Putting European lampreys into perspective: A global?scale multilocus phylogeny with a proposal for a generic structure of the Petromyzontidae

Previous studies on the phylogenetic relationships between lamprey species relied either a low number of morphological characters related to feeding apparatus, or molecular mitochondrial DNA markers. Here, we apply multilocus approach assess northern hemisphere lampreys, with special emphasis 17 European species. The study comprises two (cytochrome c oxidase subunit 1 gene—DNA barcodes, and cytochrome b gene) nuclear (internal transcribed spacers I II) markers investigate species' affinities. phylogeny obtained revealed clear highly supported separation all lampreys. Among those, our results show several polyphyletic genera, stressing need for taxonomic revision in near future. Lampetra morii (Berg, 1931) from East Asia, often included Eudontomyzon, is placed genus Lethenteron. richardsoni Vladykov & Follett, 1965 Entosphenus hubbsi (Vladykov Kott, 1976) should be new genus, as well southern populations Lethenteron camtschaticum (Tilesius, 1811) reissneri (Dybowski, 1869). Considering species, argue Eudontomyzon vladykovi Oliva Zanandrea, 1959. Estudios anteriores sobre las relaciones filogenéticas entre especies de lampreas, se basan en un escaso número caracteres morfológicos relacionados con estructuras alimentación, o bajo marcadores moleculares ADN mitocondrial. Aquí aplicamos enfoque para evaluar lampreas del hemisferio norte, especial énfasis europeas. Este estudio comprende dos mitocondriales (citocromo oxidasa subunidad —ADN y citocromo b) nucleares (espaciadores transcritos internos II (ITS) ) investigar la afinidad filogenética especies. La filogenia obtenida losmarcadores reveló una separación clara altamente apoyada todas norte. Entre ellas, nuestros resultados muestran varios géneros polifiléticos, lo que resalta necesidad revisión taxonómica el futuro.
