Diagnosis.
Protoconch matte; aperture with a rather weak palatal and two weak basal teeth.
Description.
Shell rarely flat, usually spire somewhat elevated; protoconch consists of 1.5-1.75 whorls, very finely granulated, rather matte, not glossy; teleoconch with strong, equidistant ribs that are supported by fine periostracal filaments in fresh shells; rib density variable (43-93 ribs on body whorl), usually widely spaced; between main ribs some fine wrinkles discernible; entire shell with 4.25-4.5 whorls; aperture semilunar or due to the straight basal part triangular; peristome expanded and slightly reflected, especially on the palatal, basal and umbilical areas; palatal tooth of variable strength, usually weak, although present in all adult shells, palatal region of peristome without outer incision; basal portion of peristome usually straight, slightly thickened, with two low denticles that are visible in all adult shells; umbilicus funnel-shaped, wide (although width depends on spire height).
Measurements. SW: 3.6-4.3 mm (median = 4.0 mm), SH: 1.9-2.2 mm (median = 2.0 mm), AW: 1.3-1.7 mm (median = 1.5 mm), AH: 1.3-1.6 mm (median = 1.5 mm), (n = 6; largest and smallest specimens of multiple populations measured).
Differential diagnosis.
See under S. albanicus edentatus ssp. n. Densely ribbed specimens of this subspecies might resemble large specimens of S. unidentatus . The latter species, however, usually has stronger teeth, and narrower aperture.
Variation among specimens.
Some variability was found between populations in terms of rib density, spire height, and strength of apertural teeth.
Distribution.
This subspecies is distributed in northwestern Albania. Most of the known distribution records are from the Kir River Valley. One shell found in the fluvial debris of the Drin River above the Koman Dam extends the range farther eastwards (Figure 4 View Figure 4 ). Welter-Schultes (2012) erroneously reports this taxon from Montenegro.
