CW141 has now been described by Tencatt et al. (2022) as Aspidoras aldebaran. Lineage: All Aspidoras belong to Lineage 2 and when there is a revision they will stay as Aspidoras von Ihering, 1907 with the type species of A. rochai Ihering, 1907. As of the latest update (Dias et al 2024), Aspidoras aldebaran has been placed in Lineage 2 and has retained the genus name of Aspidoras. Aquarium Care: Best kept in groups of six or more and are best housed with small fishes that are not aggressive. Although no plants occur in their habitat you can still provide a planted area in the tank for cover and include a soft substrate such as sand or small rounded gravel with coral sand added if in a soft water area. Diet: Flake, tablet foods, small live and frozen foods. Etymology: The epithet “aldebaran” refers to the red giant Aldebaran or Alpha Tauri (a Tauri), the brightest star of the Taurus constellation, deriving from the Arabic al Dabaran, which means “the follower”. The star presents a bright orange glow and it is positioned at the left eye of the mythological bull. The name alludes to the fact that Aspidoras aldebaran was firstly found among Aspidoras taurus type series, being promptly recognised as a different and new species by its peculiar morphology and colour pattern. A noun in apposition (Tencatt et al.). Remarks: As explained by Tencatt, Evers (2016:20), the C- and CW-number coding system was implemented by the fishkeeping hobby for putative new species to avoid the creation of nomina nuda in taxonomy. The species coded as CW141 is said to be from the same area as A. aldebaran, the Rio Araguaia basin at Alto Araguaia, Mato Grosso, and strikingly resembles the new species. Therefore, considering the clear compatibility between locality data and general morphology and colour pattern, we attribute CW141 to A. aldebaran, (Tencatt et al.).
