Distribution.

The nominate subspecies is distributed from southern Dalmatia (from the Neretva River southward), Herzegovina, Montenegro to northern Albania.

External morphology of the genital organs (Figs 59 .1, 59.3, 59.5).

The V is much shorter than the FO. The FDBC is longer than the SDBC+BC. The BC+SDBC is club-like in shape, with a more or less clear distinction between the SDBC and the BC. The D is extremely longer than the SDBC+BC but remarkably thinner. The V is very short but wide in diameter. The PC is ~ 4-5 × longer than the V. The P is cylindrical or slightly swollen. The transition between P and EP is clearly visible. The PR is short but very robust. The E is usually as long as the P and thinner in diameter.

Internal morphology of the genital organs

(Figs 59 .2, 59.4, 59.6). The V is smooth. The P shows a pattern of irregularly fringed or smooth pleats, sometimes forming and irregular net-like pattern, usually disappearing toward the A that is smooth. The pseudopapilla small and roundish. It originates from the E wall, which is connected with the ELP. The epiphallar formula is ER(PP+ELP). The E shows two fringed ELP, sometimes remarkably irregular and connected with small fleshy transversal bridges. They proximally fade before the VD.
