Fig. 1

Photomicrographs of Bivagina pagrosomi from Sparus aurata in the Red Sea; (a) – whole mount of a paratype adult specimen, dorsal view, AO – anterior attachment organ, H – haptor; (b, c) – anterior end of body, BS – buccal suckers, E – eyes, arrows indicate the position of the two armed vaginae, PH – pharynx, GS – genital suckers; (d) – haptor (H) with clamps (C); (e) – median clamps; (f) – anterior clamps; (i, j) – paired, armed vaginae (V) with crown of spines (VS) within each vagina; (k) – isolated vaginal spine; (l) – egg (EG). Scale bars – a = 500 μm; b = 130 μm; c = 50 μm; d = 100 μm; e = 65 μm; f, i = 20 μm; j = 4 μm; k =50 μm
