n. sp. (Monogenea: Dactylogyridae) is described based on specimens collected from the gills of the spotted rose snapper (Steindachner) off Mazatlan, Sinaloa, on the northwestern coast of Mexico. The synapomorphy of this genus is the presence of a funnel-shaped base of the male copulatory organ. This new species differs from all other species of the genus by possessing a male copulatory organ with a base with a thickened margin and a membranous accessory piece resembling a scarf and covering about 60% of its distal region. PCR products of the 28S rRNA (831 bp) and 18S rRNA (662 bp) genes were sequenced and submitted to GenBank (accession numbers HQ615997 and JF938069, respectively). BLASTn searches revealed no 100% identical hits with the previously registered monogenean sequences.
