Etymology: This new subspecies is dedicated to the young orthopterist Dr Dragan Chobanov. He has recently conducted impressive studies on Barbitistini and has assisted us by sending us specimens of P. orbelicus .

Diagnosis: In our opinion, in the southern part of its range (i.e. Antalya and Mug˘la Provinces), the P. luschani group is represented by a single species that includes three morphological units (MU-1, MU-2, and MU-3); the last unit is described here as P. luschani chobanovi ssp. nov. This subspecies clearly has genetic affinity to the nominate subspecies as both constitute a phylogroup; the existing data do not indicate reproductive isolation between the two. Apart from its genetic properties, P. luschani chobanovi ssp. nov. can be easily distinguished from other subspecies by its specific male cerci.

Description: For morphology see Table S1, Figures 9– 13 , 28 , 35–39 , 53–57 , 72 ; for song see Table 2 and Figures 80 , 82–84 .

Male: Head: fastigium of vertex well produced anteriorly with a groove, its lateral margins parallel or slightly converging, roughly 1.3 times wider than scapus.

Thorax: pronotum short, moderately constricted in prozona, metazona gradually but weakly widened backward and weakly raised; metazona covering the tegmina beyond cubital vein. Posterior margin of pronotum truncate or gently concave. Lower margin of pronotal lateral lobes slightly wavy with small, noselike projection in the frontal part. Tegmina reach to hind edge of first abdominal tergite. The stridulatory file has comparatively dense pegs, gradually increasing in size from the base and becoming largest in the middle of the file; with 100–196 pegs. Fore femora slightly longer than pronotum. Hind femora with ventral spinules.

Abdomen: cerci ( Figs 35–39 ) comparatively slender and long for the group; they are almost straight in the basal two-fifths to three-fifths and curved inward with a rectangle distally, constituting a typical ‘L’ shape; the distal part of cerci gradually tapering, especially from its outer margin; the apex ends with a single, hook-like robust denticle or sometimes with a second small accessory one at the base of the large one. Subgenital plate (see Figs 53–57 ) long, extending beyond the tip of cerci; with a triangular incision, margins of incision divergent along their total length or divergent distally then divergent over a short distance apically.

Coloration: general coloration green with several black dots especially on prozona, legs, and abdomen. Antennae whitish-green, annulated with dark rings. Head and pronotal dorsum with lateral and medial thin pale stripes. Dorsolateral corners of pronotum in metazona with big, reddish-pink spots almost touching each other at the hind margin. Tegmina yellow with dark brownish-black stridulatory area. Femora and tibiae dark green with several black dots. Abdomen green with three black stripes, one mediodorsally and each of the others dorsolaterally. Cerci reddish-brown, with black denticles.

Female: Pronotum almost cylindrical but slightly flattened and slightly widened in metazona and with a truncate or insignificantly concave hind margin. Pronotal lateral plates as in male and straight dorsally with a transverse sulcus cutting the median line just behind the middle of pronotum. Tegmina fully covered by pronotum, reduced to scale-like appendages. Subgenital plate short, transverse, widely oval, apically blunt. Ovipositor roughly one and a half times the pronotum in length, its apical part with short, stout teeth dorsally, ventrally, and laterally, as in allied species. Lamella (basal fold of dorsal margin of lower ovipositor valve; Fig. 72 ) short, flattened, and indistinctly widened laterally.

Coloration: as in the male.

Distribution: The new subspecies occurs over a wide altitudinal range starting nearly from sea level in the Es¸en Valley and extending to beyond 2000 m on Akdag˘ Mountain ( Table 1, Fig. 1 ). It occurs in openings amongst Mediterranean forest or maquis vegetation in the lowlands and in the alpine zone in the highlands.
