CW146 has now been described by Tencatt et al. in 2022. Similar in appearance to CW111, but has a different colour pattern and is sympatric with this species in the Rio Curua, Rio Xingu drainage, Brazil. Lineage: Placed in Lineage 9, the "short-snouted" species with the designated type species: C. punctatus. A revision and a description in the future would constitute the resurrection of the genus name Hoplosopma (Agassiz, 1846). 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. Sexual Dimorphism: As well-documented in Corydoradinae (see Nijssen, Isbrücker, 1980b; Britto, 2003; Spadella et al., 2017), male specimens of C. thanatos present a genital papilla, which is somewhat tubular in shape. Aquarium male specimens eventually display a conspicuous elongation of the first and second dorsal-fin branched rays (Tencatt et al). Diet: Readily accepts a mixed and varied diet which includes granular foods, tablet food, frozen bloodworm and a good quality flake. Etymology: From the Greek thánatos, which means ?death?), the Greek god or personification of death, and the twin brother of Hypnos, the god/personification of sleep.
