Original description. M’Intosh (1885): 368, Plate XXXVIa, fig. 4. Host. Ilyphagus wyvillei (M’Intosh, 1885) [as Trophonia wyvillei ] (family Flabelligeridae). Type locality. Embedded in specimen of I. wyvillei trawled at H.M.S. Challenger station 157 (Antarctic Ocean); 53º55’ S, 108º 35’ E; depth 1,950 fathoms (3,566 m); diatom ooze. Material examined. Holotype ♀ in alcohol (NHMUK reg. no. 1939.4.24.1); attached to the bases of the gills; collected 03 March 1874. Inspection of the dissected holotype of I. wyvillei (NHMUK reg. no. 85.12.1.261) failed to reveal the second specimen mentioned by M’Intosh (1885). Redescription of female. Body highly transformed and lacking any external trace of segmentation or appendages; consisting of two parts, endosoma and ectosoma, possibly connected by short frontal stalk; stalk and endosoma presumably torn off during dissection. Ectosoma (Fig. 12 B) almost spherical, about 520 µm in diameter; frontal surface with numerous minute pores around connection with endosoma (Fig. 12 D, E). Genital apertures paired, located ventrolaterally almost on opposite side of stalk (Fig. 12 B–D) and carried on highly sclerotized genital swellings; closed off by strongly developed semicircular opercula, derived from sixth legs; opercula with large membranous insert at base; opening and closing by strong muscles inserting on opercula and posterior wall of genital antra, respectively (Fig. 12 B–D). Small median copulatory pore located in shelf-like depression between genital apertures (Fig. 12 B, C), leading via short copulatory duct to seminal receptacle(s); small spiniform papillae discernible, positioned posteriorly to ...
