Body transversely elongate, dorso-ventrally flattened, 500–875 × 1,625 –2,250 (740x1,970); body length to width ratio 1:2.37–1:3.25 (1:2.62); forebody 250–460 (370); hindbody 135–350 (283). Tegument spiny; spines small, extending along entire body length. Eyespots two, 190–290 (226) apart. Oral sucker lacking; ventral sucker near midbody, 78–100 × 83–105 (88 × 103). Pharynx midventral, 75–110 × 88–120 (95 × 109); oesophagus 30–80 (57); caeca form cyclocoel, surrounding gonads. Testes two, symmetrical, deeply lobed; right testis 170–240 × 190–310 (210 × 251); left testis 150–250 × 190–300 (218 × 243); seminal vesicle anterior to right testis, bipartite, posterior part globular, anterior segment tubular, and winding; pars prostatica poorly developed terminating as small ejaculatory duct. Ovary 100–170 × 110–190 (135x156), smooth to slightly irregular, sinistral and anterior to left testis; uterus extending between testes and anterior limbs of caeca, joining ejaculatory duct at genital pore in mid anterior margin of body. Laurer’s canal opening dorsally near left testis; seminal receptacle absent, few sperm seen near proximal part of uterus; vitelline follicles numerous, few in intercaecal region lateral to gonads, but mostly extracaecal and confluent in posterior body; anteriorly follicles restricted to about one third body width on each side. Eggs 80–100 × 30–50 (96 × 44). Excretory vesicle short, tubular; pore terminal. Remarks. This species was first described by MANTER (1970) from Scorpis sp and Microcanthus strigatus ( CUVIER ) ( Kyphosidae ) from Moreton Bay, Australia . CRIBB et al. (1992) reviewed the family Transversotrematidae , redescribing the species in detail, based on material obtained from several species of fish belonging to 7 host families. ABDUL-SALAM and SREELATHA (1992) recovered it from Diplodus sargus ( Sparidae ) from the Kuwaiti coast and described its surface topography and ultrastructure. The distinguishing features of this species, compared with T. haasi WITENBERG , 1944 according to CRIBB et al . (1992) and confirmed in our study, are the restricted distribution of the vitelline follicles anterior to the caeca and the length-width ratio.
