The relationships of the miniature genus Tucanoichthys are unknown. Tucanoichthys tucano Géry & Römer , its single species, has one row of eight conical premaxillary teeth, resembling some members of theAphyoditeinae or Characinae . The maxilla is completely toothed as in the Characinae , whereas the predorsal line is naked as in Gymnocorymbus (Tetragonopterinae) . Its coloration resembles that of Hyphessobrycon herbertaxelrodi , with a broad black lateral band dorsally delineated by a clear margin (Géry & Römer, 1997). The resemblance of this species to the Aphyoditeinae and the miniature genus Priocharax was mentioned in its description (Géry & Römer, 1997).
