Type locality ITALY • Lucchio, Lucca. Description SHELL . As in C . ( T .) agriotes . MEASUREMENTS . 26 ♀♀ : whorls =7.2–8.8, H = 7.6–9.5 mm , H/W=2.65–3.08, roundness =0.1–0.17, ribs incl.= 54–60°, apert. incl.= 15–24°, ribs/mm 1 st wh.= 3–9, ribs/mm 4 th wh.=4–11, umb. =hidden. FEMALE GENITAL ORGANS . As in C. ( T .) affine . Remarks The relative position in the phylogenetic trees with respect to the very similar agriotes suggests to consider it a separate species. The samples classified with this species without molecular data are identified according to distributional data. The topotypical population of the species lives in the Garfagnana area, which borders to the west with the Apuane Alps and is isolated from the other conspecific populations. Other isolated populations live in “limestone islands” in the Tuscany region (Roccalbegna, Monte Calvi). Fig. 102.
