Adult males measure in snout–vent length. An adult female measures , whereas a female measuring 22 mm appears to be a sub-adult. The head is broader than it is long; the snout is tapering and projecting. The
tympanum is covered by skin and barely visible. The fingers and toes have discs with circummarginal grooves. The colouration is dorsally beige (sometimes greyish-brown) with some spots and marbling. About one half of animals have a conspicuous whitish mid-dorsal line that has blackish borders, and similarly many have a W-shaped mark in the scapular area, surrounding two whitish spots. The throat is black (hence the
specific name atrigularis, from Latin
ater for "black" and
gularis for "belonging to throat") grading posteriorly into dark brown or dark grey marbling; the female and one male have pale grey throat. Males have a single internal subgular
vocal sac. ==Habitat and conservation==
