The new species is named after Sakanari, in honour to her work on the life cycle of trypanorhynch cestodes. 7. Nybelinia schmidti sp. nov. (Figs 14-15) Material examined. Holotype BMNH , G. Ross leg., , 1 adult from the stomach of Isurus glaucus, Algoa Bay, South Africa. DESCRIPTION (Figs 14-15). Measurements: SL=1172; SW=832; pbo=794; pv=473; pb=289; ppb= 46; vel=373; BL=289; BW=104 (94-117); BR=:1; SP=:1. The tentacles are long and slender; TW=; and a basal swelling is absent. The tentacle sheaths are spirally coiled; TSW=46-51. Prebulbar organs and muscular rings around the basal part of the tentacle sheaths are absent. The retractor muscles originate at the basal part of the bulbs. The tentacular armature is homeoacanthous, homeomorphous, and a characteristic basal armature is absent. The massive and rose- thorn shaped hooks increase in size towards the metabasal part of the tentacle, L=; B=l (metabasal) and L=; B= (basal); the hooks in the metabasal part of the tentacle are slightly more slender than in the basal part; hsr=5-6. The strobilar is acraspedote, with about 240 very large segments, wider than long. The proglottids in the anterior part of strobila are 140-155 long x 1400-1540 wide, the final proglottids enlarge in size towards 450-560 x 2800-3080. In mature proglottids, genital.
