[1] These frogs are small, with the body length measured from snout to vent between 11 and 23 mm.

[2] 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.

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

[3] 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.
