Charpentieria itala allatollae (Kaeufel, 1928)

Figs 44.7, 44.8, 47.6

Distribution.

This taxon is known to occur in Val Ampola and Val Lorina (Province of Trento, Trentino-Alto Adige, Italy). It is also reported by Gredler (1891) for Monte Tombea as Clausilia tombeana Gredler, 1891 and from other localities in eastern Lombardia by Nardi (2011: 101).

Specimens examined.

Italy, Trentino-Alto Adige, Trento, Storo, Albergo alla Tolla, Val Ampola. 720 m asl, 45°51'7.62"N, 10°38'4.51"E, W. De Mattia and J. Macor leg. and det., 2 dissected spm .

External morphology of the genital organs

(Fig. 44.7). The FO is 1.5 × longer than the V. The FDBC is longer than the BC+SDBC. The BC+SDBC is club-like, with visible distinction between the SDBC and the BC. The apex is rounded. The D is slightly longer than the BC+SDBC, thin and with a round apex. The V is short but wide in diameter. The PC is double as long as the V. The P is swollen along its whole length. The PR is short and robust. The E is longer than the P but thinner in diameter.

Internal morphology of the genital organs

(Fig. 44.8). The A, the V and the P are smooth, with few, very loose and barely visible longitudinal elevations. The PP is almost smooth, elongated with a pointed apex. The PP originates from the distal end of the ELP. The ER is not present. The epiphallar formula is: PP(ELP). The E shows two ELP that proximally fade before the VD.

Remarks.

This taxon, previously considered as a junior synonym of C. itala lorinae (Nordsieck 1963b: 184) was recently elevated (with no explanation) as a valid subspecies by the same author (Nordsieck 2007: 54). It was long considered as a transitional hybrid form between C. clavata and C. itala but this assumption was based exclusively upon shell characters (Nardi 2011: 101). Scheel and Hausdorf (2012: 3799) proved this is not correct as the taxa previously belonging to one or the other species appear deeply intermingled in the phylograms they provided.
