True for different genera, but here we are dealing with something a bit different. Just for interest sake, I will digress and summarize what may be of interest to some.
It has been proposed by more than one ichthyologist that the three genera currently in the Corydoradinae
subfamily of the family Callichthyidae
need revision, and some has already occurred. Four cory species have been moved by M.R. Britto into a new genus, Scleromystax
, and you can read about this in our profile of Scleromystax barbatus
, previously Corydoras barbatus
. This proposal has been officially accepted by the scientific community.
Britto also proposed the elimination of the genus Brochis
in his 2003 paper "Phylogeny of the subfamily Corydoradinae
Hoedeman, 1952 (Siluriformes: Callichthyidae), with a definition of its genera," in the Proceedings of the Academy of Natural Sciences of Philadelphia. Ferraris (2007) accepts this, and in his checklist of the catfish of South America gives the three "Brochis" species as Corydoras
. The California Academy of Science has not yet followed this, and they are usually the definitive word on current names.
Anyway, what is clearly apparent is the very close relationship between the species in Corydoras
; according to Britto's findings there are no differences between these species, whatever we may call them, that justifies distinct species differentiation. No one has yet proven this hypothesis inaccurate, so expect name changes at some point.
By the way, Britto has also proposed moving several species out of Corydoras and into Aspidoras, another genus of very near-identical "cory" like catfish.
