Phylogeny: Campos-da-Paz (1999); Triques (2005); de Santana, Vari (2013, Apteronotus leptorhynchus group).

Remarks: The gender of Ubidia was not stated by Miles, and it has been listed as feminine in Mago-Leccia (1994), Eschmeyer (1998) and Eschmeyer et al. (2016). The name, however, is the surname of “señor Jorge Ubidia Betancourt ” and, as such, we believe the name should be treated as masculine.
