Oliveriplectanum Domingues & Boeger, 2008, n. gen.

Description

Oliveriplectanum n. gen.

Synonymy: Diplectanum Diesing, 1858, partim

Diagnosis: Tegument smooth. Genital pore opening anterior to male copulatory organ (MCO) [59]. Genital atrium muscular. Vas deferens intercaecal or looping left intestinal caecum. MCO tubular, composed of 2 nested tubes; external tube uniform. Accessory piece absent. Prostatic reservoir simple. Accessory copulatory organ absent. Vaginal atrium muscular. Vaginal aperture marginal. Squamodiscs present, ventral, dorsal; anterior rows of rodlets with closed rings [58]. Superficial root of ventral anchor developed [57]. Parasites of marine perciform fishes (Lutjanidae, Priacanthidae).

Type species: Oliveriplectanum priacanthi (Yamaguti, 1968) n. comb from Heteropriacanthus cruentatus (Lacépède) (Priacanthidae).

Other species: O. opakapaka (Yamaguti, 1968) n. comb. from Pristipomoides filamentosus (Valenciennes) (Lutjanidae), and Aphareus rutilans Cuvier (Lutjanidae); O. curvivagina (Yamaguti, 1968) n. comb from Pristipomoides sieboldii (Bleeker), and Pristipomoides auricilla (Jordan, Evermann & Tanaka).

Remarks: Oliver (1987) transferred D. priacanthi, D. curvivagina, and D. opakapaka to Cycloplectanum and included them into a morphologic group based on the presence of an arched male copulatory organ. However, several authors did not accept Cycloplectanum as a valid taxon and considered that species belonging to this genus should represent species of Diplectanum and Pseudorhabdosynochus (Kritsky & Beverley-Burton 1986; Justine & Euzet 2006). Presence of a genital pore opening anterior to male copulatory organ and squamodiscs with anterior rows of rodlets with closed rings distinguish Oliveriplectanum n. gen. from these later genera. The genus is named after Dr Guy Oliver, in recognition of his valuable work on the Diplectanidae.
