Distribution.

The nominate subspecies is restricted to the Island of Corfu, Greece.

Specimens examined.

Greece, Corfu , Lafki. 420 m asl, 39°46'18.23"N, 19°50'47.23"E, [Lab ID St 9_2, COI: MW758964 , ITS2: MW757041, MW757042, MW757043 ], W. De Mattia and J. Macor leg. and det., 2 dissected spm .

External morphology of the genital organs

(Fig. 63 .1). The V is much shorter than the FO. The FDBC is longer than the SDBC+BC. The BC+SDBC is spindle-like in shape, with a clear distinction between the SDBC and the BC. The D is much longer than the SDBC+BC and much thinner. The V is short but wide in diameter. The PC is ~ 2.5 × longer than the V. The P is cylindrical and slightly swollen. The transition between P and EP is not clearly visible and ER is difficult to detect. The PR is short and robust. The E is longer than the P but thinner in diameter.

Internal morphology of the genital organs

(Fig. 63 .2). The V presents many smooth longitudinal pleats that stop before entering the A. The A and the P are smooth. The pseudopapilla is smooth, long and occupies almost the whole penial volume. It originates directly from the wall of the E and it is not connected with the ELP. The E shows two moderately fringed ELP. They proximally fade before the VD. The epiphallar formula is PP+ELP.
