Redefining Pareuchiloglanis

Post by Silurus »

Li, X, W Dao & W Zhou, 2022. Redefinition of the glyptosternine genus Pareuchiloglanis (Teleostei: Sisoridae), with descriptions of three new genera. Journal of Fish Biology doi:10.1111/jfb.15239.

Abstract

The genus Pareuchiloglanis (Sisoridae) contains 20 valid species and 5 species with uncertain taxonomic status. Previous morphological and molecular studies indicated that Pareuchiloglanis was non‐monophyletic; nonetheless, no change was made to correct the taxonomy of the genus. Therefore, the authors conducted a systematic morphological comparison and molecular phylogenetic study on Pareuchiloglanis. The results showed that Pareuchiloglanis is a polyphyletic group. Species previously identified as Pareuchiloglanis can be divided into four groups, of which Pareuchiloglanis poilanei alone has the genus name Pareuchiloglanis. The remaining three groups of species are contained within new genera named Barbeuchiloglanis, Sineuchiloglanis and Tremeuchiloglanis. Each genus has a distinct distribution that does not cross or overlap. The molecular results supported the reliability of morphological classification and indicated that the four genera were not directly related to one another. Specifically, Sineuchiloglanis and Tremeuchiloglanis shared no recent common ancestor. In contrast, Sineuchiloglanis formed a sister group with Chimarrichthys, and Tremeuchiloglanis formed a sister group with Creteuchiloglanis and Pseudexostoma.

If I could get a PDF of this work I will update the cat-eLog, or once it appears on a CoF update I will then eventually catch this.

Thanks for posting,
