Pavićević ( CDPV); 13, do., 6.VIII.1990.]

Type locality. Montenegro, Durmitor, Bljušturni Do, meagre alpine meadow mixed with rocks and bushes.

Measurements. Body length male 6.9–7.9, female 5.9–7.3; pronotum length male 1.8–2.1, female 1.9– 2.1; tegmen length male 4.6–5.1, female 1.6–1.9 mm.

Diagnosis. The new species runs out near P. thyrrhenica (Ramme, 1927) using the key of Harz & Kaltenbach (1976). The thyrrhenica group currently comprises three species P. thyrrhenica , P. pavani Failla & Messina, 1979, and P. clavata Failla & Messina, 1980 ( Vidlička & Majzlan 1997) , of which P. clavata is currently regarded a synonym of P. thyrrhenica by Beccaloni (2009). P. montenegrina differs from all three taxa by the shape of the glandular groove and the seventh abdominal tergite of the male being without a pair of lateral bulges but with a single apical bulge, by the simple shape of the male stylus without apical club and without setose apical area, and by the shape of the apical hook of the male phallus.

Description. Male. Tegmina long-ovoid, apex rounded, not completely covering abdomen ( Fig. 20 C). Hind wings strongly reduced, reaching about apex of first abdominal tergite. Glandular pit semicircular without special modifications, reaching behind middle of seventh tergite ( Fig. 20 A); surface covered with rather thin hairs; base largely covered by sixth tergite which is bulging at apex. Tenth tergite with apex rounded. Cerci compressed. Subgenital plate with apical area boat-shaped; apex transversely truncate and provided with one stylus ( Fig. 20 D, E). Phallomeres with hook rather short as in Fig. 20 F–H.

Female. Squamipterous; tegmina with apex transversely truncate and with apico-lateral angle obtusely pointing ( Fig. 20 B). Tenth tergite with apex broadly rounded. Subgenital plate with apical margin broadly rounded in general outline, but somewhat sinuate near base of cerci and in middle of apex.

Coloration. Frons black with a white band on fastigium verticis between compound eyes, lateral ocelli also white and with or without a narrow yellow ring around compound eyes. Pronotum with a semi-ovoid central spot with rounded corners and a white rim ( Fig. 20 B). Meso- and metanota black in male, black with white lateral and apical margins in female ( Fig. 20 B). Abdominal tergites black; in male tergites 2–3 with a narrow and tergites 4–7 with a broad pale band at apical margin; in female all tergites with a narrow white band along apical margin, which is often broadened before lateral margin; lateral margin also white; in female seventh tergite with a pair of white spots reaching from apical rim to base. Tegmina semitransparent, vein white, surface suffused with black spots which are almost absent in costal area and large and more or less fused in anal area. Sternites black with a small white stroke at each side at apico-lateral angles, in female more distinct than in male. Cerci and subgenital plate in male black. In female cerci blackish brown with white tips; subgenital plate black with a white apico-lateral spot at each side. Legs varying from almost completely black with trochanter and genicular area less dark to pale brown with slightly suffused margins; tibial spines always yellowish brown. The extension of the pale and dark colour pattern is variable.

Etymology. Named after its distribution in Montenegro.

Distribution. Presently only known from Durmitor; its occurrence at high altitudes on close mountain ranges in Montenegro and Bosna-Herzegovina is possible.
