A phylogenetic analysis of Hemibrycon determined its monophyly based on four synapomorphies: ectopterygoids with widened ventral anterior projection, four to six times wider than posterior part; a red spot present in life on ventral margin of caudal peduncle; a postero-ventral projection on the pterotic and first infraorbitals gradually decreasing in width from posterior tip and located near posterior part of antorbital (Arcila-Mesa 2008).
