Description
Adult males measure 22–23 mm (0.87–0.91 in) and adult females 25–26 mm (0.98–1.02 in) in snout–vent length. The canthus rostralis is rounded and not distinct. The tympanum is barely visible. The fingers and the toes have well-developed terminal disks. The fingers have no webbing whereas the toes have sparse webbing. The dorsum is dark gray to gray-brown; there is a more or less distinct dark, W-like mark in the scapular region. A rusty hourglass-shaped marking, an inter-ocular bar, and a dark mark in the postocular-supratympanic region may be present. Black lumbar ocelli with white anterior edging are usually present. The groin and the thighs are yellow, sometimes with light gray mottling. The chin, chest, and abdomen are gray, sometimes almost black, with the chin darker than posteriorly, with tiny white flecks. The iris is grayish gold to dark gray-brown.
The male advertisement call is a series of 20–28 notes, with a dominant frequency of 2900–3200 Hz. The notes are uttered at a rate of 7–10 s−1, and the call lasts a few seconds.
