Description

Adult males measure 23–29 mm (0.9–1.1 in) and adult females 28–37 mm (1.1–1.5 in) in snout–vent length.[4][5] Males have extremely long third fingers.[6] The tympanum is visible. The dorsum is greyish brown and bears small and large symmetrical dark brown blotches with a pale outline. There are three large blotches; the first one is triangular and starts between the eyes, pointing backwards. Another two blotches follow immediately behind.[2]

Habitat and conservation

Cardioglossa elegans occur in moist lowland and degraded forests at elevations below 1,000 m (3,300 ft). Breeding takes place in small streams, and males call from rocky areas or from under bridges.[1]

Cardioglossa elegans is a common species where it occurs, especially when aggregating for breeding. It can probably suffer locally from habitat loss. It is likely to occur in several protected areas.[1]
