Corynopoma

Corynopoma is a monospecific genus of freshwater ray-finned fish belonging to the family Stevardiidae. The only species in the genus is Corynopoma riisei, the sword-tail characin, a species of characin found in Colombia, Trinidad and Tobago and Venezuela.

==Taxonomy== Corynopoma was first proposed as a genus in 1858 by the American biologist Theodore Gill when he described Corynopoma riisei. The type locality of C. riisei was given as Trinidad in Trinidad and Tobago. Gill named a number of species in the same publication, including species he classified in the genera Nematopoma and Stevardia; these are now regarded as synonyms of Corynopoma. However, Gill proposed a new subfamily he called Stevardianae, with Stevardia as its type genus, and thus this taxon is the type genus of the subfamily Stevardiinae. The family Stevardiidae is in the suborder Characoidei of the order Characiformes.
