frogs, commonly known as Torricelli mountain frogs, endemic to New Guinea. These frogs are small, with the body length measured from snout to vent between 11 and 23 mm.

Taxonomy and systematics

The distinction between ''Choerophryne'' and the former genus ''Albericus'' was based solely on the orientation of the alary processes of the premaxillae, giving the former its distinctive snout. In 2013 a new ''Choerophryne'' species was described with an orientation intermediate between the two genera, suggesting ''Albericus'' is likely a junior synonym of ''Choerophryne''. Formal synonymisation of the two genera was suggested by Peloso and colleagues in 2016 based on molecular evidence.

Etymology

The genus name of the junior synonym ''Albericus'' is the Latin form of Alberich, the shape-shifting dwarf in the epic poem Nibelungenlied. Several species derive also their specific names from Nibelungenlied, e.g. ''C. siegfriedi'' from Siegfried and ''C. fafniri'' from Fafnir.
