Life History, Abundance, Activity, and Special Behaviors
The call consists of clicks very similar to that of H. endjami and H. acutirostris.

Like the similar H. acutirostris it breeds in small bodies of water in trees. Batches of eggs, 10–20 in number, are deposited just above water in the gelatinous jelly. After 13 to 20 days the tadpoles drop into the water.
