Etymology

Named after my friend and renowned malacologist Peter Glöer from Hetlingen, Germany, who largely contributed to the freshwater gastropod fauna of the Balkans.

Description

Inflated conical 3.38 mm-high shell with dominant convex body whorl. Light yellowish corneous shell with smooth shiny surface, weak close-set axial ribs and 4.5 convex whorls separated by a weak suture. Protoconch surface smooth, weakly and distantly pitted with larger weak malleation over the pitting. Apex blunt and flat. Umbilicus closed. Elongate asymmetric-oval aperture attached to the body whorl by a weak sulcus. Peristome callous and blunt, not reflexed. Outer lip almost flat at and weakly sinuated at columellar profile. Aperture profile aligned with the body whorl and with the evenly tapering whorls at basal view.

Differentiating features

The shells of T. gloeri sp. nov. differ from T. ovalis ( Fig. 7 View Fig I–K) from spring of Bunica River near Hodbina (but not found in Vrelo “Buna” as declared by Kuščer (1933) as its type locality) by its more slender shell shape, closed umbilicus and more flat protoconch. From the type species T. vruljakensis it differs by adapically more protruded and differently shaped aperture, by more coarsely ribbed teleoconch surface and by more smooth protoconch surface. Shell morphometry comparison with the related Travunijana species is presented in the Table 4.
