| Description | The yellowfin goatfish Mulloidichthys vanicolensis (Valenciennes, 1831) is found widely in tropical marine waters of the Indo-Pacific. Although it is valued as food fish in many countries, there are no reports on parasites from the species. Recently, we collected numerous dactylogyrids from the gills of three fresh specimens of M. vanicolensis purchased at the fish market in Nouméa, New Caledonia. Examination of these monogeneans revealed the presence of five new species for which two new genera were proposed: Volsellituba n. gen. and Pennulituba n. gen. Volsellituba and Pennulituba resemble dactylogyrid genera whose species lack eye spots and possess tandem or slightly overlapping gonads, single prostatic reservoir, a copulatory organ without an accessory piece, a dextroventral non-sclerotised vagina, ventral and dorsal anchor/bar complexes, and hooks with shanks comprising one slender unit. Volsellituba is characterised by species having ventral tegumental folds or an auxiliary vaginal structure at level of the vagina, a copulatory organ with subterminal base opening, and a two-pieced dorsal bar. The following new species of Volsellituba are described: V. orchidea n. sp. (type), V. nabla n. sp., and V. elephantina n. sp. Pennulituba is distinguished by species possessing a copulatory organ with wing-shaped membrane and a dorsal bar with poorly to non-sclerotised medial part. The genus includes Pennulituba piratifalx n. sp. (type) and P. cymansis n. sp. |
