C. flaveolus (now Hoplisoma flaveolum) is rare in imports from the headwaters of the Sierra Piracicaba. Lineage: Placed in Lineage 6 which has always been classified as Corydoras (Lacépède, 1803) so a new genus would need to be described and a new type species when a revision is carried out. As of the latest revision (Dias et al 2024), Corydoras flaveolus has now been placed in Lineage 9 and has the new genus name of Hoplisoma and a change to the specific name to flaveolum. 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 flaveolum: Latin for yellowish, referring to the “yellowish” body colour. Remarks: This species is still found on some online sources as Corydoras flaveolus.
