Description
SHELL (Figs 2–3; Tables 3–4). Depressed conical, with 5–5.75 hardly convex whorls; protoconch almost smooth; teleoconch with fine, irregular wrinkles; apical side with indistinct incised spiral lines, umbilical side with more distinct spiral lines; scaly processes sparse, mainly at periphery; tuberculate around umbilicus; brownish-corneous; body whorl keeled; aperture rounded rhombic; upper insertion of peristome descending; peristome expanded, reflexed and slightly thickened; umbilicus slightly eccentric, wide, comprising 29–51% of shell diameter, hardly obscured by columellar edge.
GENITALIA (Figs 15, 29; Table 4). Atrium short; penis long, distal part cylindrical, proximal part globularly dilated; without penis coecum; membranaceous sheath around distal part of penis connected with proximal part of epiphallus by tissue; penial retractor runs from diaphragm to middle part of short cylindrical epiphallus; flagellum moderately long, distal part broader, apically with some indentions, apical part tapering towards its apical end; without node; vas deferens narrow and long; vagina long; oviduct short; peduncle of bursa copulatrix subdivided into a broader, rapidly tapering distal part and a narrower, longer proximal part, ending in an elongate oval bursa beside albumen gland. Right ommatophoral retractor runs between penis and vagina.
Remarks
Landouria winteriana and L. rotatoria are the oldest names for species of Landouria from the Indo-Australian Archipelago. Pfeiffer (1842) described both from Java without more exact locality data. Later, these names have been used for many different species from Java and other islands of the Indo-Australian Archipelago. Thus, it is important to clarify their identity. The original description of H. winteriana was based on material in Pfeiffer’s own collection (Pfeiffer 1852 in 1849–1853). Pfeiffer’s collection was acquired by H. Dohrn and his collection in the Stettin Museum was destroyed during the Second World War (Zilch 1967; Dance 1986). We could not locate type specimens of H. winteriana in other museums (e.g., the collection of von dem Busch in the Geosciences Collection of the University of Bremen, SMF, ZMH). Thus, a neotype has to be designated to clarify the taxonomic status and the type locality of H. winteriana.
We designate a specimen from Gunung Masigit near Padalarang in West Java (ZMA 376193a; Figs 2, 21), which agrees with the original description of Pfeiffer (1842) and the figures of Pfeiffer (1851 in 1849–1853: pl. 95, figs 1–2) in the depressed conical shell with an angular periphery and a wide umbilicus, as the neotype of Helix winteriana Pfeiffer, 1842. This specimen represents a species that is widespread in western Java, which was more intensively studied than other parts of Java in former times (and still today), so it is likely that the neotype actually belongs to the same species as the specimens described by Pfeiffer (1842).
Köhler et al. (in press) recently redescribed L. winteriana under the name L. cf. rotatoria (not Pfeiffer, 1842). The species from Timor named L. cf. winteriana by Köhler et al. (in press) is not closely related to L. winteriana. Although it is more closely related to species of Landouria from Java than to L. timorensis Köhler et al. in press or L. montana Köhler et al. in press from Timor (see Fig. 1; Köhler et al. in press: fig. 2), it is not identical with any of the species described here from Java, but probably represents a new species.
The only available syntype of P. kraepelini (Fig. 3) differs from usual L. winteriana in the smaller shell diameter at three whorls (4.0 mm vs 4.4–5.2 mm in other L. winteriana) and the slightly more pronounced keel. We suppose that P. kraepelini represents a small variety of L. winteriana. However, the specific identity of P. kraepelini and L. winteriana should be checked by an anatomical examination of specimens resembling the syntype of P. kraepelini from Cibodas, its type locality.
Landouria winteriana differs from L. sukoliloensis sp. nov. in the angular body whorl, the not convoluted distal part of the penis, the short epiphallus and the flagellum with a broader distal part with external indentions. This species occurs sympatrically with L. petrukensis sp. nov., from which it differs in the larger size and the angular, less sharply keeled periphery.
Distribution
Anatomically determined samples of L. winteriana are known from Bogor Regency and Padalarang in the mountain region in West Java (Fig. 52). The shells from Tasikmalaya Regency resemble the anatomically determined samples from Bogor Regency and Padalarang. However, their specific identity has to be checked anatomically. In addition, we have anatomically determined a sample from Rakata Island (3 spec. (vouchers for Smith & Djajasasmita 1988), Krakatau Islands, 6°08′46″ S, 105°26′23″ E, MZB 9354).
.
Landouria winteriana has also been recorded from Thailand to the Philippines and the Maluku Islands (Martens 1867; Rensch 1932; van Benthem Jutting 1941, 1950; Vermeulen & Whitten 1998; Boonngam et al. 2008). Besides on Java, L. winteriana might occur on Sumatra, but records from other islands refer to other species.
