Travunijana edlaueri (Schütt, 1961) comb. nov. Figs 13D, 16 C–D Plagigeyeria edlaueri Schütt, 1961:132–133, fig. 1. Plagigeyeria edlaueri – Schütt 1972: 115, 119, pl. 6 fig. 7. — Willmann & Pieper 1978: 126. — Bole & Velkovrh 1986: 202. — Bodon, Manganelli & Giusti 1996: 33, fig. 13. — Bank 2013: Fauna Europaea v. 2.6. — Bank & Neubert 2017: 24. Diagnosis Shell large for the genus (3.7 mm), conical spire with regularly tapering whorls, weak suture and rather sharp apex, body whorl triangular, centrally bumped, shell surface smooth shiny, aperture wide, callous, but not expanded and conspicuously protruding at the labral view. Lateral labral profile is straight and columellar labrum possesses a weak negative sinuation at the slightly protruding columellar fold. Protoconch surface overall covered by regular, large and very deep pitting. Distribution Empty eroded shells of T. edlaueri appear in the sediment of springs at the side of the Hutovo (Svitavsko) Blato depression (2 m a.s.l.) (Vrelo “Sopot Mlin” and at Sjekoše) and in Vrelo “Glušči” (4 m a.s.l.) near Metković in Croatia. The springs are draining karst water from main swallow holes of the River Trebišnjica at the end of Popovo Polje (227 m a.s.l.) and from Gradac Polje (88 m a.s.l.), and are connected to the alluvial delta of the Neretva River. Remark s Travunijana edlaueri is one of the largest representatives of the genus, frequently reaching over 3 mm (max. 3.7 mm). Its general shell shape is most similar to Plagigeyeria of all the species of Travunijana, however the pitted protoconch structure and straight labral / weakly sinuated columellar labrum indicates its position within the genus Travunijana or maybe within a new unrecognized genus.
