摘      要：With this work we addressed some molecular systematic issues within the Mugil cephalus species complex.Par­ticular attention was paid to the debated situations of:(i)Mugil liza,occurring in partial sympatry with Mugil cephalus in the northwestern Atlantic,and(ii)Mugil platanus,considered by some authors a synonymy of the former species and distributed in the southwestern Atlantic.We sequenced 79 individuals of a 465-bp portion of the mitochondrial control region(CR)from 8 western Atlantic and 2 Mediterranean localities.In addition,all CR sequences available from GenBank for the studied taxa were added to our dataset,for a total of 323 indi­viduals.Overall,229 haplotypes corresponding to 8 divergent monophyletic lineages were detected.Results of phylogenetic analyses were consistent with the occurrence of past speciation events producing the observed lin­eages.Of these lineages,7 correspond to cryptic species and one is constituted by M.liza and M.platanus.As a matter of fact,these 2 taxa constitute a single lineage within the M.cephalus species complex.However,in­dividuals of M.liza/M.platanus lineage analyzed by means of the 18 mitochondrial markers available in Gen­Bank exhibited a degree of genetic diversity consistent with highly divergent populations.Of the 8 lineages de­tected,the Mediterraean one(type locality)corresponds to M.cephalus;the lineage M.liza/M.platanus should be named M.liza,under the priority principle,and the left 6 lineages need formal description.
