Old names, a new classification. The end of ๐ถ๐๐๐ฆ๐๐๐๐๐ 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 ๐ถ๐๐๐ฆ๐๐๐๐๐ lineages are now to be split into separate genera, not least ๐ต๐๐๐โ๐๐ is back! Some 'new' names to learn for old friends! - ๐ถ๐๐๐ฆ๐๐๐๐๐ , ๐ด๐ ๐๐๐๐๐๐๐ , ๐๐๐๐๐๐๐๐ฆ๐ ๐ก๐๐ฅ, ๐บ๐๐ ๐ก๐๐๐๐๐๐๐ข๐ (resurrected), ๐๐ ๐ก๐๐๐๐๐ ๐ก๐๐ (resurrected), ๐ต๐๐๐โ๐๐ (resurrected), and ๐ป๐๐๐๐๐ ๐๐๐ (resurrected).

"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 ๐ถ๐๐๐ฆ๐๐๐๐๐ , ๐ด๐ ๐๐๐๐๐๐๐ , ๐๐๐๐๐๐๐๐ฆ๐ ๐ก๐๐ฅ, ๐บ๐๐ ๐ก๐๐๐๐๐๐๐ข๐ (resurrected), ๐๐ ๐ก๐๐๐๐๐ ๐ก๐๐ (resurrected), ๐ต๐๐๐โ๐๐ (resurrected), and ๐ป๐๐๐๐๐ ๐๐๐ (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 ๐ถ๐๐๐ฆ๐๐๐๐๐ 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 ๐ถ๐๐๐ฆ๐๐๐๐๐ , ๐ด๐ ๐๐๐๐๐๐๐ , ๐๐๐๐๐๐๐๐ฆ๐ ๐ก๐๐ฅ, ๐บ๐๐ ๐ก๐๐๐๐๐๐๐ข๐ (resurrected), ๐๐ ๐ก๐๐๐๐๐ ๐ก๐๐ (resurrected), ๐ต๐๐๐โ๐๐ (resurrected), and ๐ป๐๐๐๐๐ ๐๐๐ (resurrected), were all validated based on evidence derived from molecular and morphological analyses. A taxonomic key for the Corydoradinae genera is provided.
