The taxonomic status of Neoechinorhynchus agilis s. l. from grey mullets was<br>recently reviewed that resulted in description of two new species, Neoechinorhynchus (Hebesoma) personatus<br>and Neoechinorhynchus (Hebesoma) yamagutii. In the current study,18S rRNA partial gene sequences<br>were obtained to molecularly characterize N. (N.) agilis, N. (H.) personatus and N. (H.) yamagutii<br>from grey mullets, Chelonlabrosus and Mugil cephalus, in the North-East Atlantic, the Japan, Azov and<br>Mediterranean Seas. The universal (F-566 and R-1200) and specific eukaryotic set primers were used to<br>amplify specimens from each species of Neoechinorhynchus. It has been found that three species can be<br>clearly recognized using universal primers, which allow to obtain sequences of 590 to 664 bp in length.<br>The genetic divergences estimated between three species sequenced here were relatively high, at ranged<br>between 2.08 and 6.57 %. Phylogenetic analysis demonstrates that the studied species of Neoechinorhynchus<br>from grey mullet fish share common ancestor, despite their different geographic location, and are<br>closely related. The terminal position of N. (N.) agilis and N. (H.) personatus on the evolution tree and<br>the low genetic divergence found between them suggests the recent emergence of this group and that the<br>colonization of the North-East Atlantic and the Mediterranean regions could represent a single event. Our<br>phylogenetic analysis, which included several species of the subgenera Neoechinorhynchus and Hebesoma,<br>showed that the latter is a polyphyletic taxon.</p&gt;}, number={1}, journal={Zoodiversity}, author={Sarabeev, Volodimir and Tkach, Ie. and Sueiro, R.
