Measurements. see Tabs. 5–6 View TABLE 5 View TABLE 6 .

Diagnosis. The new subspecies is similar to the nominate subspecies P. a. affinis . It maily differs by the male stridulatory file and stridulation as outlined in the key and discussed above.

Description. A medium-sized to smaller, slender subspecies. Fastigium verticis ( Fig. 7 View FIGURE 7. A – H T) narrower than scapus ( Tab. 5 View TABLE 5 ), dorsally furrowed. Postfemora with 3–12 spinules on interior and exterior ventral margins.

Male. Pronotum ( Figs. 7 View FIGURE 7. A – H R–S) distinctly raised in metazona; lateral margins diverging in metazona; apex concave to almost triangularly excised. Abbreviated tegmina covered by pronotum in basal third to basal half. Stridulatory file ( Fig. 9 View FIGURE 9 C) with 130–164 teeth ( Tab. 6 View TABLE 6 ). Cerci ( Fig. 7 View FIGURE 7. A – H U) strongly curved before apex; gradually narrowing into apical tooth. Subgenital plate narrowing behind middle, a short apical part narrow with almost subparallel lateral margins; with or without a weak median keel in apical half; apex with small round projections at both corners, subtruncate in between, but often very faintly excised in middle (in two males bred from the egg distinctly excised).

Female. Pronotum with dorsal margin substraight to slightly raised in metazona; apex slightly concave. Tegmina overlapping, almost completely hidden under pronotum; apex truncate. Cerci faintly curved, apex subobtuse. Subgenital plate triangularly rounded with indication of a faint median keel; apex occasionally faintly projecting. Ovipositor ( Fig. 7 View FIGURE 7. A – H V) rather short, apex dentate.

Coloration. Male. Light form: Green, stippled with black. Antennae yellow. Pronotum with red cuneate lateral spots in metazona. Tegmina yellow, discus infumate. Abdominal tergites uniformly green or with indication of two white dorso-lateral bands; occasionally with small black spots at the base of some tergites. Cerci yellow.

Dark form: Body green, legs brown. Antennae infumate. Vertex largely black. Discus of pronotum with red anterior margin and red lateral bands, ornated mediad by black lateral bands; posterior margin black or red; sulcus black; remaining part of metazona whitish green or yellowish brown. Tegmina as above. Abdominal tergites with a median and two lateral black bands, the lateral often interrupted before posterior margin of tergites; space between lateral and median bands nearly white. Epiproct yellowish green or partly black.

Female. Light form: Uniformly green. Metazona of pronotum with narrow red lateral stripes, bordered externally by a white stripe. Antennae and tegmina yellow.

Dark form: Similar to male, but black markings slightly less extended. Anterior and posterior margins of pronotum red or green; discus between lateral dark markings green.

As in the preceding species, the dark colour variant appeared in specimens that were bred from the egg in laboratory. Transient forms were found in the field.

Etymology. The new subspecies is named after its distribution in the Dinaric Alps.

Distribution. Presently known from Montenegro, Bosnia and southwest Serbia.

Stridulation ( Fig. 11 View FIGURE 11 D): Stridulation was mainly heard in the evening and early night. It is monosyllabic. Compared with the preceding species and P. affinis from eastern Serbia, the initial "sss" is almost suppressed ( Tab 6 View TABLE 6 ). The syllable consists thus mainly of the final "zip". The main frequency is at about 17 kHz. Often a variable number of syllables are repeated in short intervals to form loose sequences.
