Endoplocus staszycii

Overview & Synopsis

Endoplocus staszycii (Zeuschner, 1849)?Plate 13: figs 1, 2? 1850 – Actaeon staszycii n. sp. – Zeuschner: 130, pl. 17, figs 16–19.1855 – Nerinea staszycii Zeuschner – Peters: 350, Tas. 2, figs 6–9.1870 – Nerinea staszycii Zeuschner – Gemmellaro: 16, pl. 3, figs 8–10.1998 – Endoplocus staszycii (Zeuschner, 1849) – Wieczorek: 319, pl. 2, figs 4–6 (here more chresonymy and synonymy).Material.4 specimens, SNSB-BSPG 2016 XXI 1905 –1908.Description.Shell stout with egg-shaped outline, consisting of few whorls; largest specimen 27 mm high; body whorl higher than the spire; whorl face weakly convex; whorls relatively high, smooth; sutures marked by a narrow ramp; transition from whorl face to base evenly rounded; base strongly convex, smooth; aperture not preserved; 2 (3?) columellar and palatal plaites as well as a parietal plait visible in longitudinal section.Remarks.According to Peters (1855), Nerinea staszycii Zeuschner, 1850 is a very variable species. The specimens illustrated by Peters (1855, pl. 2: figs 6–9) correspond to the present material assigned to this species. Actaeon staszycii Zeuschner, 1850 is more slender, the spire is higher and it has more whorls. Itieria austriaca Zittel, 1873 has a subsutural row of nodes. Nerinea staszycii Zeuschner sensu Gemmellaro (1870) has a lower last whorl in relation to the spire height and the shell is more slender. Phaneroptyxis simmenensis Ooster sensu Cossmann (1898) is more slender and its body whorl is more cylindrical.
