The species that was known in the trade for many years under the name Corydoras xinguensis is in fact Hoplisoma albolineatum (Knaack, 2004). Also previously known under the C-number code of C056. The real Corydoras xinguensis, is a deeper bodied species, which has recently been imported into the UK (February 2007) from the Rio Xingu around Sâo Felix. Because of the variation in body markings it has received numerous C-numbers (C055, C105, C106, C107 and C108). 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 xinguiensis has now been placed in Lineage 9 and has the new genus name of Hoplisoma and also a change to the specific name to xinguense. 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. Remarks: This species is still found on some online sources as Corydoras xinguiensis.
