Landouria conoidea (Leschke, 1914) comb. nov. Figs 4, 6, 53; Tables 3–4 Plectotropis conoidea Leschke, 1914: 212, figs 8–9 (“Buitenzorg”). Landouria rotatoria – van Benthem Jutting 1950: 461 (in part). (not Pfeiffer, 1842) Diagnosis Landouria conoidea is characterized by a small, conical, sharply keeled shell with tubercles all over the shell surface. Material examined Syntypes INDONESIA • 8 spec.; West Java, Bogor; 6°36′ S, 106°48′ E; ZMH 98144. Other material INDONESIA • 10 spec.; West Java, Bogor; 6°36′ S, 106°48′ E; ZMH 98145. Description SHELL (Figs 4, 6; Tables 3–4). Conical, with 4.75–5 slightly convex whorls; protoconch almost smooth; teleoconch with fine, irregular wrinkles; apical side without distinct incised spiral lines, umbilical side with indistinct spiral lines; with tubercles all over shell surface that carry scaly processes or hairs mainly at periphery; tuberculate around umbilicus; brownish-corneous; body whorl sharply keeled at beginning; aperture almost circular; upper insertion of peristome slightly descending; peristome expanded, reflexed and slightly thickened; umbilicus hardly eccentric, wide, comprising 30–43% of shell diameter, hardly obscured by columellar edge. GENITALIA. Unknown. Remarks Landouria conoidea differs from L. winteriana, which occurs in the same region in West Java, in the smaller shell diameter (7.6–8.7 mm vs 9.7–12.6 mm in L. winteriana), the higher shell form (D/H 1.48–1.54 vs 1.55–2.07 in L. winteriana), the more pronounced keel and the presence of tubercles all over the shell surface (Fig. 6). With regard to the conical shell form, L. conoidea resembles L. naggsi sp. nov. (Fig. 25), from which it differs in the less elevated (D/H 1.48–1.54 vs 1.21–1.37 in L. naggsi sp. nov.), smaller shell (D 7.6– 8.7 mm vs 11.6–14.0 mm in L. naggsi sp. nov.) with fewer whorls (4.75–5 vs 6.25–7 in L. naggsi sp. nov.), the more pronounced keel and the shell sculpture consisting of tubercles vs longish scales in L. naggsi sp. nov. Distribution Landouria conoidea is so far known only from Bogor in West Java (Fig. 53).
