Description

Adult males measure around 27–31 mm (1.1–1.2 in) and adult females 32–35 mm (1.3–1.4 in) in snout–vent length. They have a light and dark brown dorsal pattern that normally include a rectangular dark dorsal spot and which extends to the anus. Males have small, scattered, and inconspicuous asperities on the dorsal surfaces of head, body, and limbs. The tibia have light upper side.[3]

The male advertisement call consists of a series of clicks emitted at a rate of 18–30 per second.[3]

Habitat and conservation

Afrixalus osorioi occurs in degraded secondary forests and heavily degraded former forests (including farm bush) of the central African rainforest belt. Breeding takes place in small temporary and permanent water bodies with overhanging vegetation. They also use artificial water bodies such as old drums. It is an abundant and adaptable species that is unlikely to face significant threats. It occurs in several protected areas.[1]
