Megophrys (Xenophrys) zhangi Figures 1 and 3 (d – g); Tables 2, S 1, S 2 specimens examined: CMDN-A 48 – 49, 56 – 59, 64 – 66, 83 – 85, 87 – 88, 98 – 101, 104 – 118, 129 – 150, 154, 164 – 165, 167 – 170. Distribution in the KTM Valley: Encountered at all non-urban localities surveyed. Remarks: We encountered large numbers of Megophrys zhangi around the KTM Valley (Table 2; Figure 1). This species was traditionally classified as Megophrys parva until Chen et al. (2017) assigned several Megophrys species to Xenophrys, including M. parva. Alternatively, Mahony et al. (2017) classified Xenophrys as a subgenus of Megophrys which is the arrangement we favour in this manuscript. Our phylogenetic analyses revealed a close phylogenetic affinity between Megophrys parva from the KTM Valley and M. zhangi (Ye and Fei 1992) from the type locality (Figure 5). The type locality of M. zhangi is Zhangmu, Xizang, China, close to the Nepal-China border in the foothills of the Himalayas ~ 55 km from KTM Valley. However, Mahony et al. (2018) found that this M. zhangi individual (sequenced by Chen et al. 2017) shared an identical 16s haplotype with one of their two M. monticola haplotype groups from Darjeeling (‘ mid-elevation mitochondrial haplotype group ’). Using nuclear sequence data, Mahony et al. (2018) show that the two haplotype groups of M. monticola represent a single species that exhibit deep divergence with M. zhangi. Mahony et al. (2018) suggest that the shared haplotype may represent mitochondrial capture between these sister species. Thus, using 16s sequence we were unable to verify if the Nepalese sequences pertain to M. zhangi or M. monticola, though the geographic proximity to the M. zhangi type locality would support the former hypothesis. However, Mahony et al. (2018) differentiated M. zhangi (using the original description) from M. monticola based on a smaller SVL in the former. They state that in male specimens of M. zhangi (n = 3), SVL = 32.5 – 37.2 mm, compared with those of M. monticola (n = 17), SVL = 38.2 – 49.5 mm. SVL for the KTM Valley Megophrys range from 35 to 43.2 mm, overlapping the ranges given for the two species. However, the PCA of the 10 characters shared between our studies strongly separates the KTM Valley individuals from M. monticola, suggesting that the KTM Megophrys are on average much smaller (Figure 5 (b)). For this reason, we reclassify Megophrys parva from the KTM Valley to M. zhangi. Because we only sequenced specimens from the KTM Valley, we suggest that other Megophrys species may be present in other regions of Nepal outside of the KTM Valley (Mahony et al. 2018). Megophrys zhangi was encountered on the banks of streams and around areas with running water (Figure 3 (g)). While we usually observed them in intact habitats, they were also commonly encountered near disturbed areas with running water, but never in urban areas. Males called as early as 1600 during heavy rain but usually began calling at sundown (1900 in August). Females were found as far as 250 m from water, and always on the ground (Figure 3 (e)). Males perched ~ 1 m above the water when calling, and always faced the water. At each locality males utilised different perch taxa ranging from bushes, to large rocks, to man-made structures (Figure 3 (d,g)). This species was usually encountered in the same localities as Nanorana liebigii, but the two species were never observed in syntopy. At one locality in east Shivapuri, we encountered large numbers of larvae present in a shallow pool along with larvae and a juvenile of Duttaphrynus melanostictus (Figure 3 (f)). Measurements: The mean, followed by the range in parenthesis is given for males (n = 26), followed by females (n = 2). SVL = 39.2 mm (35 – 43.2 mm), 43.8 mm (40 – 47.8 mm); HL = 12.4 mm (10.0 – 14.8 mm), 13.0 mm (11.2 – 14.8 mm); HW = 14.9 mm (12.0 – 17.0 mm), 15.8 mm (14.9 – 16.6 mm); snout = 4.1 mm (3.3 – 5.7 mm), 4.2 mm (3.7 – 4.7 mm); internarial = 5.0 mm (3.8 – 5.8 mm), 4.65 mm (4.6 – 4.7 mm); eye = 3.5 mm (2.5 – 4.5 mm), 4.35 mm (3.9 – 4.8 mm); tympanum = 2.1 mm (1.7 – 2.7 mm), 2.6 mm (2.5 – 2.7 mm); antebrachium = 8.7 mm (7.1 – 10.2 mm), 8.1 mm (7 – 9.2 mm); hand = 10.5 mm (9.2 – 12.0 mm), 12 mm; thigh = 15.2 mm (13.5 – 17.5 mm), 14.5 mm (12.9 – 16.1 mm); shank = 16.8 mm (14.4 – 18.8), 17.1 mm (15.2 – 19 mm); foot = 27 mm (23.7 – 29.3 mm), 28.4 mm (27.6 – 29.1 mm)., Published as part of O, Kyle A., Connell, Aryal, Prakash C., Sherchan, Adarsh M., Dhakal, Bimala, Chaudhary, Hemanta Kumari, Ranabhat, Rishi & Karmacharya, Dibesh, 2019, A herpetological survey of the Kathmandu Valleyı Nepalı and phylogenetic identification of Megophrys (Xenophrys) zhangi, pp. 1421-1437 in Journal of Natural History 53 (23) on pages 1428-1431, DOI: 10.1080/00222933.2019.1655106, http://zenodo.org/record/3670114, {"references":["Chen JM, Zhou WW, Poyarkov NA, Stuart BL, Brown RM, Lathrop A, Wang YY, Yuan ZY, Jiang K, Hou M, et al. 2017.

Hoplobatrachus tigerinus Figures 1 and 3 (a – b); Table 2 specimens examined: CMDN-A 91 – 96, 156. Distribution in the KTM Valley: Encountered only in Lalitpur. Neither Pokhrel et al. (2011) or Aryal et al. (2013) encountered this species. Remarks: We observed large numbers of this species on the edge of an urban area. We encountered a large adult calling in a shallow pool on the edge of a village road in the vicinity of Microhyla, which were also calling (Figure 1; Figure 3 (b)). When approached, the frog raised its posterior end in a defensive position, as has been previously reported for this species (Anders 2002). We also observed large numbers of individuals in a wetland where males were calling (Figures 3 (a) and 4(d)). Several juveniles were also present at this locality, which probably represents common breeding habitat for this species in the KTM Valley., Published as part of O, Kyle A., Connell, Aryal, Prakash C., Sherchan, Adarsh M., Dhakal, Bimala, Chaudhary, Hemanta Kumari, Ranabhat, Rishi & Karmacharya, Dibesh, 2019, A herpetological survey of the Kathmandu Valleyı Nepalı and phylogenetic identification of Megophrys (Xenophrys) zhangi, pp. 1421-1437 in Journal of Natural History 53 (23) on page 1427, DOI: 10.1080/00222933.2019.1655106, http://zenodo.org/record/3670114, {"references":["Pokhrel GK, Aryal PC, Shah KB, Rjal B, Suwal MK, Kharel SC, Paudel E, Dhamala MK. 2011.

Fejervarya syhadrensis Figures 1 and 3 (f – h); Table 2 specimens examined: CMDN-A 17, 61, 68 – 70, 82. Distribution in the KTM Valley: Encountered at Godawari, Nagarkot, and Lalitpur. Pokhrel et al. (2011) and Aryal et al. (2013) reported this species from the whole KTM Valley, suggesting that it is widely distributed. Remarks: We encountered this species at three disturbed or urban localities, which is commonly the habitat used by species of this genus (Grosjean 2011). The first locality was in a livestock pasture, where large numbers of large-bodied larvae were present (Figures 2 (f) and 4(d)). At the second locality one adult was observed in grass near a large wetland in an urban area (Figure 2 (g)). At the third locality an adult was observed in thick grass near a large pond (Figure 1; Figure 2 (h)). Although past authors (e.g. Anders 2002) classified all Fejervarya from KTM as F. syhadrensis, sympatry and cryptic species in this genus are common, and further molecular work would help to confirm the species identity of all Fejervarya in KTM (Kotaki et al. 2009; Grosjean 2011)., Published as part of O, Kyle A., Connell, Aryal, Prakash C., Sherchan, Adarsh M., Dhakal, Bimala, Chaudhary, Hemanta Kumari, Ranabhat, Rishi & Karmacharya, Dibesh, 2019, A herpetological survey of the Kathmandu Valleyı Nepalı and phylogenetic identification of Megophrys (Xenophrys) zhangi, pp. 1421-1437 in Journal of Natural History 53 (23) on page 1427, DOI: 10.1080/00222933.2019.1655106, http://zenodo.org/record/3670114, {"references":["Pokhrel GK, Aryal PC, Shah KB, Rjal B, Suwal MK, Kharel SC, Paudel E, Dhamala MK. 2011.

Duttaphrynus melanostictis Figures 1 and 2 (a); Tables 2, S 1 specimens examined: CMDN-A 60 – 63, 97, 119 – 129, 151, 155, 172, 162. Distribution in the KTM Valley: Encountered in the periphery of Shivapuri-Nagarjun National Park, and Lalitpur. They have been previously reported from the southern part of KTM Valley (Aryal et al. 2013). Remarks: This species is common in disturbed and urban areas. At three sites we visited in the western part of the valley, this was the only amphibian or reptile species we encountered (Figures 1 and 2 (a)). We often found this species near areas with other human-commensals, but farther from the water. We also encountered this species on the eastern edge of Shivapuri-Nagarjun National Park. At this locality, we encountered larvae and one juvenile of this species syntopic with Megophrys zhangi larvae and adults. We used DNA barcoding to confirm the identity of the juvenile specimen (Table S2, phylogeny not shown).

Microhyla ornata Figures 1 and 3 (h); Table 2 specimens examined: CMDN-A 47, 138 – 139, 149 – 150. Distribution in the KTM Valley: Encountered in Lalitpur and Shreshnaryan, although Aryal et al. (2013) also encountered the species in north-western KTM Valley. Remarks: Microhyla were found at four sites around ponds or wetlands (Figure 1). Males were always encountered while calling, usually from under grass, about onehalf metre from the water (Figure 3 (h)). Larvae were usually present in large numbers in the water sources around which adults were calling. Recent work suggests that Nepal contains multiple species of Microhyla, and that the specimens encountered around KTM may belong to a related species, rather than M. ornata (Khatiwada et al. 2017). Molecular sequencing or in-depth morphological analysis would help resolve the taxonomic position of KTM Microhyla. Because we only encountered this species outside of national parks, we were unable to conduct further analyses (Figure 1)., Published as part of O, Kyle A., Connell, Aryal, Prakash C., Sherchan, Adarsh M., Dhakal, Bimala, Chaudhary, Hemanta Kumari, Ranabhat, Rishi & Karmacharya, Dibesh, 2019, A herpetological survey of the Kathmandu Valleyı Nepalı and phylogenetic identification of Megophrys (Xenophrys) zhangi, pp. 1421-1437 in Journal of Natural History 53 (23) on page 1431, DOI: 10.1080/00222933.2019.1655106, http://zenodo.org/record/3670114, {"references":["Aryal PC, Kharel SC, Bhurtel BP, Paudel EN, Dhamala MK, Rijal B, Thapa A. 2013.

- Abstract
Bengal tigers (Panthera tigris tigris) serve a pivotal role as an apex predator in forest ecosystems. To increase our knowledge on factors impacting the viability and health of this endangered species, we studied the gut microbiota in 32 individual Bengal tigers from three geographically separated areas (Chitwan National Park (CNP), Bardia National Park (BNP) and Suklaphanta Wildlife Reserve (SWR)) in Nepal, using noninvasive genetic sampling methods. Gut microbiota influence the immune system, impact various physiological functions, and modulates metabolic reactions, that ultimately impact the host health, behavior and development. Across the tiger populations in Nepal, we found significant differences in the composition of microbial communities based on their geographic locations. Specifically, we detected significant differences between CNP and the other two protected areas (CNP vs BNP: pseudo t = 1.944, P = 0.006; CNP vs SWR: pseudo t = 1.9942, P = 0.0071), but no differences between BNP and SWR. This mirrors what has been found for tiger gene flow in the same populations, suggesting gut microbiota composition and host gene flow may be linked. Furthermore, predictive metagenome functional content analysis (PICRUSt) revealed a higher functional enrichment and diversity for significant gut microbiota in the Chitwan tiger population and the lowest enrichment and diversity in Suklaphanta. The CNP tiger population contained higher proportions of microbiota that are associated with predicted functions relevant for metabolism of amino acid, lipid, xenobiotics biodegradation, terpenoides and polyketides than the SWR population. We conclude the tiger population structure, gut microbiota profile and associated functional metabolic categories are correlated, with geographically most separated CNP and SWR tiger population having the most distinct and different host genotype and microbiota profiles. Our work dramatically expands the understanding of tiger microbiota in wild

- Abstract
Tiger (Panthera tigris) populations are in danger across their entire range due to habitat loss, poaching and the demand for tiger parts. The Bengal tiger (Panthera tigris tigris) is an endangered apex predator with a population size estimated to be less than 200 in Nepal. In spite of strict wildlife protection laws, illegal trade of tiger parts is increasing; and Nepal has become one of the major sources and transit routes for poached wildlife parts. Identification of wildlife parts is often challenging for law enforcement officials due to inadequate training and lack of available tools. Here, we describe a molecular forensic approach to gain insight into illegally trafficked tiger parts seized across Nepal. We created Nepal’s first comprehensive reference genetic database of wild tigers through the Nepal Tiger Genome Project (2011–2013). This database has nuclear DNA microsatellite genotype and sex profiles, including geo-spatial information, of over 60% (n = 120) of the wild tigers of Nepal. We analyzed 15 putative cases of confiscated poached tiger parts and all were confirmed to be of tiger. Ten samples were identified as male and five were female. We determined probable geo-source location for 9 of the 14 samples with 6–8 nuclear DNA microsatellite loci using inferences from four different statistical assignment methods. Six samples were assigned to Bardia National Park and one of these was an exact match to a female tiger previously profiled in our fecal DNA reference database. Two tiger samples were assigned to Shuklaphanta Wildlife Reserve and one to Chitwan National Park. We are unable to definitively assign five tiger samples which could be offspring dispersers or might have come from tiger population outside of Nepal. Our study revealed that the western region, particularly Bardia National Park, is a poaching hotspot for illegal tiger trade in Nepal. We present feasibility of using molecular forensic based evidence to incriminate criminals in a court of

The herpetofauna of Nepal have been historically understudied, and although previous studies have reported on bioinventory surveys of the Kathmandu Valley, few have surveyed widely during the peak monsoon season. In addition, past studies largely neglected to survey intact forest habitats. Here we conduct a comprehensive field survey of the herpetofauna of the Kathmandu Valley, Nepal, with an emphasis on the surrounding foothills containing intact forest habitat. We record natural history and distribution data for seven species of amphibians and four species of reptiles. We also use mitochondrial sequence data to confirm the phylogenetic placement of two frog species, Megophrys (Xenophrys) parva and Duttaphrynus melanostictus. Using phylogenetic and morphological data we assign Megophrys parva from the Kathmandu Valley to Megophrys zhangi. We find that while this species shares a haplotype with its sister species, Megophrys monticola, morphological data align the individuals from the Kathmandu Valley with M. zhangi from Tibet. We find that M. zhangi exhibits no phylogenetic structure within the Kathmandu Valley, and wider sampling is needed throughout the Himalayas to determine its full range. These findings support the hypothesis that molecular sequence data will lead to the discovery of cryptic species in Nepal and facilitate the revision of species taxonomy. [ABSTRACT FROM AUTHOR]
