Taxonomy
It was originally described as Callichthys splendens by François Louis de la Porte, comte de Castelnau in 1855. This species was once also commonly called Brochis coeruleus. W. A. Gosline was the first to suspect that the two species were the same in 1940, but it was actually Njiseen & Isbrücker in 1970 who combined the two, giving sufficient reasons for doing so.
Some believe that this species should be classified as Corydoras splendens and Brochis should be synonymized with Corydoras.
