Osteogaster is a genus of catfish in the subfamily Corydoradinae, family Callichthyidae of the order Siluriformes. Before the recent resurrection of the genus, these species had been grouped in the genus Corydoras.
Osteogaster was erected by Edward Drinker Cope in 1894. Before 2024, it was considered defunct by most scientific authorities, being considered as a junior synonym or subgenus of Corydoras.[1] It was formally resurrected and revalidated in a phylogenomic analysis carried out in 2024.[2]
Etymology
The generic name, Osteogaster, is derived from the Greek ὀστέον, ostéon, meaning "bone:, and γαστήρ, gastḗr, meaning "belly", referring to the coracoid bones of O. eques which completely enclose the ventral region.[3]
