Abstract
We present a new state record of Leptobrachella tamdil from Manipur State, northeastern India based on three individuals collected from Chakpi stream, Chandel District. This record represents the range extension of the species as well as the easternmost distribution record. We also provide additional morphological data as well as the first time genetic data for the species and inferred its phylogenetic position using mitochondrial 16S rRNA marker gene sequence.
Highlights
The collected specimens are identified as L. tamdil based on the original morphological diagnostic features (Sengupta et al 2010), and the new specimens showed genetic homogeneity on the phylogenetic tree with the mean intra-species K2P genetic distance of 0.0%
Our recently collected specimens are diagnosed in showing the following combination of characters: SVL between 27.8–28.7 mm in males and 33.2mm in the only female; dorsum tuberculate; eyelids with tubercles; tympanum and supratympanic fold distinct; supratympanic fold extending to posterior edge of tympanum; macroglands, including preaxillary, pectoral, femoral and ventrolateral glands present; Finger II > I; toe tips not dilated, bearing dermal fringes; relatively long hind limbs, with heels in contact when limbs are held perpendicular to body; dorsum with dark blotches; flanks with small dark blotches; dark tympanic mask present; venter pale; labial bars present and limbs with dark cross-bars (Sengupta et al 2010)
Tamdil (MW665130.1; MW665131.1; MW665132.1) were compared with the congeners sequences obtained from National Centre for Biotechnology Information (NCBI) database
Summary
On 16 December 2020, we encountered the first two adult male individual frogs (MZMU 2224 and MZMU 2225) from the Chakpi Stream bed (24.1454N, 93.5856E; 1,122m) at around 17.40h, the sampling site is located ca. The parameters from Sengupta et al (2010) and Vanlalsiammawii et al (2020) were followed to measure the frog specimens (Table 1).
