Pseudodiplectanum Tripathi, 1957

Diagnosis: Tegument smooth or scaled. Genital pore opening posterior to male copulatory organ (MCO). Genital atrium muscular. Vas deferens intercaecal. MCO tubular, composed of nested tubes [31], twisted or sinuous; external tube uniform; accessory piece present (exceptionally absent on P. c a b a l l e ro i). Prostatic reservoir simple. Accessory copulatory organ absent. Vaginal atrium sclerotized. Vaginal aperture medial. Squamodiscs ventral, dorsal; anterior rows of rodlets with open rings. Ventral anchor probe shape [32]. Parasites of marine teleosteans fishes ( Pleuronectiformes and Osteoglossiformes ).

Type-species: P. cynoglossum Tripathi, 1957 from Cynoglossus arel (Bloch & Schneider) (type host), and Cynoglossus bilineatus (Lacépède) (Cynoglossidae) .

Other species: P. bychowskii Nagibina, 1977 from C ynoglossus bilineatus ; P. caballeroi Nagibina, 1977 from Symphurus orientalis (Bleeker) (Cynoglossidae) ; P. gibsoni (Oliver, 1980) Oliver, 1987 from Microchirus variegatus (Donovan) (Soleidae) ; P. kearnei Vala, Lopez-Roman & Boudaoud, 1980 from Solea solea (Linnaeus) ; P. lucknowensis Agrawal & Sharma, 1986 from Chitala chitala (Hamilton) ( Notopteridae , Osteoglossiformes ); P. syrticum Derbel, Boudaya & Neifar, 2007 from Synapturichthys kleinii (Risso) (Soleidae) .

Remarks: Oliver (1987) recognized two different morphological types of MCO in Pseudodiplectanum : (1) spiraled ( P. bychowskii , P. caballeroi , P. cynoglossum ) and (2) tubular with accessory piece ( P. gibsoni , P. kearni ). Except for P. caballeroi , all the other species present accessory piece. However, despite the fact that we could not confirm the presence of accessory piece in the unavailable specimens of P. caballeroi , we decided to retain all species in the genus, without proposal of new taxonomic rearrangement until information about this species be available.
