Buliminus (Buliminus) corpulentior E. Gittenberger & Menkhorst, 2006: 101 . New name (nomen novum) for Buliminus (Buliminus) corpulentus E. Gittenberger & Menkhorst, 1991 .

Description. – Shell big to very big, slender ovoid to cylindrical-conic in outline, with an open, slit-like umbilicus. The 6.1-7.0 whorls are moderately convex, and separated by a moderately deep suture. Teleoconch with irregular, fine, oblique striae. At the upper part of the teleoconch and close to the curved peristome there is some very fine granulation; the lower part of the teleoconch shows delicate, irregular, fine spiral striae. Shell solid, not translucent, glossy, bluish-white to light horn-brown; there is a thin whitish band behind the peristome. Aperture more or less ovoid, peristome thickened and strongly re- flected, the columellar and palatal insertion con- nected by rather well developed callus which is more thickened near the columellar peristome as well as the palatal peristome. The thickened callus at the palatal peristome forms a small subangularis that often fuses with the insertion of palatal peristome. The reflected peristome is thin; it mostly curls around itself (i.e. it is curved backwards). The clearly visible columellar ledge reaches halfway to below the middle of the columellar side of the aperture.

Measurements (n = 20). – H 26.6-43.1 mm; LWD 13.3-21.7 mm.

Localities. – Vilayet Mersin: Aydıncık, 3 km towards Gözsüzce (36.1345°N 33.2938°E) ( Gittenberger & Menkhorst, 1991: 79 – sub corpulentus ); Sipanhili, 2 km towards Büyükeçeli (36.1579°N 33.4803°E) ( Gittenberger & Menkhorst, 1991: 79 – sub corpulentus ); Yenikaş (36.1328°N 32.2856°E) (SMNS/4); Sipanhili, 7 km towards Aydıncık (36.1682°N 33.4803°E) (SMNS/1). Vilayet Gaziantep: 17 km E. Sakçagöz (37.17464°N 37.0990°E) ( Gittenberger & Menkhorst, 1991: 83 – sub labrosus ); 20 km E. Sakçagöz (37.1781°N 37.1262°E) ( Gittenberger & Menkhorst, 1991: 83 – sub labrosus ); 1.5 km E. Yeşilce (37.1732°N 37.2233°E) ( Gittenberger & Menkhorst, 1991: 83 – sub labrosus ). Vilayet Hatay: 6 km NE. Samandağı (36.1268°N 36.0364°E) ( Gittenberger & Menkhorst, 1991: 83 – sub labrosus ); Harbiye, 1 km towards Yayladağı (36.1278°N 36.1546°E) (SMNS/6); Tekebaşı, 2 km towards Meydan (36.0399°N 35.9847°E) (SMNS/6).

Differentiation. – Buliminus labrosus differs clearly from B. corpulentior by its dense (but delicate) granulation over its entire teleoconch; spiral striae are missing. B. jordani has the same microsculpture as B. corpulentior , but the whorls are more flattened and the last whorl is more stout. B. zarudnyi lacks spiral striae, lacks granulation and has a less prominent parietal callus.

Remarks. – The shells from the surroundings of Aydıncık are exceptionally large and geographically rather isolated; however, some shells from Harbiye reach essentially the same size as those of Aydıncık. Other populations are markedly smaller than those of Aydıncık, but because there are further no differences in shell morphology or microsculpture, we consider the Turkish populations mentioned as B. labrosus labrosus by Gittenberger & Menkhorst (1991) as belonging to B. corpulentior . The shell depicted by Schütt (2010: 113 fig. a – sub B. labrosus labrosus ), which comes from Harbiye, belongs to B. corpulentior . The same might be the case with the shell figured by Şeşen & Schütt

(2002: 83 fig. 9 – sub B. labrosus ) from Kastabala, but we cannot exclude an identity with B. alepensis without having seen the shell.

Schütt (2010: 111) wrongly mentioned 1991 as the publication date of corpulentior : this is the publication date of the preoccupied name corpulentus .

The closest relative of B. corpulentior , both from a geographical and shell morphological point of view, seems to be B. jordani . This species is common in the northwestern part of Jordan (Neubert, Amr, Waitzbauer & Al Talafha, 2015) and the northernmost part of Israel ( Heller, 2009: 294); it is not known whether B. jordani is also distributed in Lebanon and Syria.
