Abstract

Based on a molecular phylogeny using 16S ribosomal RNA gene fragment and an examination of the external morphology of topotypic specimens we demonstrate that Leptobrachella nokrekensis syn. nov. from Garo hills is a junior synonym of Leptobrachella khasiorum. These data indicate that Leptobrachella khasiorum which was previously considered restricted to the Khasi Hills and Critically Endangered is more widespread than previously known. Genetic evidences also suggests that L. tamdil from Lushai hills may also be conspecific with L. khasiorum, warranting further investigations. A reassessment of its threat status is required based on this taxonomic revision and the consequent extension of L. khasiorum’s distribution and elevational range.
