Turanena (Turanena) andronakii salpinx spec. nov. ( Fig. 7 )

Type locality & type specimens. – Turkey, Vilayet Artvin, 1 km S. Oruçlu, 270 m (41.0994°N 41.8221°E), H.P.M.G. Menkhorst leg., 5.ix.2010. Holotype NMBE 546173 , paratypes NMBE 546174/1, HMK/19, RBA/2, RMNH/2, ZMH/2.

Diagnosis. – A middle-sized, pyramidal-conical shaped Turanena with a dark brown colour, a trumpetlike aperture and a relatively wide umbilicus.

Description. – Shell dextral, pyramidal-conical in outline, with an open, relatively wide, slit-like umbilicus. The 6.6-7.1 whorls are fairly strong convex with a well impressed suture. Teleoconch with irregular, fine, oblique striae; there are no spiral striae. Shell moderately solid, somewhat translucent, glossy, dark brown; there is only a faint, small whitish band behind the peristome. Aperture rounded, trumpet-like, peristome clearly reflected and somewhat thickened. Columellar and palatal insertion connected by a moderately developed but clearly visible callus (which is often thickened near its ends). A subangularis is not present (the thickened parietal callus does not form an angularis, and often extends underneath the palatal insertion of the peristome). The rather indistinct columellar ledge reaches above the middle of the columellar side of the aperture. Palatal peristome at its insertion strongly curved (forming a wide arc), so that the columellar and palatal insertion are juxtaposed.

Measurements (n = 6). – H = 6.7-7.9 (mean 7.3); HLW = 3.8-4.3 (mean 4.1); MH = 2.6-3.0 (mean 2.8); LWD = 3.4-3.6 (mean 3.5); LWM = 3.9-4.4 (mean 4.2); MD = 2.3-2.8 (mean 2.6); NW = 6.6-7.1 (mean 6.9).

Localities. – Known from the locus typicus only (see above).

Derivatio nominis. – The name relates to the somewhat trumpet-like aperture.

Differentiation. – Turanena a. salpinx differs from T. a. andronakii by its smaller size, the more pyramidalconical outline, the more trumpet-like aperture, the wider umbilicus, the more indistinct columellar ledge, and the slightly deeper suture.

Remarks. – Gittenberger & Menkhorst (1993: 81- 83, figs 2, 6-8, pl. 1 figs 5-8) previously described T. a. andronakii under the name T. yusufelensis . They mentioned and figured (:83, pl. 1 figs 7-8) also a small form (“Kleinform”), but apart from the smaller dimensions it hardly differs from the nominotypical form. The “Kleinform” is not identical with T. a. salpinx .

The lectotype of T. a. andronakii has been figured by Schileyko (1984: 313, 315, fig. 223-III) and Sysoev & Schileyko (2009: 57, fig. 23A), who considered andronakii a species of the genus Akramovskiella Schileyko, 1984, as did Schütt (2010: 90). However, there is much uncertainty about the identity of its type species Buliminus (Napaeus) umbrosus Mousson, 1873 , as has been discussed by Bank & Neubert (2016: 63), who also depicted a syntype of umbrosus (: plate 22 fig. 3). The species andronakii seems to fit very well into Turanena , as was originally proposed by Gittenberger & Menkhorst (1993: 81 – under the name yusufelensis ). The genus name Akramovskiella has been misspelled as Akramowskiella by Sysoev & Schileyko (2009) and Schütt (2010).

An isolated locality of T. andronakii inside Turkey (vil. Siirt, Kozluk) has been reported by Şeşen & Schütt (2000: 80, fig. 9). However, the provided picture is too vague to draw any conclusion about the identity of the shell; the identification really needs to be confirmed.
