What is "albericus"

Albericus is a genus of microhylid frogs endemic to New Guinea. These are small frogs with maximum body length around 27 mm. The genus was described in 1995, when three species in Cophixalus were separated as a new genus. The genus name Albericus is the Latin form of Alberich, shape-shifting dwarf in the epic poem Nibelungenlied. Several species derive also their specific names from Nibelungenlied, e.g. A. siegfriedi from Siegfried and A. fafniri from Fafnir.

The distinction between Albericus and the closely related genus Choerophryne is based solely on the orientation of the alary processes of the premaxillae, giving the latter 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.
