o ~. M K Figure 25 — Wortheniopsis (Sisenna) jancsii n. sp. type specimens to demonstrate the rather low morphological variability of the species. — A-D: holotype, "apertural" view, A = x3, D = xl; lateral view, B = x3, C = xl; E-H: paratype (HGM J.08.5.1.) with best preserved details of the ornament, two lateral views, E- F = x3, G-H = xl; I-J: paratype (HGM J. 08.5.2.) showing earliest preserved whorls, lateral view, I = X3, } = Xl; K-L: paratype (HGM J. 08.5.3.) to display the morphology of the latest (known) whorls, lateral view, K = x3, L = xl; M-P: paratype (HGM J. 08.5.4.) with somewhat more marked ornament, "apertural" and lateral views, M-N = x3, O-P = xl. Sculpture — Network ornament of spiral cords and threads, and collabral threads on whole surface of shell; lunulae also developed on selenizone, but no spiral lines cross them. In last ontogenetic stages, cords became predominant and network vanished in peripheral region and on base. Remarks — Most similar species is Wortheniopsis (Sisenna) hierlat^ensis n. sp. (see above) but it has a simple conical (not coeloconoidal) shell and the character of the ornament does not change in the last growth phases like in Wortheniopsis (Sisenna)jancsii n. sp. EUDES-DESLONGCHAMPS (1849) established the simi­larly shaped Pleurotomaria faveolata var. trochoidea that were named as Pleurotomaria subfaveolata D'ORB. by D'ORBIGNY (1854). FISCHER & WEBER (1997) did not find specimen to design an}' type for this species. They noticed that D'OR­BIGNY's (1854) figure to Pleurotomaria subfaveolata is actually a reproduction of EUDES-DESLONGCHAMPS's (1849) drawing from Pleurotomaria faveolata var. trochoidea. Both figures are different from Wortheniopsis (Sisenna) jancsii n. sp. in having a strong peripheral spiral bulge that is ribbed or nodosed by the drawings, and it remains exposed on all former whorls. No trace of this morphological element has been found on the specimens of Wortheniopsis (Sisenna) jancsii n. sp. Distribution — Úrkút (Bakon}- Mts), Lower(?) Sinemurian. Wortheniopsis (Sisenna) lokutensis n. sp. (Figure 26) 1980: Sisenna turrita (DESLONGCHAMPS, 1849) — SZABÓ, p. 54, pl. 1, 4-5 Holotype — HGM J.08.6.1. (Figure 26: A-B); paratypes: HGM J.08.7.1-2. (both further specimens in Figure 26). Type locality — Lókút (Kericser), Bakony Mts. Type strata — Typical Hierlatz Limestone of stratified development. Name — From the village near the locality. Diagnosis — Turbiniform-conical, thin-walled shell; ramp convex and prominently wide while outer face narrow; base slightly convex and narrowly phaneromphalous; juvenile shell has network ornament of fine threads, but
