Type-species: Brochis coeruleus Cope, 1872 (=B. splendens).
See the Complete Catalogue for authorships, synonyms, type-localities,
and references.
Diagnosis
The genus Brochis is diagnosed by a reduced inner expansion of the second infraorbital bone; and by having 10-18 branched rays in the dorsal fin. This genus can be further distinguished from other callichthyids by the presence of small lateral cornua on the anterior tip of the mesethmoid.
Distribution
Brochis multiradiatus is apparently widely distributed in the Amazon basin, while Brochis britskii is found in the rio Paraguay system. Brochis splendens appears to dwell both in the Amazon and the Paraguay drainages.
