Description

This is a small species; adult standard length averages 18.3 mm in 10 males (range 16.6-20.8) and 17.8 mm in 4 females (range 16.7-19.2). The head is relatively broad; SL averages 6.7 times head width in males (range 6.0-7.6), 6.5 times head width in females (range 6.0-7.1). Snouts are relatively broad and blunt in females and more pointed in males. Nostrils are relatively large and nearly round; the mean ratio of major axis to minor axis equals 1.1 in both males (range 1.0-1.2) and females (range 1.0-1.1). Eyes are moderately sized and protrude slightly beyond the margin of the head in ventral view. A suborbital groove intersects the lip on each side of the head. The two males each have a single premaxillary tooth, 4-5 vomerine teeth, and no maxillary teeth. There were no cleared-and-stained female specimens on which to count teeth. Limbs are relatively long and slender; limb interval averages 3.4 in males (range 2-4) and 3.8 in females (range 3-4). Hands and feet are narrow; the third finger and toe are substantially longer than remaining digits and are sharply pointed. Fingers, in order of decreasing length, are 3-2-4-1; toes are 3-4-2-5-1. The tail is relatively long; mean SL divided by tail length equals 0.68 in males (range 0.64-0.80) and 0.72 in females (range 0.67-0.76). The mental gland is round to ovoid. The postiliac gland is obscure (Hanken and Wake 1998).
