Taxonomy

Hoplisoma was first proposed as a genus in 1838 by the English naturalist William Swainson with Cataphractus punctatus, a species described in 1784 by Marcus Elieser Bloch from Suriname, as its only species and designated as its type species by Swainson. [1] [2] For a long period this taxon was regarded as a synonym of Corydoras but it was resurrected as a valid genus by a phylogenomic analysis published in 2025. [3] This genus is classified in the subfamily Corydoradinae of the armoured catfish family Callichtyidae in the suborder Loricarioidei in the catfish order Siluriformes. [4]

Etymology

Hoplisoma combines holpon, meaning "shield" or "armour", with soma, which means "body", a reference to the bony scutes on the flanks of these fishes. [5]

Species

Hoplisoma contains the following valid species: [2]
