Abstract
A new species of the genus Euphlyctis is described from the Barisal district of Bangladesh and compared with its morphologically similar and geographically proximate congeners. The new species is highly divergent in comparison to other congeneric species on basis of sequence divergence in mitochondrial DNA gene sequences (ranging from 5.5% to 17.8% divergence). Euphlyctis kalasgramensis sp. nov. can be readily diagnosed by having the following combination of characters: snout-vent length (SVL) 30.44 - 37.88 mm, absence of mid-dorsal line, nostril-snout length 3% of SVL, nostril much closer to snout tip than eye, nostril-snout length 48% of distance from front of eyes to nostril, relative length of fingers (shortest to longest: 1 = 2 < 4 < 3), tibia length 59% of SVL, foot length 55% of SVL.
