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 View Materials . GoogleMaps

Description
SHELL ( Fig. 76 View Figs 76–80 ; Tables 3–4 View Table 3 View Table 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.
Distribution
Landouria schepmani is known only from “Gunung Bungbulan” in West Java (Fig. 54; see Remarks).
