Figs 60.13-60.15, 61.12

Distribution.

The species is distributed in southwestern Albania and Corfu, Greece ( Welter-Schultes 2012).

Specimens examined.

Greece, Corfu , Gardiki fortress. 40 m asl, 39°28'37.39"N, 19°53'5.74"E, W. De Mattia and J. Macor leg. and det., 3 dissected spm .

External morphology of the genital organs

(Fig. 60 .13). The V is much longer than the FO. The FDBC is shorter than the SDBC+BC. The BC+SDBC is club-like in shape, with a clear distinction between the SDBC and the BC. The SDBC appears very thin. The D is shorter than the SDBC+BC and slightly thinner. The V is very long, cylindrical and thin in diameter. The PC is ~ 2 × longer than the V. The P is cylindrical spindle-like. The transition between P and EP is only slightly visible and an ER is not clearly detectable. The PR is long and robust. The E is longer than the P but thinner in diameter.

Internal morphology of the genital organs

(Figs 60 .14-60.15). The V is smooth. The P shows transversal, huge smooth pleats that stop before the A. The pseudopapilla is elongated, subquadrangular and smooth. The pseudopapilla originated directly from the epiphallar wall and its base is connected to one EPL. The ER is missing. The epiphallar formula is: PP+ELP. The E shows two smooth ELP. They proximally fade before the VD.
