Brochis is a genus of catfish in the subfamily Corydoradinae, family Callichthyidae of the order Siluriformes. Before the recent resurrection of the genus, these species have been grouped in the genus Corydoras .

Taxonomy

Brochis was erected by Edward Drinker Cope on 1871. Before 2024, it was in a limbo and considered defunct by most scientific authorities, [1] being considered as a junior synonym or subgenus of Corydoras. [2] It was formally resurrected and revalidated in a phylogenomic analysis carried out in 2024. [3] B. difluviatilis is recognized as the basalmost species of Corydoradini, exhibiting several plesiomorphic features compared to the other species of Corydoras. [2] [4]

Etymology

The generic name, Brochis, is derived from the Greek βρόχος meaning loop, referring to the diagnostic arrangement of the barbels around the mouth. [5]

Morphology

Despite being considered defunct, there are several morphological features that validate the usage of Brochis as a genus. These include a noticeably larger body, a more lyre-like tail and most decisively, the extended dorsal fins that have more rays than those of Corydoras. [6] Corydoras have 7-10 rays on their dorsal fins, while Brochis have 10–18. [7] Brochis are very large for their family, as several species can breach 8 centimetres (3.1 in) in length. Brochis splendens is the largest, attaining a maximum size of 9.9 centimetres (3.9 in) and 40 g (1.4 oz). [8]

Species

As of August 2025, there are currently 43 extant species in this genus (as recognized by Eschmeyer's Catalog of Fishes), [9]
