A. auteur aut IRD Durand Jean-Dominique auteur aut IRD text journalArticle eng text/pdf born digital access The taxonomic status of the keeled back mullets (Teleostei: Mugilidae) has been reinvestigated. Two nominal mugilid species having keeled backs from East Asia: Mugil lauvergnii Eydoux & Souleyet, 1850 and Mugil affinis Gunther, 1861 have been re-evaluated through examination of the holotypes and fresh specimens. Comparison of morpho-meristic characters of the holotypes shows that both species are identical. Phylogenetic analysis based on mitochondrial cytochrome c oxidase 1 (CO1) confirmed morphological data by highlighting presence of a single clade from East Asia. Mugil lauvergnii (=Planiliza lauvergnii) is thus the sole keeled back mullet from East Asia and a senior synonym of Mugil affinis (=Planiliza affinis). The taxonomic status of two other keeled back mullets, Planiliza carinata and P. klunzingeri, is also contentious due to their similar morphology. Meristic and morphometric variation as well as sequence divergence between the two species are limited but phylogenetic analyses delineate well-supported clades consistent with biogeography and currently accepted taxonomy. Planiliza carinata and P. klunzingeri share a recent common ancestor in a Maximum Likelihood tree, with separate distribution ranges while P. lauvergnii formed a paraphyletic lineage. Based on present findings, we suggest maintenance of the taxonomic distinction of P. klunzingeri and P. carinata and discuss its evolutionary significance. specialized COI sequencing Red Sea Persian Gulf Arabian Sea Mediterranean Sea GOLFE PERSIQUE MEDITERRANEE MER ROUGE 034 5194 4 497-518 2022 1175-5326 https://www.documentation.ird.fr/hor/fdi:010086395 10.11646/zootaxa.5194.4.2 1175-5326 [F B010086395] https://www.documentation.ird.fr/hor/fdi:010086395 https://www.documentation.ird.fr/intranet/publi/2022-12/010086395.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2022-12-09 2025-02-24 fdi:010086395 fre
