Adult Size

In terms of body size, male Ansonia leptopus measure 30–40 mm (1.2–1.6 in) in snout–vent length, while females can reach up to 55 mm (2.2 in) in this measurement.

Dorsal and Mandible Features

The dorsum of this species is covered in low warts, and individuals have brown or yellow spines under the mandible.

Tadpole Size and Coloration

The tadpoles of Ansonia leptopus are small, measuring less than 20 mm (0.79 in), and have distinctive black markings over a light-colored background.

Tadpole Oral Sucker

Their oral sucker is less well-developed than that of tadpoles of other species in the Ansonia genus.

Natural Habitat

This species lives in primary rainforest as its natural habitat.

Adult Distribution in Habitat

Adult Ansonia leptopus are widely spread across the forest floor and herb layer.

Male Calling Site

At night, calling males can be found resting on boulders and rocks along river banks.

Breeding Location and Type

Breeding is explosive, and occurs in small, clear, rocky-bottomed streams.

Tadpole Microhabitat

Tadpoles are most frequently found in shallow side pools and submerged dead leaf beds.

Threats

Ansonia leptopus is threatened by habitat loss caused by deforestation, which also leads to siltation of the streams the species uses for breeding.
