1♀ (MZB 35795, 35796); Way Canguk Forest, 1♀ (MZB 35798). Previous records from Sumatra North Sumatra Province: Deli for R. lepidus (van Strien, 1996); Medan for R. pusillus (Csorba et al. 2003). Remarks This small Rhinolophus can be distinguished from other Rhinolophus species either by its smaller body size or by the shape of the connecting process, which is triangular and pointed at the tip. The posterior noseleaf (lancet) is triangular and pointed at tip. The coloration is light brown, grayish brown, or orange tipped with buffy brown. Individuals are generally characterized by yellowish brown and yellow skin of the face. Based on the characters above, this bat is most similar to R. lepidus and R. pusillus in the pusillus species group. The two Rhinolophus are hard to be distinguished externally and the taxonomic relationship between the two species is not clear (Csorba et al., 2003). Some studies suggest that peak frequency (F MAXE) is a diagnostic trait to distinguish R. lepidus and R. pusillus (Kingston et al., 2000; Zhang et al., 2009; Hughes et al., 2010). However, the discrepancy in echolocation calls reported from those studies indicates there is no clear relationship between peak frequency and species (R. lepidus versus R. pusillus: 100 kHz and 92.5 kHz in Kingston et al., 2000; 92–95 kHz and 100–111 kHz in Zhang et al., 2009; 100.1 kHz and 112.5 kHz in Hughes et al., 2010). Thus, we are not able to assign our samples to either of the two species. Individuals were captured with harp traps with an elevation from 50–507 m a.s.l. in lowland rainforest as well as plantations near forest in our study area. It was recorded roosting in the Gimbar 2 cave at Way Canguk Forest, and using houses as night roosts and feeding sites in Pemerihan Village., Published as part of Huang, Joe Chun-Chia, Jazdzyk, Elly Lestari, Nusalawo, Meyner, Maryanto, Ibnu, Maharadatunkamsi, Wiantoro, Sigit & Kingston, Tigga, 2014, A recent bat survey reveals Bukit Barisan Selatan Landscape as a chiropteran diversity hotspot in Sumatra, pp. 413-449 in Acta Chiropterologica 16 (2) on page 429, DOI: 10.3161/150811014X687369, http://zenodo.org/record/3943617, {"references":["VAN STRIEN, N.

Megaerops ecaudatus (Temminck, 1837) Temminck’s tailless fruit bat New records Lampung Province: Kuyung Arang Village, Sukabanjar Village, Sukaraja Forest, Sukaraja Village, Sumber Rejo Village, Way Canguk Forest. New material Two individuals were collected as voucher specimens. Lampung Province: Sukaraja Village, 1♂, 1♀ (MZB 35004, 35005). Previous records from Sumatra West Sumatra Province: Mininjau (Sibuea and Herdimansyah, 1993), Padang (type locality, Simmons, 2005). Remarks All M. ecaudatus individuals in our study were captured in mist nets set at ground level at elevations up to 618 m a.s.l. in coffee plantations. Although most reports describing M. ecaudatus from forested habitats (Francis, 2008), records of M. ecaudatus in other disturbed habitats is recently reported by Sritongchuay et al. (2014) as well. One museum specimen (MZB 35003) indicates a presence of M. ecaudatus in Way Canguk Forest. It is distinguished from M. wetmorei by shorter tibia length and brown on the first phalanges of all fingers.

Myotis sp. 1 New records Lampung Province: Kuyung Arang Village, Sukabanjar Village, Sumber Rejo Village. New material Three individuals were collected as voucher specimens. Lampung Province: Sumber Rejo Village, 2♂♂ (MZB 34970, 34990), Sukabanjar Village, 1♀ (MZB 35045). Remarks This is a small Myotis species (FA = 31.4–34.7 mm) with the wing membrane attached at the base of the toes. The fur is dark brown to black on the upperparts and grayish brown on the underparts. Some individuals have slightly shiny-tipped fur on the upperparts. The skull is generally flat and the second upper premolar is intruded from the toothrow. In comparison to all known Myotis species of the Sunda Shelf, it is similar to Myotis ater in its cranial and dental characters, but differs in the range of forearm length (FA is 34.0–39.0 mm in M. ater — Kingston et al., 2006). The body size and dental characters are similar to M. siligorensis (Yasuma et al., 2003; Kingston et al., 2006) but cranial characters differ (SW, unpublished data). Neither M. ater nor Myotis siligorensis have been recorded on the Sumatran main island although there is a record of M. ater from an offshore island in West Sumatra (Simmons, 2005). Further comparison and molecular analyses are necessary to clarify the taxonomic status of this species. In the study area, it was distinguished from other Myotis species, except M. muricola, by its smaller forearm length. It is indistinguishable from M. muricola externally, but can be differentiated by the tooth arrangement: the second upper premolar (P 3) is in line with the toothrow in M. muricola and displaced inwards such that the adjacent premolars are in contact or nearly so in Myotis sp. 1 (Corbet and Hill, 1992). Individuals were caught with both harp traps and mist nets at ground level in coffee plantations, and sometimes trapped with M. muricola., Published as part of Huang, Joe Chun-Chia, Jazdzyk, Elly Lestari, Nusalawo, Meyner, Maryanto, Ibnu, Maharadatunkamsi, Wiantoro, Sigit & Kingston, Tigga, 2014, A recent bat survey reveals Bukit Barisan Selatan Landscape as a chiropteran diversity hotspot in Sumatra, pp. 413-449 in Acta Chiropterologica 16 (2) on page 435, DOI: 10.3161/150811014X687369, http://zenodo.org/record/3943617, {"references":["KINGSTON, T., B.

Kerivoula krauensis Francis, Kingston, and Zubaid, 2007 Krau woolly bat New record New record to Sumatra, Lampung Province: Way Canguk Forest. Remarks Two adults of K. krauensis were collected by previous researchers from Way Canguk Forest (MZB 31480, 34995). This is the first record of this small Kerivoula species in Sumatra. The records extend the distribution of K. krauensis to the Greater Sunda islands after it was first described from Peninsular Malaysia (Francis et al., 2007). It is distinguished from all known Kerivoula species in Sumatra by darker coloration and golden shiny tipped fur on upperparts (Yasuma et al., 2003; Francis et al., 2007) and from Phoniscus atrox by lack of a notch near the base of tragus at external margin and lack of a groove on the canine., Published as part of Huang, Joe Chun-Chia, Jazdzyk, Elly Lestari, Nusalawo, Meyner, Maryanto, Ibnu, Maharadatunkamsi, Wiantoro, Sigit & Kingston, Tigga, 2014, A recent bat survey reveals Bukit Barisan Selatan Landscape as a chiropteran diversity hotspot in Sumatra, pp. 413-449 in Acta Chiropterologica 16 (2) on pages 431-432, DOI: 10.3161/150811014X687369, http://zenodo.org/record/3943617, {"references":["FRANCIS, C.

Rhinolophus sp. 2 New record Lampung Province: Way Canguk Forest. Remarks A single adult male was collected by previous researchers from Way Canguk Forest, but recognized as a R. lepidus (MZB 31493). It is a small brown Rhinolophus bat with a FA of 39.9 mm. The posterior noseleaf is nearly triangular, barely hairy at base, and with a long lancet blunted at the tip. The connecting process is round, differing from R. lepidus / R. pusillus, and the sella is tapered. This species is morphologically similar to R. malayanus in Indo-Burma region (Csorba et al., 2003), but not comparable to any species known from the Sunda Shelf. It is also similar to R. stheno, in noseleaf structure, but smaller in all external measurements. Further comparison with more species is necessary to identify the species., Published as part of Huang, Joe Chun-Chia, Jazdzyk, Elly Lestari, Nusalawo, Meyner, Maryanto, Ibnu, Maharadatunkamsi, Wiantoro, Sigit & Kingston, Tigga, 2014, A recent bat survey reveals Bukit Barisan Selatan Landscape as a chiropteran diversity hotspot in Sumatra, pp. 413-449 in Acta Chiropterologica 16 (2) on page 430, DOI: 10.3161/150811014X687369, http://zenodo.org/record/3943617, {"references":["CSORBA, G., P.

Kerivoula minuta Miller, 1898 Least woolly bat New records New record to Sumatra; Lampung Province: Sukaraja Forest, Sukaraja Village, Way Canguk Forest. New material One individual was collected as a voucher specimen. Lampung Province: Way Canguk Forest, 1♂ (MZB 35889). Remarks This was the smallest Kerivoula in our study area (FA = 27.7–30.0 mm; Wt: 2.3–3.3 g). All individuals were caught with harp traps between 50–572 m a.s.l., in forest except one, which was trapped in the understory of a mixed coffee plantation. It is a light reddish-brown bat with semi-translucent wing membranes. Body size is smaller than other Kerivoula species in the study area. The bats are externally similar to K. minuta and K. intermedia, two small species coexisting in some forests of Borneo and Peninsular Malaysia (Kingston et al., 2003; Struebig et al., 2010). These two Kerivoula species are almost morphologically identical but differ in body mass (2.0–3.0 g for K. minuta and 3.1–3.5 g for K. intermedia) and cranial measures (Khan et al., 2010). Based on the measures of body mass, all our captures can be assigned to K. minuta, except one individual with a BM of 3.3 g, which falls into the range of K. intermedia. A detailed study of cranial traits of our sample collected also confirms the presence of K. minuta in our study area (B. Douangboubpha, personal communication).

Hipposideros cervinus (Gould, 1854) Fawn-colored leaf-nosed bat New records Lampung Province: Lombok Village, Sukaraja Forest, Sumber Rejo Village, Way Canguk Forest. Previous records from Sumatra North Sumatra Province: Sukaranda (upper Langkat) (Bates et al., 2007 a). Remarks This medium-sized hipposiderid bat can be easily distinguished from other Hipposideros in the study area by the presence of two lateral leaflets on the muzzle either side of the anterior nose leaf. In our surveys, most individuals were captured with harp traps set in the lowland primary rainforest of Way Canguk, and another six individuals were caught in coffee plantations. A single individual was recorded from Gimbar 2 cave of Way Canguk.

Miniopterus pusillus Dobson, 1876 Small long-fingered bat New records Lampung Province: Sumber Rejo Village, Way Canguk Forest. Previous records from Sumatra North Sumatra Province: a cave near Penerukan (Whitten et al., 2000); caves near Bohorok (van Strien, 1996). New material One individual was collected as a voucher specimen. Lampung Province: Way Canguk Forest, 1♀ (MZB 35821). Remarks This is a medium-sized Miniopterus species. All individuals were captured in or near the Gimbar 2 cave within Way Canguk Forest, except one individual from Sumber Rejo Village. The skin on the face is dark brown and the tragus is pale white to grayish brown. It can be distinguished from M. australis by the larger size and skin coloration of the face and from M. magnater by the smaller body size (Table 2) in our study area. Comparing with other known Miniopterus species on the Sunda Shelf, its forearm length falls into the range of M. pusillus and M. medius, and partially overlaps with M. fuliginosus. It has a similar body mass range to M. pusillus, overlaps partially with M. medius, and lighter than M. fuliginosus. Its tibia length overlaps partially with M. pusillus, falls into the range of M. fuliginosus, and is longer than in M. medius (Table 4). Despite its slightly larger tibia length, we tentatively assign this bat as M. pusillus based upon its forearm length and body mass. Further comparison of craniodental characters and genetic analyses are necessary to confirm the identification of this species., Published as part of Huang, Joe Chun-Chia, Jazdzyk, Elly Lestari, Nusalawo, Meyner, Maryanto, Ibnu, Maharadatunkamsi, Wiantoro, Sigit & Kingston, Tigga, 2014, A recent bat survey reveals Bukit Barisan Selatan Landscape as a chiropteran diversity hotspot in Sumatra, pp. 413-449 in Acta Chiropterologica 16 (2) on page 439, DOI: 10.3161/150811014X687369, http://zenodo.org/record/3943617, {"references":["WHITTEN, A.

Rhinolophus borneensis Peters, 1861 / R. celebensis K. Anderson, 1905 Bornean horseshoe bat/ Sulawesi borseshoe bat New records New record to Sumatra; Lampung Province: Kuyung Arang Village, Lombok Village, Sukabanjar Forest, Sukaraja Forest, Sukabanjar Village, and Way Canguk Forest. New material Three individuals were collected as voucher specimens. Lampung Province: Sukaraja Forest, 1♂, 2♀♀ (MZB 35874–35876). Remarks This medium-sized Rhinolophus species was captured at an elevational of 50–923 m a.s.l. in forest and plantations in mountain areas. This species has a tapered or nearly parallel-sided sella, and a roughly rounded connecting process. Individuals are also characterized by orangey facial skin and bright yellowish or reddish-orange fur. Based on the characters above, this bat is most similar to R. borneensis and R. celebensis in the megaphyllus species group. The two Rhinolophus are hard to be distinguished externally and the taxonomic relationship between the two species is not clear. The current identification is based upon their distribution ranges (Csorba et al., 2003). Rhinolophus borneensis is known from Borneo and Java; R. celebensis from Java, Bali, Sulawesi, and Timor. Neither species has been recorded yet in Sumatra (Suyanto et al., 2002; Simmons, 2005; also see Francis, 2008, for the revised status of mainland Southeast Asia populations). Hence, we are not able to assign our samples to either of the two species. In our study area, it can be distinguished from R. affinis by its less concave sella, from the pusillus group (R. acuminatus, R. lepidus) by its roughly rounded connecting process, and from the trifoliatus group (R. trifoliatus, R. luctus) by the lack of lateral lappets and smaller body size. Noteworthy, variations in the connecting process (round and slightly pointed) and sella (nearly parallel, slightly concave, and slightly step-wised near base) were observed in individuals from Way Canguk Forest and Sukaraja Forest., Published as part of Huang, Joe Chun-Chia, Jazdzyk, Elly Lestari, Nusalawo, Meyner, Maryanto, Ibnu, Maharadatunkamsi, Wiantoro, Sigit & Kingston, Tigga, 2014, A recent bat survey reveals Bukit Barisan Selatan Landscape as a chiropteran diversity hotspot in Sumatra, pp. 413-449 in Acta Chiropterologica 16 (2) on page 429, DOI: 10.3161/150811014X687369, http://zenodo.org/record/3943617, {"references":["CSORBA, G., P.

Previous records from Sumatra North and South Sumatra Provinces (van Strien, 1996); West Sumatra Province: Mentawai Islands (Simmons, 2005); Bengkulu Province: Enggano Island (Francis et al., 2007). Remarks This is a small grayish-brown Kerivoula species commonly found in the study area. All individuals were caught between 50–995 m a.s.l. in forest, except two, which were trapped in coffee plantations. Comparing with known brown Kerivoula species on the Sunda Shelf, its forearm length and body mass fall into the range of K. hardwickii (Table 3). It was smaller than K. papillosa, and slightly larger than K. whiteheadi. It overlapped with K. flora and K. lenis in forearm length but can be separated from this species by body mass. (Table 3). In K. whiteheadi the first two upper premolars are elongated, which they are not in K. hardwickii (Yasuma et al., 2003).

Macroglossus sobrinus Andersen, 1911 Greater long-nosed fruit bat New records Lampung Province: Kuyung Arang Village, Sukaraja Forest, Sukaraja Village, Sumber Rejo Village. New material Two individuals were collected as voucher specimens. Lampung Province: Sumber Rejo Village, 2♂♂ (MZB 34967, 35837). Previous records from Sumatra West Sumatra Province: Mentawai Islands (Simmons, 2005). Remarks Macroglossus sobrinus was captured in both coffee plantations and forest. It can be distinguished from E. spelaea and Rousettus by smaller size and from the rest of pteropodid species by relatively narrower muzzle and longer tongue.

Hipposideros ater Templeton, 1848 Dusky leaf-nosed bat New records Lampung Province: Kuyung Arang Village, Sumber Rejo Village. New material One individual was collected as a voucher specimen. Lampung Province: Way Canguk Forest, 1♀ (MZB 34983). Previous records from Sumatra Lampung Province: Way Canguk Forest (Khan, 2013). Remarks This small species can be distinguished from most Hipposideros by smaller body size (Table 2) and from H. doriae by presence of vertical septa in the posterior noseleaf. In comparison with species of the bicolor -group known for the Sunda Shelf, the body size and noseleaf shape were closest to those of H. ater, H. cineraceus, and H. dyacorum (Corbet and Hill, 1992; Yasuma et al., 2003; Francis, 2008). The internarial septum is pinkish or grayish purple, and the top half of the ear is rounded, contrasting with the darkish septum and triangular ears of H. dyacorum. The internarial septum is swollen at the base and gradually narrows towards the top, a condition similar to H. ater from Pahang state of Malaysia and different from H. cineraceus from Pahang, in which the internarial septum is swollen at the middle (Kingston et al., 2006) and H. dyacorum from Malaysia which is very narrow (Murray et al., 2012). Khan’s (2013) molecular analysis included one sample from Way Canguk Forest and found it to be genetically identical to the Java population of H. ater (as H. a. saevus -1 by the author). In our study area, it is smaller than H. bicolor (see species account below) but bigger than H. doriae, and can be distinguished from H. cervinus by absence of lateral leaflets on the muzzle and smaller body size., Published as part of Huang, Joe Chun-Chia, Jazdzyk, Elly Lestari, Nusalawo, Meyner, Maryanto, Ibnu, Maharadatunkamsi, Wiantoro, Sigit & Kingston, Tigga, 2014, A recent bat survey reveals Bukit Barisan Selatan Landscape as a chiropteran diversity hotspot in Sumatra, pp. 413-449 in Acta Chiropterologica 16 (2) on page 426, DOI: 10.3161/150811014X687369, http://zenodo.org/record/3943617, {"references":["KHAN, F.

Cynopterus brachyotis (Müller, 1838) Lesser short-nosed fruit bat New records Lampung Province: Kuyung Arang Village, Lombok Village, Sidodadi Village, Sukabanjar Village, Sukaraja Forest, Sukaraja Village, Sumberjaya Village, Sumber Rejo Village. New material Six individuals were collected as voucher specimens. Lampung Province: Sumberjaya Village, 1♀ (MZB 34971); Sumber Rejo Village, 4♂♂, 1♀ (MZB 34956, 34958, 34973, 34974, 35806). Previous records from Sumatra Throughout Sumatra (see detailed localities in Kitchener and Maharadatunkamsi, 1991). Remarks In our study area, the C. brachyotis- like bats exhibit two distinct morphological forms. One has ears with a straight or slightly notched posterior edge, and has a larger body size; the ears of the other morph have a curved margin to the posterior edge and body size is smaller (Table 2). The two morphs also differed in habitat use; whereas the larger morph was usually abundant in disturbed habitats but rare within forested habitats, the capture rate of the small morph was generally high in all surveyed habitats. Notably, in contrast to the irritable and noisy behaviors of other Cynopterus species, most individuals of the small Cynopterus were generally calm and silent either in nets or during processing. Campbell et al. (2004) described five cytochrome b lineages of C. brachyotis complex in South and Southeast Asia, two of which were from the Sunda Shelf and described as Forest and Sunda lineages. The two Sunda Shelf C. brachyotis lineages also differ in body size and habitat use; C. brachyotis Forest lineage has a smaller forearm length (FA = 54.3–63.7 mm) and is associated with forest, contrasting with the larger C. brachyotis Sunda lineage (FA = 60.0–70.0 mm) associated with disturbed habitats. Nevertheless, the authors did not assign either to C. brachyotis because they were not able to make comparisons with type material (Campbell et al., 2004). Three following publications (Abdullah and Jayaraj, 2006; Jayaraj et al., 2012; Fong et al., 2013) confirmed the presence of two distinct morphs of ‘ C. brachyotis ’ in Malaysia and their ecological preferences in habitat. By a preliminary morphological comparison with the holotype of C. brachyotis, Abdullah and Jayaraj (2006) further suggested that Malaysia’s large morph was the nominate species and the small form is a different species. Interestingly, C. minutus, which was first described from the Mentawai Islands off the west coast of Sumatra, is similar in body size to the small forest C. brachyotis of Malaysia. Cynopterus minutus is commonly found on all the Greater Sunda Islands and is frequently sympatric with C. brachyotis (Kitchener and Maharadatunkamsi, 1991). Unlike the two Malaysian lineages, Kitchener and Maharadatunkamsi (1991) reported overlap in radius length of C. minutus (52.9–61.9 mm) and C. brachyotis (54.7–66.7 mm) in Indonesia. However, the authors included juveniles and subadults in their samples (Kitchener and Maharadatunkamsi, 1991), which may have smaller forearm lengths (Elangovan et al., 2003). The taxonomic relationship between C. minutus and the small forest C. brachyotis remains unclear. Given the above, we regard the two morphs of C. brachyotis- like bats in our study as different species, and assign the large morph to C. brachyotis (as C. brachyotis Sunda in Campbell et al., 2004). Our samples of the small round-eared Cynopterus are comparable in forearm length (56.5–61.6 mm, x = 57.2 mm) to both C. minutus (52.9–61.9 mm, x = 57.5 mm — Kitchener and Maharadatunkamsi, 1991) and C. brachyotis Forest (54.3–63.7 mm, x = 58.1 mm — Campbell et al., 2004), and C. cf. brachyotis Forest (Jayaraj et al., 2012). Similar to C. minutus in using both primary forest and disturbed habitats (IUCN, 2013), the small Cynopterus from BBSL is also a habitat generalist, which differs from C. brachyotis Forest, a forest specialist (Campbell et al., 2004; Abdullah and Jayaraj, 2006; Jayaraj et al., 2012). Although the previous studies do not provide for comparisons of behavior and ear shape in C. minutus and C. brachyotis Forest, we tentatively regard the small form as C. minutus based on similarities of body size and habitat use. Cynopterus brachyotis (the large form) was the most abundant pteropodid species in the study area. Capture rates were usually high in coffee plantations, forest edges and river habitats but low within forests. In our study area, C. brachyotis can be distinguished from C. sphinx by shorter ears (C. brachyotis and> 18.0 mm in C. sphinx) and from C. horsfieldii by the absence of peg-like cusps on the lower cheek teeth and ear shape (straight or slightly notched at posterior edge in C. brachyotis, strongly notched in C. horsfieldii)., Published as part of Huang, Joe Chun-Chia, Jazdzyk, Elly Lestari, Nusalawo, Meyner, Maryanto, Ibnu, Maharadatunkamsi, Wiantoro, Sigit & Kingston, Tigga, 2014, A recent bat survey reveals Bukit Barisan Selatan Landscape as a chiropteran diversity hotspot in Sumatra, pp. 413-449 in Acta Chiropterologica 16 (2) on page 419, DOI: 10.3161/150811014X687369, http://zenodo.org/record/3943617, {"references":["KITCHENER, D.

Hipposideros bicolor (Temminck, 1834) Bicolored leaf-nosed bat New record Lampung Province: Sukaraja Forest, Sumber Rejo Village. Previous records from Sumatra North Sumatra Province: Bua Bua, Enggano Island (belong to Nias Islands) (as H. gentilis major in Andersen, 1918, but see Douangboubpha et al., 2010); Lampung Province: Way Canguk Forest (Khan, 2013). Remarks This is a medium-sized species of the bicolor group with forearm length ranging from 43.8 to 47.1 mm (n = 15) and ear length from 15.4 to 19.7 mm (n = 11). There are two bicolor -group species from mainland Southeast Asia which overlap in forearm and ear length, namely Hipposideros bicolor (as H. bicolor 131 kHz in Kingston et al., 2001) and H. atrox (as H. bicolor 142 kHz in Kingston et al., 2001), which are both confirmed from Sumatra (Douangboubpha et al., 2010). In the past, the similarity of external traits and the unclear taxonomic relationships among geographic populations has made identification in the field difficult. Previous studies suggest that peak frequency of the echolocation call (F MAXE, frequency with maximum energy of a call) is a diagnostic trait distinguishing H. bicolor (127.0–134.4 kHz with a mean [x] of 131 kHz in Kingston et al., 2006 and 129.0–135.1 kHz, x = 132.1 kHz in Douangboubpha et al., 2010) and H. atrox (138.0–144.0 kHz, x = 141 kHz in Kingston et al., 2006 and 135.1–146.7 kHz, x = 142.3 kHz in Douangboubpha et al., 2010). However, echolocation calls recorded in the present study (F MAXE 133.0–138.4 kHz, x = 136.8 kHz, n = 7) are partially in the acoustic mid-space between H. bicolor and H. atrox. Based on molecular analyses, Khan (2013) concluded that the bicolor -group bat from Way Canguk Forest is the same species as H. bicolor (H. bicolor 131 kHz) from Central Java, Borneo, and Peninsular Malaysia (as H. bicolor - 2 in Khan, 2013, median values of F MAXE: 131–133 kHz), although echolocation data were unavailable for the Way Canguk bats in that study. In the present study, we tentatively assign all our bicolor -like bats as H. bicolor, as suggested by Khan (2013)., Published as part of Huang, Joe Chun-Chia, Jazdzyk, Elly Lestari, Nusalawo, Meyner, Maryanto, Ibnu, Maharadatunkamsi, Wiantoro, Sigit & Kingston, Tigga, 2014, A recent bat survey reveals Bukit Barisan Selatan Landscape as a chiropteran diversity hotspot in Sumatra, pp. 413-449 in Acta Chiropterologica 16 (2) on page 427, DOI: 10.3161/150811014X687369, http://zenodo.org/record/3943617, {"references":["ANDERSEN, K. 1918.

Myotis cf. borneoensis Hill and Francis, 1984 Bornean whiskered myotis New record New to Sumatra. Lampung Province: Way Canguk Forest. Remarks This is a medium-large brown Myotis species (FA = 45.8 mm) with wing membrane attached to the base of the toes. One adult male was collected by previous researchers from Gimbar 2 cave in Way Canguk Forest (MZB 35012). Comparing with known species on the Sunda Shelf, this bat most likely belongs to the montivagus species complex, which has not been recorded yet in Sumatra. Based on differences in forearm length and craniodental characters, Görföl et al. (2013) recognized four species in the montivagus species complex from Asia, including M. borneoensis, M. federatus, M. montivagus, and M. peytoni. Only M. borneoensis (Borneo) and M. federatus (Peninsular Malaysia) were reported from the Sunda Shelf, with M. montivagus known from South China and North Myanmar, and M. peytoni from India (Görföl et al., 2013). Our sample exhibits characteristics of each species except M. federatus, but we tentatively assign it to M. borneoensis based on cranial characters (separation between P 2 and P 4 and the length of the anteorbital bridge) and distribution. Further comparison and molecular analyses are necessary to clarify the taxonomic status of this species. In our study area, it can be easily identified from other known Myotis species by its larger forearm length., Published as part of Huang, Joe Chun-Chia, Jazdzyk, Elly Lestari, Nusalawo, Meyner, Maryanto, Ibnu, Maharadatunkamsi, Wiantoro, Sigit & Kingston, Tigga, 2014, A recent bat survey reveals Bukit Barisan Selatan Landscape as a chiropteran diversity hotspot in Sumatra, pp. 413-449 in Acta Chiropterologica 16 (2) on page 434, DOI: 10.3161/150811014X687369, http://zenodo.org/record/3943617, {"references":["GORFOL, T., P.

Glischropus sp. New record Lampung Province: Sukabanjar Forest. New material One individual was collected as a voucher specimen. Lampung Province: Sukabanjar Forest, 1♂ (MZB 35030). Remarks This was a small Pipistrellus -like bat (FA = 32.1 mm; BM = 4.8 g) caught with a harp trap adjacent to a small stream near the edge of disturbed forest at Sukabanjar at an elevation of 743 m a.s.l. The only known Glischropus species in Sumatra, G. tylopus, is smaller in forearm length (27.9–30.9 mm). Instead, the forearm length falls into the size range of G. bucephalus (FA = 32.1–35.7 mm) in Cambodia and is similar to G. javanus (FA = 32.0 mm) in Java (Csorba, 2011). The fur is dark gray basally with light brown tips on the upperparts, and the fur of the underparts is dark brown at the base and grayish brown to the tips. The cranial and external characters of this Glischropus are more similar to G. bucephalus than the other two species (G. Csorba, personal communication).

Chironax melanocephalus (Temminck, 1825) Black-capped fruit bat New records Lampung Province: Sukabanjar Forest, Sukaraja Forest, Way Canguk Forest.

Remarks Chironax melanocephalus was captured at an elevation of 50–855 m a.s.l. in lowland rainforest and disturbed forest in the survey area. Based on differences in cranial characters, fur color, and ear shape, Maharadatunkamsi (2012) recognized three subspecies of C. melanocephalus in Indonesia, (C. m. melanocephalus in Java and Sumatra, C. m. tumulus in Sulawesi, and C. m. dyasae in Kalimantan), and indicated that C. m. melanocephalus was the only subspecies in Sumatra. Nevertheless, two distinct morphological forms were found in this study. The first morph has round-tipped and shorter ears, smaller body size (Table 2), relatively weaker rostrum, and light gray or yellow underparts. The ear shape and rostrum are similar to those of C. m. melanocephalus and C. m. tumulus (as Pteropus melanocephalus in Temminck, 1825; Maharadatunkamsi, 2012) but the color differs on the underparts which is grayish brown in C. m. melanocephalus and brownish gray in C. m. tumulus. The second morph has triangular-tipped and longer ears, larger body size, a more robust rostrum, and is gray on the underparts. The ear shape and rostrum are more characteristic of C. m. dyasae but the color differs on the underparts which is yellowish brown in C. m. dyasae (Maharadatunkamsi, 2012).

Murina rozendaali Hill and Francis, 1984 Gilded tube-nosed bat New record New to Sumatra; Lampung Province: Way Canguk Forest. New material One bat was collected as a voucher specimen. Lampung Province: Way Canguk Forest, 1♂ (MZB 35884). Remarks One individual was caught with a harp trap in Way Canguk Forest. An additional sample of another male from Way Canguk Forest was found in the MZB (MZB 34991, FA = 30.9 mm), which is the first record from Sumatra. In the study area, M. rozendaali can be easily distinguished from other Murininae species by its smaller body size, except M. suilla. These two small Murina species can be distinguished by fur color and dental characters. Fur on the upperparts in M. rozendaali is dark brown at the base with shiny golden tips, differing from buffy/gray and orange-brown of M. suilla. The ratio of the crown area of the first upper premolar to the crown area of the second upper premolar is twothirds or more in M. rozendaali, but is half or less in M. suilla (G. Csorba, personal communication). Murina aenea is another species with similar coloration in the Sunda Shelf and has not been yet reported from Sumatra. The body size of M. rozendaali (FA 28–32 mm, BM 3.8–4.8 g) is smaller than M. aenea (FA 34–38 mm, BM 6.0– 8.5 g) and the underparts are white-based rather than buffy brown in M. aenea (Francis, 2008).

It was caught between 50–1014 m. a.s.l. in forests and coffee plantations One to two individuals were found roosting under a bed in a wooden house surrounded by mixed coffee plantations in Sukaraja Village for at least 13 months. In the study area, it can be easily distinguished from other Rhinolophus species, except R. lepidus / R. pusillus (see species account below), by its triangular-tipped connecting process, and then can be separated from R. lepidus / R. pusillus by its longer forearm., Published as part of Huang, Joe Chun-Chia, Jazdzyk, Elly Lestari, Nusalawo, Meyner, Maryanto, Ibnu, Maharadatunkamsi, Wiantoro, Sigit & Kingston, Tigga, 2014, A recent bat survey reveals Bukit Barisan Selatan Landscape as a chiropteran diversity hotspot in Sumatra, pp. 413-449 in Acta Chiropterologica 16 (2) on page 428, DOI: 10.3161/150811014X687369, http://zenodo.org/record/3943617, {"references":["VAN STRIEN, N.

Rhinolophus luctus Temminck, 1834 Woolly horseshoe bat New records Lampung Province: Sumber Rejo Village, Way Canguk Forest. New material Two bats were collected as voucher specimens. Lampung Province: Sumber Rejo Village, 2♂♂ (MZB 35808, 35809). Previous records from Sumatra North Sumatra (van Strien, 1996); Lampung Province: Krui (Sibuea and Herdimansyah, 1993). Remarks This was the largest Rhinolophus species in the study area (FA = 63.5 and 65.0 mm). Two adult males were captured with mist nets in a coffee plantation near the Way Pemerihan River in Sumber Rejo Village. An additional specimen in the MZB was collected by previous researchers from Way Canguk Forest (labeled as R. macrotis, MZB 35757)., Published as part of Huang, Joe Chun-Chia, Jazdzyk, Elly Lestari, Nusalawo, Meyner, Maryanto, Ibnu, Maharadatunkamsi, Wiantoro, Sigit & Kingston, Tigga, 2014, A recent bat survey reveals Bukit Barisan Selatan Landscape as a chiropteran diversity hotspot in Sumatra, pp. 413-449 in Acta Chiropterologica 16 (2) on page 430, DOI: 10.3161/150811014X687369, http://zenodo.org/record/3943617, {"references":["VAN STRIEN, N.

Myotis horsfieldii (Temminck, 1840) Horsfield’s myotis New records New to Sumatra; Lampung Province: Way Canguk Forest. New material Three individuals were collected as voucher specimens. Lampung Province: Way Canguk Forest, 1♂, 2♀♀ (MZB 35750–35752). Remarks It is a medium grayish-brown Myotis species (FA = 36.4–40.2 mm, n = 6) with wing membrane attached to the fifth metatarsal about 2 mm from the ankle. P 3 is completely inline with or partially lingual to the toothrow. The crown areas of P 3 and P 3 are one-third to two-thirds that of P 2 and the first lower premolar (P 2), respectively. Three individuals were captured flying low over a slow-moving section of the Way Canguk River. Additional records from Gimbar 2 cave in Way Canguk Forest were in the MZB (MZB 31484, 35013, 35014). In the study area, it can be distinguished from other known Myotis species by the wing attachment position. Comparing with all known Myotis species of the Sunda Shelf, the body size, wing attachment point, and dental characteristics are most comparable to that of M. horsfieldii (Bates and Harrison, 1997; Kingston et al., 2006), which has not been yet recorded from Sumatra (Simmons, 2005)., Published as part of Huang, Joe Chun-Chia, Jazdzyk, Elly Lestari, Nusalawo, Meyner, Maryanto, Ibnu, Maharadatunkamsi, Wiantoro, Sigit & Kingston, Tigga, 2014, A recent bat survey reveals Bukit Barisan Selatan Landscape as a chiropteran diversity hotspot in Sumatra, pp. 413-449 in Acta Chiropterologica 16 (2) on page 435, DOI: 10.3161/150811014X687369, http://zenodo.org/record/3943617, {"references":["BATES, P.
