Old names, a new classification. The end of 𝐶𝑜𝑟𝑦𝑑𝑜𝑟𝑎𝑠 as we know it. Probably the biggest news in the world of Corydoradinae catfishes in 40 years! Luiz Tencatt and fellow researchers have just published a reconstructed phylogeny of the subfamily Corydoradinae. This revision resurrects historical names, with the result that the 𝐶𝑜𝑟𝑦𝑑𝑜𝑟𝑎𝑠 lineages are now to be split into separate genera, not least 𝐵𝑟𝑜𝑐ℎ𝑖𝑠 is back! Some 'new' names to learn for old friends! - 𝐶𝑜𝑟𝑦𝑑𝑜𝑟𝑎𝑠, 𝐴𝑠𝑝𝑖𝑑𝑜𝑟𝑎𝑠, 𝑆𝑐𝑙𝑒𝑟𝑜𝑚𝑦𝑠𝑡𝑎𝑥, 𝐺𝑎𝑠𝑡𝑟𝑜𝑑𝑒𝑟𝑚𝑢𝑠 (resurrected), 𝑂𝑠𝑡𝑒𝑜𝑔𝑎𝑠𝑡𝑒𝑟 (resurrected), 𝐵𝑟𝑜𝑐ℎ𝑖𝑠 (resurrected), and 𝐻𝑜𝑝𝑙𝑖𝑠𝑜𝑚𝑎 (resurrected). Follow up post due...

"Our results supported the monophyly of Corydoradinae and identified seven distinct groups of species, each one with an associated pre-available generic name. These genera, namely 𝐶𝑜𝑟𝑦𝑑𝑜𝑟𝑎𝑠, 𝐴𝑠𝑝𝑖𝑑𝑜𝑟𝑎𝑠, 𝑆𝑐𝑙𝑒𝑟𝑜𝑚𝑦𝑠𝑡𝑎𝑥, 𝐺𝑎𝑠𝑡𝑟𝑜𝑑𝑒𝑟𝑚𝑢𝑠 (resurrected), 𝑂𝑠𝑡𝑒𝑜𝑔𝑎𝑠𝑡𝑒𝑟 (resurrected), 𝐵𝑟𝑜𝑐ℎ𝑖𝑠 (resurrected), and 𝐻𝑜𝑝𝑙𝑖𝑠𝑜𝑚𝑎 (resurrected), were all validated based on evidence derived from molecular and morphological analyses. A taxonomic key for the Corydoradinae genera is provided."

The family Callichthyidae, which comprises the subfamilies Corydoradinae and Callichthyinae, represents one of the largest families within the Siluriformes.
Corydoradinae, the largest subfamily of Callichthyidae, alone accounts for >200 valid species, with new species being described frequently. This subfamily holds significant popularity among catfish enthusiasts worldwide, mainly because 𝐶𝑜𝑟𝑦𝑑𝑜𝑟𝑎𝑠 are small, peaceful, and colourful fishes. Recognizing the existence of polyphyletic groups within Corydoradinae, the aim of this study was to construct a new phylogenetic hypothesis using genomic data (ultraconserved elements) and to re-evaluate the synonymized genera using the most recent morphological data.
Our results supported the monophyly of Corydoradinae and identified seven distinct groups of species, each one with an associated pre-available generic name. These genera, namely 𝐶𝑜𝑟𝑦𝑑𝑜𝑟𝑎𝑠, 𝐴𝑠𝑝𝑖𝑑𝑜𝑟𝑎𝑠, 𝑆𝑐𝑙𝑒𝑟𝑜𝑚𝑦𝑠𝑡𝑎𝑥, 𝐺𝑎𝑠𝑡𝑟𝑜𝑑𝑒𝑟𝑚𝑢𝑠 (resurrected), 𝑂𝑠𝑡𝑒𝑜𝑔𝑎𝑠𝑡𝑒𝑟 (resurrected), 𝐵𝑟𝑜𝑐ℎ𝑖𝑠 (resurrected), and 𝐻𝑜𝑝𝑙𝑖𝑠𝑜𝑚𝑎 (resurrected), were all validated based on evidence derived from molecular and morphological analyses. A taxonomic key for the Corydoradinae genera is provided.
