The Centromochlinae are a subfamily of the false spiny catfish (Auchenipteridae), to which almost 40 species belong. They only occur in South America .
features
The Centromochlinae are 3.5 to 19 cm long, depending on the species. The subfamily is diagnosed by three non- homoplasmic features . The anal fin of sexually mature males is transformed into a sperm-conducting, rearward-directed mating organ parallel to the spinal column, which consists of fin rays and the enlarged and wholly or partially fused proximal fin carriers (radialia), the partially ossified distal fin carriers and the long and thickened hemal arches of the adjacent hemispheres Vortex exists. The genital papilla develops from a flap of skin on the base of the anal fin. Males have three developed unbranched anal fin rays. The first is the shortest. It is about a quarter the length of the second and has fused segments (not in T. brunnea ). The second and third unbranched anal fin rays are thick. In some species there is a membranous keel immediately in front of the unbranched anal fin rays.
