Treatment

Murraytrema Price, 1937 View in CoL

Diagnosis: Tegument smooth. Genital pore opening posterior to male copulatory organ (MCO). 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 separated into three zones. Accessory copulatory organ present. Vaginal atrium muscular. Vaginal aperture marginal. Accessory adhesive organ absent. Superficial root of ventral anchor reduced. Parasites of marine perciform fishes ( Sparidae and Sciaenidae ).

Type-species: M. robustum ( Murray, 1931) Price, 1937 from Acanthopagrus australis (Sparidae) . Other species: M. bychowskyi ( Bychowsky & Nagibina, 1977) Oliver, 1987 from Nibea albiflora (Sciaenidae) .

Remarks: Murraytrema is closely related to Lobotrema by sharing the secondary loss of the accessory adhesive organ [45]. However, species of Murraytrema can be differentiated from species of Lobotrema by the presence of a muscular vaginal atrium (sclerotized in Lobotrema ) and three haptoral bars (two in Lobotrema ).
