Type material.

Holotype, ♀ (RMNH): " United Arab Emirates, NARC near Sweihan (1193), light trap, 14-28.iii.2005, 24°24'N, 55°26'E, A. v. Harten, RMNH’05”. Paratypes: 3♀: Idem, 28.iii.-2.iv.2005; 1♀: "United Arab Emirates, Fujairah (1314), light tr[ap], 13-19.iv.2005, 25°08'N, 56°21'E, A. v. Harten, RMNH’05”.

Diagnosis.

Ventral half of temple very shiny, mostly smooth to largely finely aciculate (Fig. 273 ); clypeus very shiny and 0.9 × width of face, intertentorial distance 4 × minimum distance from clypeus to eye (Fig. 272 ); POL 0.6-0.8 × diameter of posterior ocellus; median carina of frons present; subapical antennal segments somewhat serrate (because of minute subapical protuberances) and non-moniliform (Figs 274 , 275 ); eye in lateral view ca. 2.5 × as wide as temple medially (Fig. 273 ); vein 1-R1 of fore wing approx. twice distance between apex of marginal cell and apex of wing (Fig. 265 ); frons with fine median carina; temple rather flat (Figs 271 , 273 ); stemmaticum yellowish brown; length of fore wing approx. 2.5 mm. Similar to P. glabritemporalis because of the smooth face and temples, but differs by having temples directly narrowed behind eyes (convex in P. glabritemporalis ), clypeus with two minute ventral teeth (3), second metasomal suture curved (straight), stemmaticum yellowish brown (largely dark brown), scutellar sulcus narrow (wide) and slender hind femur (widened).

Head. Width 1.5 × median length in anterior view and part of head above eye in lateral view 0.3 × height of eye (Fig. 273 ); antenna with 23 segments, with small apical spine and as long as fore wing, segments slender and gradually shortened, narrowed apically and segments of apical half with minute subapical protuberance, “pseudo-serrate”, and non-moniliform (Fig. 275 ), third, fourth and penultimate segments 3.4, 2.8 and 1.5 × longer than wide in lateral view, respectively; area of stemmaticum smooth; OOL: diameter of posterior ocellus: POL = 14: 5: 4; length of eye 2.6 × temple in dorsal view (Fig. 271 ); frons medially mostly smooth (except for fine median carina), very shiny and laterally finely curved rugulose; vertex superficially rugulose near eyes and remainder mostly smooth and shiny; temple parallel-sided in lateral view, mostly smooth (except some aciculae ventrally) and shiny, rather flat (Fig. 273 ), in dorsal view directly narrowed behind eyes (Fig. 271 ); face mostly smooth, very shiny and with short median ridge dorsally; clypeus 0.9 × minimum width of face, smooth and very shiny, with erect setae and medio-ventrally with two obsolescent teeth (Fig. 272 ); intertentorial distance 4 × minimum distance between clypeus and eye; eye large, strongly convex and in lateral view 2.5 × (measured medially) wider than temple (Fig. 273 ), in anterior view height nearly equal to minimum width of face; upper condyle of mandible above lower level of eyes (Fig. 272 ); malar space rugose, shiny and 0.3 × as basal width of mandible; lower tooth of mandible minute, 0.3 × as long as apical tooth (Fig. 270 ).

Mesosoma (Figs 264 , 266 ). Length 1.6 × its width in lateral view; side of pronotum mainly rugose and shiny; mesosternum superficially coriaceous and shiny; mesoscutum finely reticulate-rugulose and rather shiny; notauli absent; scutellar sulcus narrow and with eight short carinae (Fig. 266 ); scutellum finely longitudinally rugulose and rather shiny; metanotum with short median carina anteriorly, weakly serrate and truncate posteriorly; propodeum nearly smooth anteriorly and remainder finely rugose, without distinct median and transverse carinae, latero-posteriorly not tuberculate. Wings. Fore wing 2.8 × longer than its maximum width; 1-R1 as long as swollen pterostigma; 1-R1 2.3 × distance between apex of marginal cell and apex of wing; r issued far beyond middle of pterostigma and 0.8 × 3-SR; 2-SR straight and distally converging to posterior margin of pterostigma (Fig. 265 ); SR1 straight; 2-SR+M rather long because of distinctly postfurcal m-cu; parastigma large; 1-CU1 0.4 × as long as vein 2-CU1 and as long as cu-a; r:3-SR:SR1 = 9:20:130; 2-SR:3-SR:r-m = 26:20:11; r-m vertical; 2-M weakly curved (Fig. 265 ). Hind wing: M+CU:1-M:1r-m = 26:22:9. Legs. Hind femur 4.4 × as long as wide and slender (Fig. 269 ); middle tibia with ivory blister; inner spur of middle tibia 0.4 × its basitarsus; hind coxa mostly smooth and shiny; hind tibia and basitarsus slender (Fig. 269 ).

Metasoma (Figs 267 , 268 ). Oval in dorsal view, 1.7 × as long as wide and 1.2 × as long as mesosoma; first suture curved; first and second tergites finely and densely longitudinally striate-rugose, rather shiny; third tergite 1.5 × longer than second tergite and laterally curved, in lateral view rather convex (Fig. 268 ), but apically flat, finely striate-rugulose, rather shiny and medio-posteriorly truncate (Fig. 267 ), lateral lamella narrow, not protruding latero-apically and medio-apically narrow and truncate; ovipositor sheath medium-sized (Fig. 268 ), its visible and entirely setose part 0.05 × as long as fore wing and 0.11 × metasomal carapace; hypopygium rather obtuse apically, without short apical triangle or apical spine.

Colour. Brownish yellow (including stemmaticum); palpi, mandible (except reddish brown apex), clypeus, malar space, tegulae, pronotum, propleuron, legs (but hind femur and tibia brownish apically), first and second metasomal tergites and metasoma ventrally pale yellowish or ivory; ovipositor sheath brown; pterostigma rather dark brown, but basally and narrowly apically pale yellowish (Fig. 265 ); wing membrane subhyaline but below pterostigma slightly infuscate; parastigma, veins 1-M, 2-CU1 and m-cu of fore wing pale yellowish and veins r, 1-CU1, cu-a, 2-SR, 3-SR and 2-M brown.
