Hyloxalus aeruginosus

Hyloxalus aeruginosus is a poorly-known species of rocket frog inhabiting the cloud forests in the Andes, in western Peru. Very little is known about the species; its reproductive habits and tadpole classification are unknown. Even the species' population trend remains a mystery.

The species is dimorphic; with the "nominal" morph being black laterally with a white stripe running from the jaw to the front legs, a deep brown dorsally, and off-white ventrally. A second, smaller morph is known and is almost exclusively grey-green, flecked with pale blue along the flanks.

Due to lack of substantial knowledge of the species, its small and remote range, and the elusive nature of the species itself, H. aeruginosus is currently absent from the frogkeeping hobby.
