Diagnosis: The female of P. diyarbakirensis can be separated from the species of the subgenus Umbripennis by the distinctly striate propodeal declivity ( Fig. 10 ) in combination with a complete dull and punctate clypeus ( Fig. 12 ). Additional diagnostic features are discussed in the Remarks section below.

Description of female holotype: Body length 13.6 mm. Colour. Black with the following parts red: apex of mandible, T1 and S1 apart of basal third, T2 and S2 completely, basal 2/3 of T3, base of S3. Lower face between antennal base and eye and mandible basally with fine grey pubescence. Long pilosity of body black, some setae of propodeal declivity, T1 and T6 pale. Wings dark infuscate. Morphology: ACM straight, clypeus with fine and dense punctation and some larger punctures apico-medially, interspaces dull. ACM with narrow impunctate lamella ( Fig. 11 ). AS 3 1–2x as long as AS 1+2 combined ( Fig. 12 ). Inner eye margin somewhat divergent below. OOL = 1.7x POL. Frons, pronotum and mesoscutum finely grainlike punctuate, without interspaces. Scutellum and metanotum with sparser punctation and shiny interspaces, some interspaces as large as puncture diameter. Metapostnotum 0.9x as long as metanotum, with five fine rugae. MIM triangular with obtuse angle, reaching middle of metapostnotum, its ground shiny ( Fig. 9 ). Propodeal dorsum finely puncto-striate, propodeal declivity with distinct but fine crosswise striation, including about 20 striae ( Fig. 10 ). Interspaces of striation zone shiny, contrasting to duller propodeal dorsum. Hindtibia above with eleven large scales, first four scales bear a pale bristle, remaining scales bear a dark spine. Next to the scales on the outside of the tibia with four smaller scales basally, bearing a short spine. Remaining part of hindtibia with spines only next to hindtibia. Frons, head below, pronotum, prosternum, and forecoxa with long and dense black bristle-like pilosity, setae on avarage as long as AS 1. Forefemur, mid and hindcoxa also with long black setae, pilosity shorter and more scattered than of previous parts. Mesoscutum and clypeus with a few setae. Midfemur with 7–8 black curved setae, longest setae as long as half diameter of midfemur. Propodeum laterally and on declivity with numerous long black setae, base of T1 laterally with a few short pale setae. Sternites apically with a few long setae, T6 and S6 with pale erect and semierct setae. Last hindtarsomere without spines below.

Variation in paratypes: The extent of red colour of T3 is variable. Usually, T3 is red in basal 2/3. Two specimens have T3 all black, in another two is it all red. Some females also have a weaker striation of propodeal dorsum, compared with the holotype. Body size ranges between 10.0–14.0 mm.

Description of male paratype: Body length 9.8 mm. Colour. Black with the following parts red: T1 and S1 apart basal half, T2 and S2 completely, basal 2/3 of T3, basal part of S3 ( Fig. 13 ). Face near lower inner eye margin and clypeus laterally with grey short pubescence, pilosity of head and mesosoma brown to light brown. Morphology: clypeus, frons, mesosoma etc. similar to female. Metapostnotum somewhat longer than metanotum, with five striae, MIM deeply triangular. Propodeal dorsum with indistinct longitudinal impression, propodeal declivity with irregulare striation, interspaces finely net-like sculptured. S5 and S6 with a few erect setae. S8 apically rounded ( Fig. 14 ), underside baso-medially with 2–3 rows of long setae, apically distinctly meandered ( Fig. 15 ). Remaining underside of S8 with erect setae, laterally and basally shorter than basally, apically as long as basally. Longest meandered setae nearly as long as AS 1. Genitalia as in Fig. 14 .

Distribution: Eastern Turkey.

Etymology: The name is derived from the area of origin of the holotype. Diyarbakır is a province in southeast- ern Turkey.

Remarks: Priocnemis diyarbakirensis sp. nov. was collected with 72 female paratypes from different localities. For this reason it is surprising that the species has not yet been reported from Turkey before. Probably the species was earlier confused with P. fallax or any other of the Turkish species. There is one male amoung 72 females, collected together with some females. Because of its unknown but distinct character combination is it treated as the male of the species. Other described male taxa from Turkey can be excluded here.

This new species is similar to P. fallax Verhoeff, 1922 and differs by the characters given in the table below ( Table 1, females).

ACM with narrow and dull lamella, remaining clypeus ACM with polished and shiny lamella, area above lamella densely punctuate, interspaces dull ( Fig. 11 ). with some shiny interspaces.

Pilosity of vertex, forecoxa and pronotum generally shorter Pilosity of vertex, forecoxa and pronotum generally longer and sparser, setae thinner compared to P. fallax , best seen in and denser, setae thicker compared to P. diyarbakirensis sp. direct comparison nov.

MIM triangular, right angled or with obtuse angle ( Fig. 9 ). MIM large, bandlike, as wide as 2–3x length of metapostnotum

Propodeal declivity (and apical fourth of propodeal dorsum Propodeal declivity without or with very fine and indistinct in some specimens) with distinct crosswise striation, inter- striation, declivity dull (some specimens from Greece also spaces of declivity shiny, contrasting with dull propodeal have distinct striation, and differ by remaining characters dorsum ( Fig. 11 ). given here)

each with a small spine.

Another species from Turkey is P. fahringeri Wolf, 1963 . It shares the smooth hindtarsomere V (without short spines below) and striated propodeal declivity with P. diyarbakirensis sp. nov. and can be recognized by a dense pilosity of midfemur below (about 20 setae in P. fahringeri , and only 8–9 setae in P. diyarbakirensis sp. nov). MIM of P. fahringeri is also different and lacks the medial impression, or is only weakly impressed, while it is distinctly triangulary impressed in P. diyarbakirensis sp. nov. Generally P. fahringeri has a denser pilosity on head and mesosoma, compared to other species.

The male of P. diyarbakirensis sp. nov. is characterized by a special pilosity of S8, in combination with a red abdominal base and a distinctly striate propodeal declivity. S8 has long and apically meandered setae basomedially ( Fig. 15 ). This kind of pilosity can also be found at P. sulci Balthasar, 1943 (large species, at least 14 mm, and propodeal declivity without striae, recorded from eastern Europe and Central Asia, not yet from Turkey) and at P. damascenus Wolf, 1962 , described from Syria. The latter has an all black abdomen and the, MIM is weakly impressed with a medial longitudinal furrow, whereas the MIM is deeply and triangulary impressed in the male of P. diyarbakirensis sp. nov. like in the female.
