Relevant Information:

Description: Corydoras gladysae (now Hoplisoma gladysae) is distinguished from other species of the genus by the caudal-fin shape, slightly emarginated and by presenting the shortest dorsal and pectoral spines length (mean = 9.2 % and 14.8 % of SL, respectively). This Corydoras (Hoplisoma) species is similar looking to the Aspidoras genus and in the future may be moved into this genera. Habitat: Currently, the species is only known from Calchaquí river, in the sub-Andean range system, at Cachi and Payogasta localities, in Cachi Department, Salta, Argentina. This river is a tributary to the superior river basin of the Juramento river, that ends in Paraná river. 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 gladysae 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 epithet refers to and is dedicated to its original collector Gladys Ana María Monasterio de Gonzo. Remarks: Coming from the southern parts of South America this species prefers the water temperature to be more on the cooler side. This species is still found on some online sources as Corydoras gladysae.
