Figs 54 , 76 ; Tables 3–4 Plectotropis schepmani Möllendorff, 1897: 68 (“ Java ”, more exactly ( van Benthem Jutting 1950 ; Zilch 1966 ): “Bungbulan, 1500 feet ”). Landouria winteriana – van Benthem Jutting 1950: 463 (in part). — Zilch 1966: 294 , pl. 7, fig. 7 (in part). (not Pfeiffer, 1842 ) Diagnosis Landouria schepmani is characterized by a depressed conical, sharply keeled shell with distinct incised spiral lines but no discernible scales, and a narrow umbilicus. Material examined Lectotype INDONESIA • lectotype (designated by Zilch 1966 ); West Java , Sukapura , Gunung Bungbulang ; 7°27′ S , 107°36′ E ?; ca 450 m a.s.l. ; SMF 8877 . Paralectotype INDONESIA • 1 spec. ; same data as for lectotype; SMF 8878 . Description SHELL ( Fig. 76 ; Tables 3–4 ). Depressed conical, with 5–5.25 slightly convex whorls; protoconch almost smooth; teleoconch with fine, irregular wrinkles and distinct incised spiral lines; no scales discernible; tuberculate around umbilicus; brownish-corneous; body whorl sharply keeled; aperture rounded rhombic; upper insertion of peristome slightly descending; peristome expanded, reflexed and slightly thickened; umbilicus slightly eccentric, wide, comprising 21% of shell diameter, hardly obscured by columellar edge. GENITALIA. Unknown. Remarks Van Benthem Jutting (1950) and Zilch (1966) synonymized L. schepmani with L. winteriana . However, L. schepmani differs from L. winteriana in having a sharply keeled, more conical shell with distinct incised spiral lines and a narrower umbilicus (U/D 0.21 vs 0.29–0.51 in L. winteriana ). According to the original label, the type locality is Sukapura, Gunung Bungbulan. Van Benthem Jutting (1950: 465) listed a Bungbulan south of Gunung Papandayan ( 7°27′ S , 107°36′ E ). It is not clear whether this is the Bungbulan of Fruhstorfer, because there are also several other localities called Bungbulan in the former Sukapura Regency. For example, there is a Gunung Bungbulang, now called Gunung Bangkuang, in West Java at 7°12′ S , 108°05′ E . Thus, the distribution area of L. schepmani remains dubious. Figs 76–80.
