- Abstract: Previous studies on the phylogenetic relationships between lamprey species relied either on a low number of morphological characters related to the feeding apparatus, or on a low number of molecular mitochondrial DNA markers. Here, we apply a multilocus approach to assess the phylogenetic relationships of northern hemisphere lampreys, with a special emphasis on the 17 European species. The study comprises two mitochondrial ( cytochrome c oxidase subunit 1 gene—DNA barcodes, and cytochrome b gene) and two nuclear ( internal transcribed spacers I and II ) markers to investigate species' phylogenetic affinities. The phylogeny obtained with mitochondrial markers revealed a clear and highly supported separation of all northern hemisphere lampreys. Among those, our multilocus results show several polyphyletic genera, stressing the need for a taxonomic revision in a near future. Lampetra morii (Berg, 1931) from East Asia, often included in Eudontomyzon, is placed in the genus Lethenteron . Lampetra richardsoni Vladykov & Follett, 1965 and Entosphenus hubbsi (Vladykov & Kott, 1976) should be placed in a new genus, as well as the southern populations of Lethenteron camtschaticum (Tilesius, 1811) and Lethenteron reissneri (Dybowski, 1869). Considering European species, our results argue for a taxonomic revision of Eudontomyzon, with emphasis on Eudontomyzon vladykovi Oliva & Zanandrea, 1959.

Resumen: Estudios anteriores sobre las relaciones filogenéticas entre especies de lampreas, se basan en un escaso número de caracteres morfológicos relacionados con las estructuras de alimentación, o en un bajo número de marcadores moleculares de ADN mitocondrial. Aquí aplicamos un enfoque multilocus para evaluar las relaciones filogenéticas de las lampreas del hemisferio norte, con especial énfasis en 17 especies europeas. Este estudio comprende dos marcadores mitocondriales ( citocromo oxidasa c subunidad 1 —ADN barcodes, y citocromo oxidasa b ) y dos marcadores nucleares ( espaciadores transcritos internos I y II (ITS) ) para investigar la afinidad filogenética de las especies. La filogenia obtenida con losmarcadores mitocondriales reveló una separación clara y altamente apoyada de todas las lampreas del hemisferio norte. Entre ellas, nuestros resultados multilocus muestran varios géneros polifiléticos, lo que resalta la necesidad de una revisión taxonómica en el futuro. Lampetra morii (Berg, 1931) de Asia oriental, a menudo incluida en Eudontomyzon, se sitúa en el género Lethenteron . Lampetra richardsoni Vladykov & Follett, 1965 y Entosphenus hubbsi (Vladykov & Kott, 1976) deben colocarse en un nuevo género, así como las poblaciones meridionales de Lethenteron camtschaticum (Tilesius, 1811) y Lethenteron reissneri (Dybowski, 1869). Considerando las especies europeas, nuestros resultados abogan por una revisión taxonómica de Eudontomyzon, con énfasis en Eudontomyzon vladykovi Oliva & Zanandrea, 1959. … (more)
