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.
