This is a small species; adult standard length averages 19.8 mm in 10 males (range 18.2-21.7) and 20.6 mm in 10 females (range 18.1-22.0). The head is moderately wide; SL averages 7.2 times head width in males (range 6.2-8.7) and 7.6 times head width in females (range 7.0-8.3). Snouts are rounded to bluntly pointed. Nostrils are relatively large and elongate; the mean ratio of major axis to minor axis is 1.4 in males (range 1.2-1.6) and 1.5 in females (range 1.2-1.8). The eyes are somewhat protuberant and extend beyond the margin of the jaw in dorsal view, especially in males. A suborbital groove intersects the lip on each side of the head. The single cleared-and-stained specimen, a male, has two premaxillary teeth, six vomerine teeth, and no maxillary teeth. Limbs are relatively long; limb interval averages 3.5 mm in males (range 2.5-4) and 4.6 mm in females (range 4-5). Feet are relatively well developed. The middle two fingers and the middle three toes are much longer than the outer digits. Adjacent digits are free from one another only at their tips, which are rounded except in some smaller individuals in which they are slightly pointed. There are poorly developed subterminal pads on some of the larger specimens. The tail is relatively short and only rarely exceeds standard length; mean SL divided by tail length equals 1.23 in males (range 1.01-1.69) and 1.16 in females (range 0.99-1.32). The tail is round (in cross section) in smaller specimens, and quadrangular to somewhat laterally compressed in larger specimens. Coloration in life, based on field notes by J. Hanken for MVZ 182624-32: Most specimens have a greenish dorsal stripe (Hanken and Wake 1998).
