Diagnosis

Landouria parahyangensis sp. nov. is characterized by a sharply keeled, tightly coiled conical shell with a very wide umbilicus.

Etymology

Landouria parahyangensis sp. nov. is named after its occurrence in the mountainous region Parahyangan. In the Sundanese language, the name ʻParahyanganʼ means ʻthe abode of hyangs (gods)ʼ, which were supposed to reside in the mountain tops.

Description

SHELL (Fig. 48; Tables 3–4 View Table 3 View Table 4 ). Conical, with 6.5–7 hardly convex whorls; protoconch almost smooth; teleoconch with fine, irregular wrinkles; without distinct incised spiral lines; scaly processes sparse, only at periphery; 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 hardly eccentric, wide, comprising 39–45% of shell diameter, hardly obscured by columellar edge.

GENITALIA. Unknown.

Remarks

Landouria parahyangensis sp. nov. resembles L. epiplatia (Figs 26–28) with regard to the wide umbilicus. It differs from L. epiplatia in the less sharply keeled, higher, conical shell (H 8.4–9.3 mm vs 5.7–6.9 mm in L. epiplatia ; D/H 1.69–1.94 vs 2.03–2.94 in L. epiplatia ) with more whorls (6.5–7 vs 5.25–6.25 in L. epiplatia ). Landouria parahyangensis sp. nov. also resembles L. naggsi sp. nov. (Fig. 25). For differences, see remarks under that species.

Distribution

Landouria parahyangensis sp. nov. is endemic to the Karangnunggal karst area in West Java (Fig. 54).
