Color is brown to grey having small spots. Tongueless, tapered heads. Eyes lidless, circular, and flat. Long-legged, claws on rear feet. Looks simliar to H. curtipes but H. curtipes has wartier skin. Females reach a larger size than males (up to 35 mm), have a longer tail and also have a more stout abdominal region. The posteriorlateral portion on the head of a male has a swollen appearance due to a large orbiculate tympanum (2.5 mm). Orbiculate tympanus in males is twice as large as in females. Males also have a post axillary subdermal gland which appears as a whitish spot on the surface of the skin. The post-axillary subdermal gland is located on the back of the front leg. The gland enlarges during periods of sexual activity. Females lay eggs with a diamter of about 1.3 mm (Rabb 1963).
Tadpoles have spinose tubercules on the sides of thigh. Silvery iridocytes on a gray dorsum and a weakly pigmented tail. The iridocytes may be golden or silver. The tail has a longitudinal arrangement of dark coloration where melanophores surround the aorta, caudal vein, and the top and bottom of the caudal musculature. Golden iridocytes are also found on the top of the caudal muscles. The tail fin is pigmentless (Rabb 1963).
