Scissor Günther, 1864

This monotypic genus was described from a single specimen of uncertain origin, although it is supposed that it is from Suriname (Lima et al., 2003).According to Eigenmann (1917) this specimen has short gill-rakers, 29 anal-fin rays, conical teeth distributed along one half of the maxillary length, andpremaxillaryanddentary teeth similar to those of Tetragonopterus . Géry (1977) included Scissor macrocephalus Günther in his tribe Bramocharacini .The available information, as evident, is not sufficient to propose the inclusion of this genus in any of the clades herein proposed.
