Similar looking to Brochis ambiacus (Lineage 8 sub clade 4) but has a very dark eye band compared to the latter's pale or nonexistent and H. leucomelas is a much smaller species and a shorter snout. The black blotch in the dorsal extends into the body. Lineage: Placed in Lineage 9, the "short-snouted" species with the designated type species: C. punctatus. A revision in the future would constitute the resurrection of the genus name Hoplisoma (Agassiz, 1846). As of the latest revision (Dias et al 2024) Corydoras leucomelas has now been placed in Lineage 9 and has the new genus name of Hoplisoma. Aquarium Care: This is akin to most of this genus, very peaceful, and would be best housed with small to medium sized tankmates such as Tetras, Rasboras and Danios or in a species tank for breeding purposes. Best to purchase 6 individuals or more as they will be happier in a group. Diet: Readily accepts a mixed and varied diet which includes granular foods, tablet food, frozen bloodworm and a good quality flake. Etymology: The specific name leucomelas: Meaning White and black. Remarks: Still found on some online sources as Corydoras leucomelas.
