This Hoplisoma was one of the first of the fleshy coloured, black banded/striped species with the gold markings to be collected in the tributaries of the upper Rio Negro in Brazil, alongside such species as Hoplisoma burgesssi  Hoplisoma davidsandsi and Brochis imitator which was collected at the same time and is basically the long nosed variety of C. adolfoi, and also the very similar Hoplisoma duplicareum which has a broader black band on the body and also a different structure to the pectoral fin spines. There has also been collections made over the border in Venezuela. 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 adolfoi has now been placed in Lineage 9 and has the new genus name of Hoplisoma. Aquarium Care: A tank setup would entail a soft substrate such as sand or a small gravel and a nice plant covering around the back and sides of the aquarium. If housed in a community tank a mixture of small South American characins or the smaller varieties of Asian Rasboras would suffice, as larger fishes would intimidate these shy Cory's, and would stop them eating and would be therefore detrimental to their overall health. Diet: A good quality flake food and tablet food for adults with sparodic feedings of frozen or live food will keep your Corydoras/Hoplisoma in good health. Etymology: The specific name adolfoi: in honour of aquarium-fish collector and exporter Adolfo Schwartz, Turkys Aquarium (Manaus, Brazil), who has been “a great help to TFH Publications in securing rare, interesting and unknown fishes”. Remarks: This species is still found on some online sources as Corydoras adolfoi.
