Dusky torrent frog, Brown tropical frog
Micrixalus fuscus (dusky torrent frog or brown tropical frog) is a species of small frog found in dense forested hill streams in the Western Ghats of India. M. herrei was formerly synonymized within this species.
Males measure 27.9–28.8 mm (1.10–1.13 in) and females 30.0–33.1 mm (1.18–1.30 in) 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 (1890) "Fauna of British India":
The natural habitats of this species are fast-flowing streams covered by forest canopy. It is relatively abundant where it has been found.
