Type material.

Diagnosis.

Hypopygium of ♀ straight apically (Figs 167 , 171 ), without up curved apical triangle or spine-like protuberance; apical quarter of ♀ antenna more or less serrate in lateral view because of small subapical protuberances on segments, sixth segment subapically narrowed (Fig. 178 ); intertentorial distance of clypeus ca. 3 × minimum distance between clypeus and eye, clypeus 0.9 × wider than face and rather shiny (Fig. 175 ); inner tooth of mandible medium-sized (Fig. 177 ); propleuron transversely rugose; first discal cell of fore wing very wide anteriorly (Fig. 168 ); vein r of fore wing 0.2 × vein 3-SR and angled with vein 3-SR (Fig. 168 ); vein 2-SR of fore wing curved; vein cu-a of fore wing 0.8-0.9 × vein 1-CU1 and moderately oblique (Fig. 168 ); middle tibia very slender (Fig. 167 ); hind femur and tibia of ♀ and tarsal claws robust (Figs 167 , 172 ). Similar to P. ocularis because of size of ocelli and anteriorly wide first discal cell of fore wing, but with slender middle tibia, straight apex of hypopygium, rugose propleuron and elongate apical antennal segments in female.

Mesosoma (Figs 167 , 169 ). Length1.4 × its width in lateral view; side of pronotum largely rugose, but dorsally granulate; propleuron convex and transversely rugose, rather shiny; mesosternum granulate and matt; mesoscutum finely reticulate-rugose and rather shiny; notauli slightly indicated anteriorly; scutellar sulcus wide medially, with 6 carinae (Fig. 169 ); scutellum densely rugulose-granulate (smooth apically), convex and rather shiny; metanotum with short median carina anteriorly and with minor protrusion medio-posteriorly; propodeum coarsely reticulate-rugose on rugulose background, without distinct median and transverse carinae, latero-posteriorly not tuberculate. Wings. Fore wing 2.7 × longer than its maximum width; length of 1-R1 1.5 × as long as pterostigma; r issued rather far beyond middle of pterostigma and 0.2 × 3-SR; distance between 1-R1 and wing apex 0.4 × 1-R1; 2-SR distinctly bent and distally parallel with posterior margin of pterostigma (Fig. 168 ); SR1 curved; m-cu sub-interstitial; parastigma very large and first discal cell wide anteriorly (Fig. 168 ); 1-CU1 0.35 × as long as vein 2-CU1, cu-a distinctly inclivous and 0.9 × as long as 1-CU1; r:3-SR:SR1 = 5:22:57; 2-SR:3-SR:r-m = 28:22:8; r-m reclivous; 2-M oblique, weakly curved (Fig. 168 ). Hind wing: M+CU:1-M:1r-m = 19:17:10. Legs. Hind femur widened medially and 3.4 × as long as wide (Fig. 172 ); middle tibia slender and with small blister; inner spur of middle tibia 0.6 × its basitarsus; hind coxa superficially granulate and with satin sheen; hind tibia wide medially (Fig. 172 ); tarsal claws medium-sized.

Metasoma (Figs 170 , 171 ). Oval in dorsal view, 1.7 × as long as wide and 1.2 × as long as mesosoma; first and second tergites coarsely longitudinally rugose; third tergite 1.4 × longer than second tergite and laterally curved, convex, densely reticulate-rugose and medio-posteriorly truncate (Fig. 170 ), lateral lamella narrow, but wider latero-apically and medio-apically truncate; ovipositor sheath hardly widened apically (Fig. 171 ), its visible part 0.08 × as long as fore wing and 0.12 × metasomal carapace, its setae erect and mainly near apex of sheath; hypopygium apically acute, densely setose, without short up curved triangle or apical spine (Fig. 171 ).

Colour. Pale brownish yellow (including tegulum, but humeral plate partly dark brown); palpi, mandible (except dark brown teeth), clypeus, malar space, prothorax, legs (but telotarsi and hind tibia apically and subbasally brownish), first and second metasomal tergites (except laterally) and basal half of metasoma ventrally whitish or ivory; ovipositor sheath apically brown; stemmaticum and scutellum laterally dark brown; parastigma largely, pterostigma medially dark brown, but basally and narrowly apically pale yellowish (Fig. 168 ); wing membrane subhyaline but below dark part of pterostigma slightly infuscate; parastigma and vein m-cu largely pale yellow; apical half of metasoma, veins 1-M, 1-CU1, base of 2-CU1, r, 2-SR basally, 2-M and 3-SR of fore wing dark brown.
