title: Helicometra boseli Nagaty, 1956 (Digenea: Opecoelidae) in Sargocentron spiniferum (Forsskål) (Beryciformes: Holocentridae) from New Caledonian waters with a review of the Helicometra spp. in holocentrids.
abstract: The species Helicometra boseli Nagaty, 1956 is redescribed from the holocentrid Sargocentron spiniferum (Forsskål) off New Caledonia. It is characterised by a short forebody, long cirrus-sac, reaching well into the hindbody, and undulating lateral margins. Stenopera rectisaccus Fischthal & Kuntz, 1964 is considered a synonym. The status of the four species of Helicometra Odhner, 1902 from holocentrids is discussed. Three of the Helicometra species reported from holocentrids exhibit characteristics used to erect the genus Stenopera Manter, 1933, which is currently considered a junior synonym of Helicometra.
