“…The tree revealed monophyly of each Hoplobatrachus species and the authors suggested that the environment specific to the river system (riverine delta region) has sustained the H. tigerinus population structure in this region. Kundu et al (2020) provided an updated distribution of H. litoralis in the Dampa Tiger Reserve, Mizoram state, northeast India, based on morphological and molecular data, where the BI phylogenetic tree revealed monophyly of five Hoplobatrachus species (H. crassus, H. tigerinus, H. litoralis, H. rugulosus, H. occipitalis) and a sister relationship was presented between H. litoralis and H. tigerinus. Nevertheless, Hoplobatrachus specimens from Myanmar (Bago and Yangon in Mulcahy et al, 2018) and Thailand were not included in the work of Kundu et al (2020).…”

Importance of the work: Northwestern Thailand lacks any intensive survey of amphibian fauna; thus, this area is suspected to have undiscovered populations of amphibians. Therefore, conducting field surveys in such areas is essential to fill knowledge gaps about species richness in this animal group. Objectives: To describe a new species of frog genus Hoplobatrachus as new to science. Materials & Methods: A new species was described based on specimens collected from Salawin National Park, Mae Sariang District, Mae Hong Son province, northwestern Thailand. The new species was separated from its congeners inferred from molecular (16S and Cytb genes) and morphological information. Results: The new species was distinguished from its congeners based on mitochondrial DNA sequence analyses and morphological comparisons. The species was characterized by the following characters: pointed snout; large size (snout-vent length [SVL] of adult males = 94.8-102.4 mm, SVL of females = 93.2-96.3 mm); presence of mid-dorsal stripe; absence of thin stripe on inner side of tibia; presence of sexual dichromatism; yellow external vocal sac; presence of nuptial pad on base of first finger in adult males; relative length of finger II < IV < I < III, toe I < II < V < III < IV. Main finding: A new frog species was described based on specimens from Thailand.

“…It has also been useful to understand the geographical distributions of populations, providing insights into the patterns of geneflow within a species (Hajibabaei et al 2007). Using DNA barcoding, many studies have identified the new extent of the species thus expanding their distribution range (Seshadri et al 2016;Kundu et al 2020;Lim et al 2020).…”

The frogs of genus Nyctibatrachus from the Western Ghats are endemic, with some taxa showing a narrow distribution range. Nyctibatrachus jog was known only from the type locality, Jog falls from Sharavathi river basin suggesting a restricted distribution. In this study, using DNA barcoding, we studied the distribution patterns of N. jog by sampling multiple river basins. 16S rRNA and Cytochrome b genes were used to distinguish N. jog from its congeners as well as to infer intra-species relationships. The results from the 16S rRNA gene showed 99% similarity of the collected individuals with the type specimen from Jog Falls confirming the identity of N. jog. The results indicate that N. jog has wide distribution extending its range in multiple river basins in the Western Ghats, India. This study also provides the Area of Occurrence and Extent of Occurrence of N. jog which could help in developing strategies for its conservation.

Herpetofauna is an important group of vertebrates with key functions in ecosystem sustenance. Nonetheless, with ever-increasing anthropogenic activities and lack of evidence-based studies, about 80% of the herpetofauna diversity of southern Asian region is threatened. Our study reports 80 herpetofauna species distributed across different habitat types in Dampa Tiger Reserve (DTR), Mizoram. We revise the amphibian list of DTR throughthe addition of seven species and establish the identity of cryptic species such as Microhyla ornata which is actually two distinct species,i.e., M. mukhlesuri and M. mymensinghensis. Through the questionnaire survey, it was found that 90% of the respondents depended on varied forms of forest resources. Herpetofaunal species account for 30% of the faunal resources with Varanus bengalensis, Ophiophagus hannah, and Python bivittatus being the most consumed reptile species. All chelonians and some amphibians like Duttaphrynus melanostictus, Pterorana khare, Hoplobatrachus tigerinus, Hoplobatrachus litoralis, Hydrophylax leptoglossa, Minervarya asmati, Polypedates teraiensis, and Sylvirana lacrima were also found to be consumed and used for their presumed medicinal values. In addition to hunting, road-kills, use of chemical pesticides, and habitat alteration were recorded to be the prominent threats in the region. The land use and land cover (LULC) data shows a steady recovery of dense forest and a better forest fire scenario as over 90% of the DTR core region falls in the ‘low severity’ and ‘unburned’ category. With continuous alteration in forested areas, the present study will not only provide a fundamental baseline for the conservation of herpetofauna and better management of protected areas but also stimulate future herpetological-based research.
