A New Species

We here describe a new species of bent-toed geckos from the northeastern Indian state of Arunachal Pradesh, which is widespread across the Dafla and Mishmi hills, occurring at elevations ranging from 179 m to 1400 m. The new species is recovered as sister to the Cyrtodactylus khasiensis clade based on a molecular phylogeny inferred from mitochondrial NADH-ubiquinone oxidoreductase, subunit 2 gene. Intraspecific uncorrected pairwise sequence divergence (p-distance) for the new species was found to be between 0 and 5%, whereas the interspecific divergence from the closely-related congeners was between 19 and 30%. The new species can be differentiated from members of the C. khasiensis clade using a suite of morphological characters: moderate body size (SVL 64.9–81.7); 8–11 supralabials; 8–10 infralabials; 24–26 bluntly conical, feebly keeled dorsal tubercles; 50–60 paravertebral tubercles; ~38 ventral scales between ventrolateral folds; no precloacal groves; 6–10 precloacofemoral pores in a continuous series; 10–16 distal subdigital lamellae on IV of pes; subcaudal scalation of original tail without enlarged plates. This is the fourth reptile species described from Arunachal Pradesh from the expedition led by the team, and this further highlights the need for further herpetological investigations into the region.

A New Species

The first integrative taxonomic analysis of the Cyrtodactylus brevipalmatus group of Southeast Asia recovered two newly discovered populations from the Tenasserim Mountains in Suan Phueng District, Ratchaburi Province, Thailand as a new species described here as C. rukhadeva sp. nov. Based on 1397 base pairs of the mitochondrial gene NADH dehydrogenase subunit 2 (ND2), C. rukhadeva sp. nov. is the well-supported sister species to a clade containing three undescribed species, C. ngati, and C. cf. interdigitalis with a large uncorrected pairwise sequence divergence from other species in the brevipalmatus group ranging from 15.4–22.1%. Cyrtodactylus elok and C. brevipalmatus are recovered as poorly supported sister species and the well-supported sister lineage to the remainder of the brevipalmatus group. Cyrtodactylus rukhadeva sp. nov. is putatively diagnosable on the basis of a number of meristic characters and easily separated from the remaining species of the brevipalmatus group by a number of discrete morphological characters as well as its statistically significant wide separation in multivariate morphospace. The discovery of C. rukhadeva sp. nov. continues to underscore the unrealized herpetological diversity in the upland forests of the Tenasserim Mountains and that additional field work will undoubtedly result in the discovery of additional new species.

An integrative taxonomic analysis of the Cyrtodactylus linnwayensis group of the Shan Plateau recovered two new populations from isolated karst habitats near Pinlaung Town, Shan State as a new species, C. pinlaungensis sp. nov. Cyrtodactylus pinlaungensis sp. nov. is most closely related to a clade comprising C. linnwayensis and C. ywanganensis from the western edge of the Shan Plateau approximately 90 km to the northwest. Cyrtodactylus pinlaungensis sp. nov. can be distinguished from all members of the C. linnwayensis group by a number of statistically different morphological characters, discrete color pattern differences, and its heavy tuberculation. It also bears an uncorrected pairwise sequence divergence of 5.0–7.6% from all other species combined based on the mitochondrial gene ND2 and its flanking tRNAs. The discovery of this new species on the Shan Plateau continues to underscore the fact that this region is rapidly emerging as a herpetological diversity hot-spot for Myanmar.

A New Species

Abstract The potamid genus AcanthopotamonKemp, 1918 is known from three species, A. fungosum (Alcock, 1909), A. martensi (Wood-Mason, 1875) (type species), and A. panningi (Bott, 1966), and is found in Bangladesh, India, Nepal, and Pakistan. Within this range, the genus is found in the ‘Ganges Delta and Plain,’ ‘Lower and Middle Indus,’ and ‘Namuda-Tapi’ freshwater ecoregions. Here we describe a fourth species, A. horaisp. nov., from northeastern India (Arunachal Pradesh, Assam, and Mizoram) in the ‘Middle Brahmaputra’ and ‘Ganges Delta and Plain’ freshwater ecoregions. The new species possesses a unique suite of external and gonopod morphological characters, with the slender and narrowly conical terminal segment of the first male gonopod being particularly diagnostic. A key to the species of Acanthopotamon is provided.

We describe a new species of pitviper of the genus Atropoides from the Sierra de Botaderos and La Muralla, Honduras. The new species is easily distinguished from all other members of the genus, except A. picadoi from Costa Rica and Panama, by possessing more ventral scales (140 vs. 103–138). This new species differs from A. picadoi in being relatively small, less than 600 mm in total length (vs. reaching > 750 mm), having the posterior third of the body venter heavily melanized (vs. more than 50%), less than 50% of the underside of the tail melanized, and the postorbital stripe covering more than 50% of only one or two scales from the first temporal row and covering completely only the last scale of the row, at most (vs. 3–4 more than 50% melanized and the last two scales in the row usually completely melanized). In addition to morphological characters, molecular evidence also differentiates this new species from the other species of Atropoides (as recognized by Castoe et al. 2005). Using mitochondrial gene sequence data, they found the new species described herein to represent the sister species of A. occiduus, with 5.7 % sequence divergence separating these two taxa.

A new species of Megophryidae, Leptobrachium bompu is described from Eaglenest Wildlife Sanctuary, Arunachal Pradesh, India. It is a medium sized member of the genus Leptobrachium. In life, the frog is distinguished by the combination of a series of morphological characters from its congeners. Its entirely greyish-blue coloured eyes differentiate the species from all other species in the genus but Leptobrachium waysepuntiense. The morphological comparison is based on a table of 16 characters discriminant in Leptobrachium species.

A new species, Rubus haridasanii, from Arunachal Pradesh, Eastern Himalaya, is described and illustrated. It is closely related to Rubus preptanthus but differs by the presence of caudate-acuminate leaves, 5–6-flowered inflorescences, stipitate glandular pedicels and calyx, delicate needle-like prickles on the calyx, caudate apex of the sepals. The distinct foliar as well as floral morphology of R. haridasanii differ from all previously described species of Rubus. Differences in key morphological characters of R. haridasanii and R. preptanthus are also tabulated. In addition, pollen morphology is described based on light (LM) and scanning electron microscopy (SEM).

A new species of Nototriton is described from Refugio de Vida Silvestre Texiguat in northern Honduras, and is presented in a new phylogenetic hypothesis for the genus Nototriton. This species differs from all other congeners by a number of morphological characteristics, including but not limited to large nares, syndactylous hands and feet with pointed toe tips, and a pale ventral surface with light mottling. Mitochondrial sequence divergence distinguishes this species from all other Nototriton (3.6–6.0% at 16S and 10.2–15.1% at cytochrome b). Refugio de Vida Silvestre Texiguat harbors a remarkable herpetofauna, including 20% of all endemic amphibian and reptile species in Honduras, among which are five species (one anuran, one lizard, and three snakes) known only from the immediate vicinity of the type locality of the new species. Despite the evolutionary and conservation importance of this reserve, it remains one of the most imperiled cloud forests in Honduras due to persistent illegal logging and forest clearing.

A new species of Ansonia is described from the Shan Plateau of Myanmar based on an integrative taxonomic analysis that differentiates it from all other congeners. Molecular phylogenetic analyses based on the mitochondrial genes 12S and 16S rRNA and tRNA-val recover A. kyaiktiyoensis sp. nov. as the sister species to A. inthanon from Thailand but differs from it and other congeners by at least a 5.0% sequence divergence. It is further differentiated by the following combination of morphological characters: (1) maximum SVL 24 mm in males and females; (2) first finger shorter than second; (3) absence of interorbital and tarsal ridges; (4) presence of light-coloured interscapular spot; (5) presence of yellow rictal tubercle; (6) absence of wide, light-coloured patch below eye; (7) presence of large, discrete, bright-yellow submandibular spots along the underside of lower jaw; (8) iris yellow-gold; (9) presence of markings on the snout consisting of streaks below the eye to the lip, and on the canthus rostralis to the nostril; (10) dorsum grey-brown with orange-beige spots, a dark-brown X-shaped marking on the back surrounding the interscapular spot, and dark-coloured markings on rump; (11) fore- and hind limbs with orange-beige cross-bars; and (12) venter light-gray with yellow spotting, especially near flanks and underside of hind limbs. Ansonia kyaiktiyoensis sp. nov. is the westernmost known record for the genus and the only species west of the Salween Basin. Its discovery echoes the increasing number of herpetological discoveries being made in upland regions fringing the Ayeyarwady and Salween Basins.
