Rudolphi’s original H. fasciata material. MATERIAL EXAMINED. — Black Sea • 6 adult whole-mounted, 1 sequenced specimens; Severnaya Bay, Crimean Peninsula; intestine of the black scorpionfish, Scorpaena porcus; 44°37’32”N, 33°32’7”E; 27.VII.2000; ISSS RAS 1369.Tr.39.v2-15; GenBank: OK644194 (28SrRNA gene). DESCRIPTION General morphology and digestive system Body elongate-oval, length 1.464 -2.383 (1840), maximum width 620-726 (675) in posterior half of body. Tegument unarmed. Pre-oral lobe absent. Oral sucker spherical or subspherical, 140-189 (167) / 144-184 (167), mouth opening subterminal. Ventral sucker globular or subglobular, 215-285 (237) / 199-250 (224). Oral sucker to ventral sucker width ratio 1: 1.21-1.55 (1.35). Forebody 30.5-36.4 (33.9) % of body length. Prepharynx short, distinct. Pharynx well-developed, 47-83 (67) / 43-88 (59). Intestinal bifurcation in second or posterior third of forebody. Caeca blind distance from caecal ends to posterior end of body reaching 95-171 (137). Male reproductive system Two testes, variously lobed, contiguous, median, tandem, post-equatorial; anterior testis 172-282 (206) / 283-470 (401), posterior testis 188-394 (268) / 359-447 (381). Posttesticular region 13.3-18.2 (14.9) % of body length. Cirrussac well-developed, 319-551 (433) / 65-93 (78), overlapping 2.4-28.7 (22.4)% of ventral sucker. Internal seminal vesicle long, tubular, folded. Pars prostatica tubular, surrounded by numerous prostatic gland-cells. Ejaculatory duct distinct, cirrus not visible. Genital atrium indistinct. Genital pore median, at midlevel of oesophagus. Female reproductive system Ovary variously lobed, median or slightly dextro-sumedian, anterior or slightly antero-dextral to and slightly overlapping anterior testis, 89-136 (118) / 290-393 (340). Canalicular seminal receptacle saccular, antero-dextral to ovary. Laurer’s canal and oötype together with Mehlis’ gland not visible. Uterus preovarian, coiled, intercaecal. Metraterm not visible. Eggs operculate, with long unipolar filament; length without filament 63.0-87.3 (75.1), width 26.1-40.2 (34.2). Vitellarium follicular; follicles in two lateral fields, extending from level anterior quarter or middle of oesophagus to near posterior end of body; fields overlapping caeca dorsally in forebody and uterus area and ventrally in post-testicular region, usually encroaching caeca along rest of their length ventrally and dorsally, not confluent in post-testicular region, usually confluent on dorsal side of forebody; anterior border of ventral follicles some distance posterior to that of dorsal follicles. Excretory system Excretory pore terminal. Excretory vesicle clavate, extending to ovary, posterior end surrounded by numerous glands and small subterminal muscular sphincter. PHYLOGENETIC DATA BI and ML analyses supported the sister position of H. antarcticae to Helicometra sp. described in this study (Fig. 4). The divergence between these species was low (p-distance = 0.7%). The H. antarcticae + Helicometra sp. clade had a sister relationship with the well-supported clade containing Helicometrina nimia Linton, 1910 and other Helicometra spp. Helicometrina nimia was sister taxon to the well-supported terminal Helicometra epinepheli Yamaguti, 1934 + (H. fasciata sensu lato + Helicometra manteri Andres, Ray, Pulis, Curran & Overstreet, 2014) subclade, though this sister relationship was poorly supported in both analyses. Helicometra equilata (Manter, 1933) Siddiqi & Cable, 1960 occupied a basal position to H. nimia and members of the terminal subclade mentioned above.
