Body is covered with small spots and depending on the catchment area they can be vivid or pale. The upper part of the head is brown. Similar species are Hoplisoma polystictum and Hoplisoma sanchesi. 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 guianensis has now been placed in Lineage 9 and has the new genus name of Hoplisoma and a change to the specific name to guainense. 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 guianense: Named after the Guianas. Remarks: This species is still found on some online sources as Corydoras guianensis.
