Diagnosis.

Ocelli comparatively small; upper condyles of mandibles near lower level of eyes; antenna of ♀ with ca. six moniliform apical segments (Fig. 150 ); inner tooth of mandible 0.6-0.8 × as long as apical tooth (Fig. 151 ); parastigma large and yellow; vein r of fore wing 1.2-2.3 × vein 3-SR of fore wing (Fig. 141 ); third tergite more or less obtuse apically in lateral view or with transverse depression, finely sculptured and matt medially, comparatively short; area of mesosternum near mesosternal sulcus rather matt and distinctly granulate (Fig. 138 ); temple narrowed ventrally; hind femur of ♂ moderately inflated (Fig. 139 ). Very similar to the Central Asian and East Mediterranean P. parva Kokujev, 1903, but P. granulata has mesosternum distinctly granulate and rather matt (shiny and superficially granulate in P. parva ), hind femur of ♂ moderately inflated (strongly inflated), vein 1-M of fore wing pale yellow (dark brown), vein 1-R1 of fore wing approx. as long as pterostigma (distinctly shorter), marginal cell of fore wing rather slender (wider), parastigma of fore wing wide (rather small) and apical antennal segments of ♀ moniliform (non-moniliform).

Description.

Female, holotype, length of body (excluding ovipositor) 2.8 mm; antenna 2.0 mm; fore wing 2.2 mm; visible part of ovipositor sheath 0.4 mm (only apex with few setae).

Head. Width 1.5 × median length in anterior view and part of head above eye in lateral view 0.3 × height of eye (Fig. 149 ); antenna with 23 segments and as long as fore wing, near its apical third segments elongate and longer than wide, narrowed apically and six apical segments moniliform (Figs 146 , 150 ) and apical segment with minute spine, third, fourth and penultimate segments 3.0, 2.5 and 1.5 × longer than wide in lateral view, respectively; area of stemmaticum granulate; OOL: diameter of posterior ocellus: POL = 20: 6: 7; length of eye 1.9 × temple in dorsal view (Fig. 147 ); frons granulate and matt laterally, superficially granulate medially and rather shiny, without median carina; vertex granulate, posterior rugulose-granulate and matt; temple granulate and matt; face granulate and with small median bump dorsally but no distinct median carina; clypeus smooth, shiny and distinctly narrower than face and with three minute teeth medio-ventrally (Fig. 148 ); eye large, strongly convex and in lateral view 1.3 × (measured medially) as wide as temple (Fig. 149 ), in anterior view its height 0.8 × minimum width of face; upper condyle of mandible near lower level of eyes (Fig. 148 ); malar space granulate, with satin sheen and 0.8 × as long as basal width of mandible; lower tooth of mandible 0.7 × as long as apical tooth (Fig. 151 ).

Mesosoma (Figs 138 , 142 ). Length 1.6 × its width in lateral view; side of pronotum largely coarsely rugose; propleuron posteriorly evenly convex; mesosternum densely granulate and rather matt; mesoscutum densely granulate, but medio-posteriorly rugulose-granulate; scutellum flat, distinctly granulate and rather matt; notauli not indicated; scutellar sulcus narrow and with nine carinae (Fig. 142 ); metanotum with short median carina anteriorly and no tooth posteriorly; propodeum coarsely reticulate-rugose, without distinct median and transverse carinae, and latero-posteriorly not tuberculate. Wings. Fore wing 2.8 × longer than its maximum width; length of 1-R1 as long as pterostigma; distance between wing apex and vein 1-R1 0.7 × length of vein 1-R1; r issued far beyond middle of pterostigma and 1.8 × 3-SR; 2-SR nearly straight and distally slightly converging to posterior margin of pterostigma (Fig. 141 ); SR1 nearly straight; 2-SR+M present, m-cu postfurcal; parastigma rather large; first discal cell of fore wing higher than first subdiscal cell; 1-CU1 0.5 × as long as vein 2-CU1; r:3-SR:SR1 = 7:4:39; 2-SR:3-SR:r-m = 21:4:8; r-m vertical; 2-M slightly curved (Fig. 141 ). Hind wing: M+CU:1-M:1r-m = 27:19:10. Legs. Hind femur matt, 4.1 × as long as wide and slightly widened submedially; middle tibia with weak ivory blister; inner spur of middle tibia 0.4 × its basitarsus; hind tibia slender (Fig. 145 ); hind coxa largely superficially coriaceous and with satin sheen.

Metasoma (Figs 143 , 144 ). Elliptical in dorsal view, 1.9 × as long as wide and 1.4 × as long as mesosoma; first and second tergites densely and finely longitudinally rugose; metasomal sutures medium-sized; third tergite distinctly convex medially, 1.5 × longer than second tergite and laterally curved, in lateral view rather convex, largely densely rugulose and with satin sheen (Fig. 144 ), lateral lamella narrow laterally, not protruding latero-apically and medio-apically truncate and medium-sized and area above it concave; ovipositor sheath narrow (Fig. 144 ), its visible part 0.2 × as long as fore wing and 0.3 × metasomal carapace and only its apex with few medium-sized setae; hypopygium apically with short robust triangle, without apical spine, and densely setose.

Colour. Yellowish brown; apical half of antenna and stemmaticum more or less darkened; ovipositor sheath (but paler basally), veins 1-CU1, 2-CU1, r, 2-SR and 2-M of fore wing brown; clypeus, mandible (except dark brown teeth), palpi, propleuron, pronotal side ventrally, tegulum and humeral plate, legs (but hind femur rather brownish except basally and hind tibia subbasally and apically slightly darkened), first and second tergites and metasoma ventrally pale yellow; pterostigma (but basally partly pale yellowish) dark brown; parastigma, veins 1-M and m-cu of fore wing pale yellow; wing membrane basally and marginal cell subhyaline, remainder of apical half of fore wing slightly brownish.

Male.

Similar to female, but hind femur rather inflated (Fig. 139 ) and antennal segments slender and elongate (Fig. 140 ).

Variations.

Length of fore wing of ♀ 1.5-2.5 mm, of ♂ 1.9-2.2 mm; inner tooth of mandible robust and 0.6-0.8 × as long as apical tooth.
