The species characters are described on the basis of the type-specimen available in the Neuchâtel University Collection (Host: Myotis bechsteini; locality: Búré d'

Orvai, France; August 1930, leg. H. BALSAC): The strobila is 65 mm in length and 1. 3 mm in maximal width. The proglottids are 23 times wider than long, and broaden slightly posteriorly. The diameters of scolex, the four suckers and rostellum are 180 u, 70-80 u and 80 u, respectively. The crown comprises 30 hooks with prominent guards and a shorter blade. Hook length is 19 u and the hooks base is 20 u (Fig. 6). The pairs of longitudinal excretory ducts are 12, viz. 45 u in diameter. The genital atrium is always unilateral and localizes at the half length of the proglottid. The three testicles, 80-110 a in diameter, are arranged in a transverse row. The cirrus sac measures 85-120 x 35-45 ju, and either attains, or (in older proglottids) intersects the longitudinal excretory ducts. Internal and external seminal vesicle are both present; the former is 30-40 ju, the latter 50 ju in diameter. The ovary is a compact, ovoid or slightly lobular body, 175 x 80 n in size, localizing somewhat aporally in the central field of the proglottid. The vitelline gland, 90 x 45 u in size, is found behind the ovary. The vagina opens into the genital atrium behind the cirrus sac. The seminal receptacle is large, occupying almost half-width of the proglottid; it measures 180-260 x 60-90 u. The uterus is saccular with several compartments, fills the entire medullary space. The eggs measure 45 x 33 u; the oncosphere is 28 x 22 u in size; the embryonal hooks are 15 ju long.
