Brachyrhaphis

Brachyrhaphis is a genus of poeciliids native to freshwater habitats in Central America. Most are restricted to Panama and Costa Rica, but B. holdridgei also occurs in Nicaragua and B. hartwegi is from Mexico and Guatemala. A recent phylogenetic analysis has suggested that Brachyrhaphis may not be of a monophyletic group.
