Adult males have an extended first dorsal fin ray. Similar to Hoplisoma parallelum but this species has an orange blotch in the predorsal region and the first ray of the dorsal is black whereas H. schwartzi has a transparent or greyish first dorsal fin ray followed by a black zone. 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 schwartzi 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 schwartzi: In honour of Hans-Willi Schwartz (1909–1981), aquarium-fish exporter in Manaus, Brazil, who helped collect holotype. Remarks: Still found on some online sources as Corydoras schwartzi.
