adult whorls ornamented by dense, fine spiral threads crossed by growth-lines only; dense, somewhat stronger threads cover full base. Material — Most of the available 28 specimens are strongly damaged owing to their extremely thin—walled shell. Measurements 11 HL HP D W AA AL holotype *23 •15.5 *10.5 *18 *11.5 61° 61° paratype HGMJ.08.7.1. **23 **i g *28 *50° paratype HGM J. 08.7.2. **35 **23 **37 Figure 26 — Wortheniopsis (Sisenna) lokutensis n. sp. — A-B: holotype in dorsal view, A = xl, B = x3; C-D: paratype (HGM J.08.7.1.) to show shape and ornament of the adult whorls, C = xl, D = X3; E: inflated last whorl of the largest available specimen (paratvpe HGMJ.08.7.2.), xl. Shape — Turbiniform-conical, thin-walled shell with blunt apex. Nucleus and first protoconch whorl slightly depressed; next three whorls probably belonging to orthostrophic protoconch. With appearance of nearly midwhorl angulation, pentagonal axial whorl-section of whorls develops at end of fourth volution. Selenizone runs at middle of early whorls, on lower rim of somewhat convex ramp that gradually widened relative to outer face, therefore selenizone shifted below midwhorl on postjuvenile whorls. It forms concave belt, bordered by two spiral cords. Immediately below selenizone, narrow, slighdy concave outer face developed with angular periphery abapically alongside. Base slighdy convex and narrowly phaneromphalous. Sculpture — Ornament of protoconch, disregarding first half whorl, and juvenile shell (about five whorls) cancellate and granulate at crossing points of network. Adult shell ornamented with fine growth-lines, and more regularly spaced, dense, fine spiral threads of similar strength. From these latter, only those two, bordering selenizone, and 3 to 4 ones, situating on periphery became cords. Stronger, densely developed, almost uniform spiral threads cover narrowly phaneromphalous base. Remarks — The width of the outer face, compared to the distance between upper and lower sutures and/or to the width of the ramp, smallest of all published Wortheniopsis (Sisenna) species. Concomitant character is the broadest ramp; this shape makes Wortheniopsis (Sisenna) lokutensis n. sp. distinguishable from the related species. From the "morphes" of FISCHER & WEBER (1997) Sisenna faveolata subdivision, ellipsoidea and pinguis are comparable to Wortheniopsis (Sisenna) lokutensis n. sp. because of their subglobular adult whorl. However, the outer face/ramp ratio as distinctive character is working in these cases, too. Besides, their spiral angle is considerably larger and they seem to have smaller number of whorls at same dimension; "morphe" ellipsoidea has flat selenizone without delimiting spiral cords, and "morphe" pinguis has granulate ornament, respectively. Distribution — Herend, Kisnyerges-árok: Jamesoni to Ibex Zones; Lókút, Kericser: beds with mixed Obtusum to Ibex Zone fauna and Davoei Zone; Szentgál, Gombáspuszta: Ibex Zone; Eplény, Kávás-hegy: Davoei Zone (all in the Bakony Mts).
