Description
Adult males measure {{convert|12|-|15|mm|abbr=on}} in snout–urostyle length; females are unknown. The snout is comparatively short (18–21% of the body length) and pointed. The eyes are relatively large. The tympanum is small. All fingers and toes bear discs. The overall ground colour is yellowish, greyish, or brownish, with brown, reddish or black markings and reticulations. Most specimens have an hour-glass marking on the dorsum, and many have a broad, light-coloured dorso-lateral stripe.[1]
The male advertisement call consists of two, sometimes only one, long and rasping notes. The notes have two phases; first with low and then with high pulse repetition rate. The dominant frequency in some calls is at 4.1 kHz, while others have two dominant frequencies (at 3.5 and 4.4 kHz).[1]

}}Habitat and ecology
At the type locality, Choerophryne amomani inhabits primary and secondary rain forest at elevations of {{convert|1050|–|1200|m|abbr=on}} above sea level. It was found to be locally common. Males call from on or in leaf litter, rarely slightly higher (to 0.3 m above the ground) in hollow plant stems.[1]
