Figs 60.3, 60.4, 61.5, 61.6

Distribution.

This species is restricted to the eastern side of the Monti Alburni, Campania, Italy.

Specimens examined.

Italy, Campania, Salerno, San Rufo, Passo della Sentinella. 850 m asl, 40°25'27.06"N, 15°26'17.44"E. W. De Mattia and J. Macor leg. and det., 3 dissected spm .

External morphology of the genital organs

(Fig. 60 .3). The FO is 4-5 ×longer than the V. The FDBC is 2 × as long as the SDBC+BC. The BC+SDBC is slightly club-like in shape, with a more or less clear distinction between the SDBC and the BC. The D is longer than the SDBC+BC. The V is short. The PC is ~ 3 × longer than the V. The P is irregular and folded in shape. The transition between P and E is slightly visible. The PR is very long and slim. The E is half as long as the P and thinner in diameter.

Internal morphology of the genital organs

(Fig. 60 .4). The V is smooth. The P shows five to six irregular transverse smooth pleats that stop before entering in the atrium. The pseudopapilla is moderately short with a smooth surface. It originates from the E wall. The epiphallar formula is PP+ELP. The E shows two smooth ELP. They proximally fade before the VD.

Remarks.

Stigmatica ernae shows an extremely long FO and, as a whole, the female part of the distal genital organs shows an ectomorphic type (except as regards the vagina) whereas the PC is relatively short.
