Fig. 8. Parachristianella damiani sp. n. from Myliobatis goodei. A - entire worm (holotype MACN-Pa No. 545/1); B - mature proglottid, ventral view (paratype MACN-Pa No. 545/2); C - detail of terminal genitalia, ventral view; D-G - cross sections of mature proglottid; D - at level of testes, anterior to cirrus sac; E - at level of genital atrium. F - posterior to cirrus sac, showing extensive vas deferens. G - at level of ovary, anterior to isthmus. Circummedullary vitelline follicles are not drawn or only partially drawn in figures A-C to allow the view of internal organs. Abbreviations: cs - cirrus sac; ga - genital atrium; isv - internal seminal vesicle; ov - ovary; t - testis; u - uterus; vd - vas deferens; vf - vitelline follicle; vg - vagina; vod - ventral osmoregulatory duct.

A - antibothrial and internal surfaces of tentacle; B - bothrial surface of tentacle; C - external surface of tentacle; D - profiles of hooks on basal and metabasal armature. Abbreviations: br - basal rows; mb - metabasal armature; pr1 - first principal row; pr2 - second principal row; pr6 - sixth principal row.

A - scolex, lateral view; small letters indicate locations of details shown in figures B,C,E-H. B - proximal bothrial surface (acicular filitriches); C - distal bothrial surface (aristate lingulate spinitriches and capilliform filitriches); D - surface of terminal proglottid (acicular to capilliform filitriches); E - apex of scolex (acicular filitriches); F - bothrial margin (capilliform filitriches); G - surface of pars vaginalis (acicular filitriches); H - surface of parts bulbosa (acicular filitriches).
