Members of the genus Nyctibatrachus are robust-bodied frogs that range in size from small (snout–vent length <13 mm in Nyctibatrachus robinmoorei)[5] to relatively large (up to 84 mm Nyctibatrachus karnatakaensis). The especially small species are among the smallest of all Indian frogs.[4] They have a concealed tympanum, dorsum with longitudinal skin folds, femoral glands, and expanded finger and toes disks. They occur near streams in hilly evergreen forests[6] and are nocturnal.[7] Most species have amplexus but Nyctibatrachus humayuni does not; in this species the male moves over the eggs after the female has deposited them.[6]
The following species are recognised in the genus Nyctibatrachus:[1]
