Choerophryne is a genus of microhylid frogs, commonly known as Torricelli mountain frogs, endemic to New Guinea.[1] These frogs are small, with the body length measured from snout to vent between 11–23 mm.[2]

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.[2] Formal synonymisation of the two genera was suggested by Peloso and colleagues in 2016 based on molecular evidence.[3]

Etmology

The genus name of the junior synonym Albericus is the Latin form of Alberich, the shape-shifting dwarf in the epic poem Nibelungenlied.[4] Several species derive also their specific names from Nibelungenlied, e.g. C. siegfriedi from Siegfried and C. fafniri from Fafnir.[5]

Species

Amphibian Species of the World assigns 37 species to Choerophryne, including the species previously assigned to the genus Albericus:[1]
