Paleohoplias is an extinct genus of freshwater characin fish in the family Erythrinidae found in Brazil, South America. Two species are known.[2]
Taxonomy
The type species †Paleohoplias assisbrasiliensis Bocquentin & Negri, 2003 was described in 2003, and was found in the Solimões Formation in the State of Acre, Brazil, dating to the Huayqueriense-Montehermoseuse (Late Miocene-Pliocene) age.[1] A second species, †Paleohoplias amazonensis Decat et al, 2026 was described from the same formation in 2026.[2]
Etymology
The generic name Paleohoplias comes from the Greek palaios, which means "old", and hoplias, which is a closely related genus of fish in the same family, Erythrinidae. The species name assisbrasiliensis is in reference to the city of Assis Brasil, which is near the type locality.[1]
Classification
Paleohoplias is one of four genera within the family Erythrinidae, and the only extinct genus.[3] It is most closely related to the genus Hoplias.[1]
