Psorodonotus hakkari Kaya, Korkmaz & Çıplak sp. n.

( Figs 1 , 5 , 9, 15 , 21, 27, 33, 39, 45, 51, 57–61; Tables 1–4 )

Material examined. Holoype. Male; TURKEY – Hakkari , Yüksekova, 37° 51.998 N, 44° 38.358 E, 1902 m, 11.07.2009 (Coll. E.M. Korkmaz, M. Budak & M. Yıldırım) (AUZM); Paratypes. 7 males and 6 females; same data as holotype.

Diagnosis. This new species is belonging to the Venosus Group and within the species group show affinities with P. rugulosus and P. tendurek sp. n. by the slender and the long male cerci and comparatively less rugose pronotal disc of the female. This species is possibly the largest in the group in sizes of pronotum and hind femur in male and female, tegmina in male and ovipositor in female ( Figs 57–59 ). Although geometric morphometric analysis of male cerci put the new species with P. rugulosus in a clustered, P. hakkari sp. n. differs from this species by the pronotum, hind femur and ovipositor. Genetic data were not presented here, but, genetic data suggest that P. hakkari sp. n. and P. tendurek as sister species in phylogroup with P. rugulosus . P. hakkari sp. n. differs from its sister species P. tendurek sp. n. by the longer pronotum, hind femur and ovipositor and the outcurved male cerci. Genetic data also support its uniqueness.

Etymology. Named after its type locality Hakkari province located on north-west part of Zagros Range in the most east of Turkey.

Description

Male (holotype). Over medium sized for the genus and for the group. Fastigium of vertex rounded, roughly 3.57–5 times as wide as scapus.

Thorax. Pronotum ( Fig. 9 ) long, at least one and half of first tibia, gradually widened backward; disc of pronotum flattened and slightly depressed in the middle, with rounded lateral margins, widely rounded hind margin and with distinct tubercles in whole surface; paranotal lobes with weak tubercles; tegmina reach to end of the third abdominal tergite and covered by pronotum up to its half ( Figs 9 , 21). The stridulatory file has comparatively dense pegs, the peg number varies between 148 and 178. Hind femora reach to tip of the abdomen ( Fig. 5 A).

Abdomen. Cerci (Fig. 33) comparatively long for the group; with a short and apically outcurved tooth; wide prior to tooth, getting narrower after it. Tenth tergite (Fig. 27) transverse and with a wide medial projection. Subgenital plate as in genus, with a shallow triangular incision and rounded apical lobes; styli small. Titillarors (Fig. 39) as in the species group, basal arms almost twice of apical arms and apical arms with spines along a margin dorsally.

Colouration. General colouration olive green. Dorsal of head and disk of pronotum blackish or marginally olive green. Paranota dark olive green dorsally and dirty yellow or greenish yellow at margins. Tegmina brown with yellow veins. Femora and tibiae olive green, hind femur blackish green dorsally, tarsi reddish. Abdomen pale dark olive-green. Cerci yellowish brown.

Female. Disc of pronotum ( Figs 5 B, 15) with rounded lateral margins, slightly swollen in prozona, flattened and widened in metazona, with a concave hind margin; its surface with less prominent tubercles when compared to male. Pronotal lateral plates as in male. Tegmina fully covered by pronotum, reduced to scale-like appendages. Hind femora do not extend to end of abdomen ( Fig. 5 B). Subgenital (Fig. 51) plate short, incised medially at hind margin with rounded apical lobes slightly narrowing apicalward. Ovipositor (Fig. 45) robust when compared to other members of the group; long, roughly twice of pronotum in length. Colouration: totally olive green, with black spots at the base of abdominal terga, tarsi reddish as in male.

Distribution. The new species occurs in alpine zone of Mountains located on north-west part of Zagros Range in Hakkari Provinces of Turkey ( Fig. 1 ).
