Diagnosis

Clypeus with three comparatively large and slender teeth ( Fig. 1D ); temple truncate dorsally in lateral view ( Fig. 1C ); malar space large, 1.4 × as long as basal width of mandible ( Fig. 1D ); hypopygium with robust and short triangular protuberance ( Fig. 1I ); vein 2-SR of fore wing strongly curved and converging to posterior margin of pterostigma ( Fig. 1F ); length of 1-R1 of fore wing 1.5× as long as pterostigma ( Fig. 1F ).

Etymology

Named after the diagonally striate face, from the Latin ‘ acclivis ’ for ‘slope’ and ‘ rugata ’ for ‘wrinkled’.

COLOURATION. Yellow; stemmaticum, mandible apically, veins 1-CU1, cu-a and 1-1A of fore wing, pterostigma and parastigma of fore wing partly dark brown; mesosoma largely dark brown; mesosternum with M-shaped pale patch, scutellar sulcus, scutellum and propodeum apically yellow; metasoma largely dark brown; first and second tergites medially and laterally yellow; hind femur and tibia apically dark brown; first segment of antenna laterally, frons medially, temple basally and hind tibia basally brown.

HEAD. Width 1.3× median length in anterior view ( Fig. 1D ) and part of head above eye in lateral view 0.3× height of eye ( Fig. 1C ); antenna with 23 segments and 1.3× as long as fore wing, six subapical antennal segments moniliform ( Fig. 1E ), shortened and narrowed apically, third, fourth and penultimate segments 1.3, 1.0 and 1.6 × as long as wide in lateral view; area of stemmaticum mainly granulate; OOL: diameter of posterior ocellus: POL=32: 14: 8; eye 1.5× temple in dorsal view ( Fig. 1B ); frons with longitudinal rugae medially, rugose laterally and without median carina; vertex transversely rugosestriate and with satin sheen; temple largely striate and rather shiny; face transversely or obliquely rugose and without distinct median ridge; clypeus mostly smooth, shiny and as wide as minimum width of face, intertentorial distance 2.6× minimum width between clypeus and eye, clypeus long erect setose and with 3 distinct robust teeth medio-ventrally ( Fig. 1D ); eye medium-sized, in lateral view 1.3 × as wide as temple ( Fig. 1C ), in anterior view height of eye 0.8× minimum width of face; upper condyle of mandible relatively close to lower level of eyes ( Fig. 1D ); malar space 1.4× as long as basal width of mandible; lower tooth of mandible 0.2× length of apical tooth, robust ( Fig. 1K ).

MESOSOMA ( Fig. 1G ). Length 1.5 × its width in lateral view; side of pronotum mainly rugose, but dorsally nearly smooth; mesoscutum densely rugose and rather shiny, densely setose; notauli hardly indicated; scutellar sulcus wide and with nine carinae ( Fig. 1G ); scutellum triangular, flat, distinctly granulate and rather shiny; metanotum with short median carina anteriorly and small tooth protruding posteriorly; propodeum coarsely reticulate-rugose, with transverse carina, no median carina, latero-posteriorly tuberculate.

WINGS. Fore wing 2.7× as long as 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 0.3× 1-R1; 2-SR strongly curved and converging to posterior margin of pterostigma ( Fig. 1F ); SR1 slightly bent; 2-SR+M present; parastigma large; 1-CU1 0.4 × as long as vein 2-CU1, cu-a strongly inclivous and 0.8× as long as 1-CU1; r: 3-SR:SR1 =4: 17: 49; 2-SR: 3-SR: r-m= 23:17: 6; 2-M weakly curved ( Fig. 1F ).

LEGS ( Fig. 1J ). Hind femur with satin sheen, 4.3 × as long as wide and rather widened submedially; hind tibia rather swollen ( Fig. 1J ); middle tibia with medium-sized yellowish blister; hind coxa smooth and shiny.

METASOMA ( Fig. 1H–I ). Carapace elliptical in dorsal view, 1.9 × as long as wide and 1.1× as long as mesosoma; first and second tergites coarsely and densely longitudinally rugose; second suture narrow; third tergite 1.9× as long as second tergite and laterally weakly curved, in lateral view slightly convex anteriorly, in dorsal view convex medially, densely and coarsely rugose and rounded ( Fig. 1H ), lateral lamella narrow and posteriorly rather wide, not protruding latero-apically and medio-apically emarginate; ovipositor sheath narrow and parallel-sided, with some long and erect setae; hypopygium apically robust, no spine, but with short up-curved and setose triangle ( Fig. 1I ).

VARIATION. Length of fore wing of female 4.4–5.2 mm, of male 4.0 mm; third tergite 1.6–1.9× as long as second tergite, curved to nearly straight laterally; second tergite dark brown laterally to entirely so; POL 0.6–0.7× as long as diameter of posterior ocellus; eye medium-sized and in lateral view 1.3–1.4 × as wide as temple; vein 2-SR of fore wing curved to bent.
