Oligobrycon Eigenmann, 1915 View in CoL
Oligobrycon was included in the Aphyoditeina by Géry (1977) by sharing some characters that are actually broadly distributed in Characidae (e. g. compressed body, adipose fin present, dorsal fin without dark markings). Géry stated in the identification key of the Aphyoditeina that O. microstomus Eigenmann has strong but not compressed teeth and only four teeth in the premaxilla. One of the synapomorphies of the Aphyoditeinae is the presence of eight or more slender premaxillary teeth in a single row; thus, this species is maintained as incertae sedis.
