Description

SHELL ( Fig. 75 View Figs 72–75 ; Tables 3–4 View Table 3 View Table 4 ). Depressed conical, with 5–6.25 slightly convex whorls; protoconch almost smooth; teleoconch with irregular wrinkles; apical side with indistinct incised spiral lines, umbilical side with more distinct spiral lines; scaly processes not observed; tuberculate around umbilicus; brownishcorneous; body whorl keeled; aperture oval; upper insertion of peristome hardly or distinctly descending; peristome expanded, reflexed and slightly thickened; umbilicus very wide, comprising 37–38% of shell diameter, hardly obscured by columellar edge.

GENITALIA. Unknown.

Remarks

Martens (1867) recorded L. moussoniana from Wonosari in the Tengger Mountains together with L. smimensis and another form of Landouria that he included in his L. intumescens . Landouria moussoniana differs from L. intumescens in having a more tightly coiled, less sharply keeled shell with a wider umbilicus (U/D 0.37–0.38 vs 0.22–0.34 in L. intumescens ).

Distribution

Landouria moussoniana is endemic to the Tengger Mountains in East Java (Fig. 55).
