Changes.

Corydoradinae catfish are now split into 7 distinct genera, Corydoras,  Aspidoras,  Scleromystax,  Gastrodermus (resurrected),  Osteogaster (resurrected),  Brochis (resurrected), and Hoplisoma (resurrected).

As shown above, Gastrodermus, Osteogaster, Brochis, and Hoplisoma have in the past been recognised genus of these catfish, but over the years have been reclassified as Corydoras, now once again they are separate genera. The eagle-eyed may have noticed that Microcorydoras hasn’t made the list, instead the five recognised species in lineage 4 are now a part of Gastrodermus.

In this study, there are now 32 species of Corydoras. This is effectively Lineage 1, with an estimated 42 further species yet to be described.

Aspidoras hasn’t changed that much with 18 species here. Aspidoras rochai is the type species. This is lineage 2. There are 6 species estimated waiting to be described.

Schleromystax gets one new arrival, with Corydoras lacerdai moving in. Although I’ve always known it as Scleromystax lacerdai so this isn’t a great surprise. Scleromystax barbatus is the type species. This is Lineage 3 there are about 9 species waiting to be described in this lineage.
