Nyctibatrachus is a genus of frogs endemic to the Western Ghats of southwestern India. Their common name is night frogs.[1][2] Their scientific name also means "night frog", in reference to their habits and dark color.


Nyctibatrachus are robust-bodied frogs that range in size from small (snout–vent length <13 mm in Nyctibatrachus robinmoorei)[3] to relatively large (up to 84 mm Nyctibatrachus karnatakaensis). 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[4] and are nocturnal.[5] Most species have amplexus but Nyctibatrachus humayuni does not; in this species the male moves over the eggs after the female has deposited them.[4]
