Figs 43.1, 43.2, 47.1

Distribution and remarks.

Charpentieria ornata has a wide distribution that includes Sudetes, southeastern Alps (Slovenia) and the western Dinarids ( Welter-Schultes 2012). This species has a detached distribution which is not overlapping with C. itala and it is also frequently found (as the latter species) in disturbed habitats (walls, artificial limestone cliffs etc), revealing a good degree of anthropophily. Charpentieria ornata presents, for the subgenus, an unusually short pseudopapilla. Moreover, contrary to C. itala , the peristome is never detached from the body whorl.

Specimens examined.

Croatia, Ogulin city centre, 320 m asl, 45°16'2.55"N, 15°13'33.34"E, W. De Mattia and J. Macor leg. and det. 3 dissected spm .

External morphology of the genital organs

(Fig. 43 .1). The FO is almost as long as the V. The FDBC is as long as the BC+SDBC. The BC+SDBC is club-like to cylindric in shape, with slight distinction between the SDBC and the BC. The apex is wide and rounded. The D is slightly longer than the BC+SDBC with a round apex. The V is long and slim. The PC is only 1.5 × longer than the V. The P is swollen. The PR is short and robust. The P-E transition is clearly visible. The E is as long as the P and much thinner in diameter.

Internal morphology of the genital organs

(Fig. 43 .2). The V is smooth. The P presents big irregular longitudinal pleats that reach the A. The pleats are smooth and discontinuous, irregularly splitting and merging one into another. The PP is smooth and short, almost triangular and doesn’t reach the A. It is detached from the ELP. The epiphallar formula is: PP+ELP. The ELP are small and smooth. They proximally fade before the VD.
