As H. carlae is from Argentina a lower temperture as per the conditions for the Scleromystax species would probably suit this Hoplisoma. Similar pattern to the larger H. paleatum. 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 new revision is carried out. As of the latest revision (Dias et al 2024) Corydoras carlae 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 tank mates such as Tetras, Rasboras and Danios or in a species tank for breeding purposes. Diet: A good quality flake food and tablet food for adults with sporadic feedings of frozen or live food will keep your Corydoras in good health. Etymology: The specific epithet carlae is in honour of Carla Lindenaar-Sparrius, in charge of administrative duties for 11 years at the Zoölogisch Museum (Amsterdam) Department of Ichthyology (where the authors were curators of fishes). Remarks: Will sport yellow fins and barbels when in good condition. This species is still found on some online sources as Corydoras carlae.
