Mammalia - Rodentia - Neoepiblemidae

Taxonomy

Phoberomys was named by Kraglievich (1926). It was considered monophyletic by Rasia and Candela (2018).

It was assigned to Eumegamyinae by Paula Couto (1956); and to Neoepiblemidae by Negri and Ferigolo (1999) and Rasia and Candela (2018).

Species

Dabbenea insolita, Dabbenea lozanoi, Dabbenea minima, P. bordasi, P. burmeisteri (syn. P. minima, Euphilus burmeisteri, P. lozanoi, P. praecursor, P. insolita), P. gyulavarii, P. pattersoni (syn. Dabbenea pattersoni)

Synonyms

Perumys was named by Kretzoi and Voros (1989).

It was synonymized subjectively with Phoberomys by Rasia and Candela (2018).

It was assigned to Neoepiblemidae by Kretzoi and Voros (1989).
Dabbenea was named by Kraglievich (1926). It is not extant.

It was synonymized subjectively with Phoberomys by Bondesio and Bocquentin Villanueva (1988).

It was assigned to Neoepiblemidae by Mones (1980); and to Dinomyidae by McKenna and Bell (1997).
