Diagnosis

Landouria smimensis is characterized by a small, depressed conical shell with hairs and a usually slightly angular body whorl, a long penis, which gradually tapers towards its proximal end, and a slightly crenated, gradually tapering flagellum.

Description

SHELL ( Figs 11 View Figs 6–11 , 78–80 View Figs 76–80 ; Tables 3–4 View Table 3 View Table 4 ). Depressed conical, with 4.5–5.5 convex whorls; protoconch almost smooth; teleoconch irregularly striated, with indistinct incised spiral lines; with hair-like processes; not tuberculate around umbilicus; brownish-corneous; body whorl slightly angular or rounded; aperture oval; upper insertion of peristome hardly descending; peristome sharp; umbilicus slightly eccentric, narrow, comprising 18–32% of shell diameter, hardly obscured by columellar edge.

GENITALIA ( Figs 43 View Figs 29–47 , 67 View Figs 63–71 ; Table 4 View Table 4 ). Atrium short; penis long, gradually tapering towards its proximal end; without penis coecum; surrounded by a membranaceous sheath connected to proximal epiphallus by tissue; penial retractor runs from diaphragm to middle part of cylindrical epiphallus; flagellum moderately long, narrow, broadest in its middle part, without node, gradually tapering towards its proximal end, slightly crenated; vas deferens narrow and long; vagina broad and short; oviduct short, proximally slightly tapering; peduncle of bursa copulatrix subdivided into a broad abruptly tapering distal part and a narrower and longer proximal part, ending in an elongate oval bursa beside albumen gland. Right ommatophoral retractor runs between penis and vagina.

Remarks

The original spelling of the species name was Helix smimensis Mousson, 1848 . This was not an inadvertent error, such as a lapsus calami or printer’s error, because this spelling was also used later by Mousson (1849). Thus, H. smimensis is the correct original spelling according to ICZN, Article 32. The name was intentionally changed to H. smironensis by Mousson (1850) and to H. smiruensis by Martens (1867). Both names are unjustified emendations, which are available with these authors and dates, and which are junior objective synonyms of H. smimensis (ICZN, Art. 33). According to ICZN, Article 33.2.3.1, an unjustified emendation may be deemed to be a justified emendation, if it is in prevailing usage. Helix smiruensis was used by Tryon (1887), Leschke (1914) and Rensch (1932), L. smironensis by van Benthem Jutting (1950) and Vermeulen & Whitten (1998), the incorrect subsequent spelling Landouria cf. smiroensis by Boonngam et al. (2008) and the correct original spelling L. smimensis by Köhler et al. (in press). Thus, there is no prevailing usage of any of the emendations and the correct original spelling should be used.

The voucher specimen for L. tenggerica of Rensch (1934) from Gunung Lawu, 2400 m a.s.l. (ZMB 76086) is tuberculate around the umbilicus and is a juvenile of a different species.

Distribution

Landouria smimensis View in CoL is known from the Tengger Mountains in East Java (Fig. 52). It has also been recorded from other mountains in Central and East Java ( Rensch 1934), Lombok ( Rensch 1932), Bali ( Vermeulen & Whitten 1998) and Thailand ( Boonngam et al. 2008), but these populations probably represent separate species.
