Description
Males measure and females in snout–vent length. Male Micrixalus fuscus have a single vocal sac, a white patch on the lower jaw, and a prominent nuptial pad on the first finger. Characteristic for the genus, they display the "foot-flagging" behavior, where males tap their hindfeet and extend it, then stretching it out and shaking the foot at prospective mates and rival males. Male-male combats also involve kicking.Description from G. A. Boulenger's "Fauna of British India":
