Corydoras benattii (now Hoplisoma) is already known in the hobby under the code number C022 (Evers, 1994; Glaser et al., 1996; Evers & Schäfer, 2004; Füller & Evers, 2005). Colouration: Based on feld observations, photographs and aquarium specimens. Similar to preserved specimens but with ground colour of body greyish yellow. Region between antero-ventral margin of infraorbital 1 and lateral portion of mouth and between postero-ventral portion of infraorbital 1 and antero-ventral portion of opercle generally with conspicuously concentrated dark-brown or black chromatophores. Body covered by greenish yellow iridescent colouration (V.C. Espíndola et al.). 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 benattii 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 good quality flake. Etymology: The specific name benattii: honours the late Laert Benatti for his humanitarian work, providing fresh water from artesian wells to poor communities in Brazil. Case is genitive. Remarks: Similar to Hoplisoma cohcui Myers & Weitzmani, 1954, which for many years was considered to be the same species. This species is still found on some online sources as Corydoras benattii.
