Description: Adults range between 62 to 142 mm in total length (males 58-65 mm standard length, females 34-72 mm standard length). The tail is moderately long, ranging from 49 to 52% of total length. Has 13 costal grooves (based on Dundee's visual count of costal grooves visible in Vial's original figure). Adult males have 0 to 0.5 costal folds separating adpressed limbs, while adult females have 0 to 1 costal folds separating adpressed limbs. Maxillary teeth range from 43 to 79, and vomerine teeth range from 22 to 33 in adults. The snout is blunt and rounded, with conspicuous nostrils and nasal cirri. Limbs are long and slender; when appressed to the body, they meet or overlap by up to a single costal fold. Hands and feet have moderate webbing (3/4) with two phalanges free of web on longest digits. Digits are flattened with rounded tips and have slightly developed subterminal pads (Dundee 1997; Savage 2002).
Coloration in life: Dorsal surfaces are dark lavender brown with many minute yellow flecks, particularly along the lateral margins of the body. The dorsal surface of the tail has a uniform dark lavender brown ground color with light blotches. The gular region is washed with lavender brown (uniform or marked with light blotches) (Dundee 1997).
