The spelling of the generic name has been confused; it is currently valid as Conorhynchos as described by Pieter Bleeker in 1858.[1] This catfish has unknown relationships. It does not appear to be assignable to any family and is placed incertae sedis.[1] However, it has been grouped into the superfamily Pimelodoidea due to molecular evidence.[2]

Conorhynchos conirostris is endemic to the São Francisco River in Brazil and is considered a symbol of the river.[3] This fish can reach 53.5 centimetres (21.1 in) in standard length[4] and 13 kilograms (29 lb) in weight.[3] This fish is of commercial interest,[3] and is considered threatened by Brazil's Ministry of the Environment.[5]
