Rupestrella kabyliana ( Letourneux, 1870)

Type locality: Algeria, rocks of Tablabalt near Fort Napoleon (36.637°N / 4.201°E) .

Notes.—Two samples of ‘ Pupa penchinatiana ’ from Algeria in the Colln Bourguignat (BG12985, 12986), most probably belong to R. kabyliana . The shells have (1) more prominent and regular riblets, expecially on the spire, (2) the apertural teeth are more prominent, (3) the apertural lip is somewhat reflexed, without being conspicuously thickened, and (4) the apical whorls are in general slightly more slender. The differences are slight indeed, which makes once more clear that the genera Chondrina and Rupestrella cannot be distinguished unequivocally on the basis of only shell characters.
