Parasitic copepods from Egyptian Red Sea fishes: Bomolochidae Claus, 1875.

Two species of parasitic copepods from the genus Bomolochus von Nordmann, 1832 (Cyclopoida: Bomolochidae) are redescribed in detail, based on material collected from the gills of Red Sea fishes. Host material was caught at El-tor, near Sharm El-Sheikh, and in the Gulf of Suez, Egypt. Both sexes of Bomolochus bellones Burmeister, 1835 were collected from the gills of a needlefish Tylosurus choram (Rüppell) caught in the Gulf of Suez. This is a new host record. The female is well characterised so only the male is described. Adult females of Bomolochus minus Lin & Ho, 2005 were obtained from the branchial cavities and gills of mojarra Gerres oyena (Forsskål). This species was known only from its original description in Taiwan, and this report constitutes a new host record and a significant range extension. Both parasite species are new records for Egyptian Red Sea waters.
