Diagnosis.
Face (Fig. 12 View Figures 12–14 ) with dense punctures and yellow brown setae. Occipital carina reaching hypostomal carina distinctly above base of mandible, distance to base of mandible 0.5 as long as basal width of mandible. Fore wing vein 1cu-a distal to M&RS by 0.3 × length of 1cu-a. Areolet quadrate, receiving vein 2m-cu approximately 0.7 × distance from vein 2rs-m to 3rs-m. Median area of propodeum (Fig. 17 View Figures 15–17 ) with fine transverse wrinkles, laterally with fine punctures. Posterior portion of first tergite, tergites 2-3 and anterior portion of tergite 4 red to brownish red.
Description.
Body length 11.5-12.0 mm. Fore wing length 8.5-9.0 mm.
Head. Head 1.6 × as wide as length from lower margin of clypeus to upper margin of face. Inner margins of eyes slightly convergent ventrally. Face (Fig. 12 View Figures 12–14 ) 1.2-1.3 × as wide as long, shiny, evenly convex, with dense punctures (in lateral portion punctures sparser than upper median portion) and yellow brown setae. Clypeal sulcus weak, as vestige. Clypeus 2.5-2.6 × as wide as long, shiny, subbasal portion distinctly convex transversely, with sparse yellow brown setae; apical margin almost truncate. Mandible with sparse punctures and yellowish brown setae, upper tooth slightly longer than lower tooth. Malar space 1.1-1.2 × as long as basal width of mandible. Gena with sparse irregular fine punctures. Vertex (Fig. 13 View Figures 12–14 ) smooth, shiny, with sparse punctures. Stemmaticum with relatively dense punctures. Postocellar line 0.9 × as long as ocular-ocellar line. Ocular-ocellar line 1.4-1.5 × as long as maximum diameter of posterior ocellus. Frons (Fig. 13 View Figures 12–14 ) slightly concave, with dense brown setae and weak median longitudinal sulcus. Antenna stout, with 36-37 flagellomeres. Ratios of lengths from first to fifth flagellomeres: 10:8:8:7:7. Occipital carina complete, reaching hypostomal carina distinctly above base of mandible, distance to base of mandible 0.5 as long as basal width of mandible.
Mesosoma. Lateral concavity of pronotum (Figs 14 View Figures 12–14 , 15 View Figures 15–17 ) wide, smooth, shiny, lower anterior and dorsoposterior portions with distinct punctures and brown setae; subdorsal-median and lower posterior portions with distinct transverse wrinkles. Epomia vestigial. Mesoscutum (Fig. 13 View Figures 12–14 ) almost flat, shiny, with fine punctures and yellowish brown setae. Notaulus indistinct. Scutellum almost shiny, with fine punctures. Postscutellum transverse, slightly convex, with indistinct fine punctures. Mesopleuron (Fig. 15 View Figures 15–17 ) with even fine punctures; speculum and its surrounding area smooth and shiny. Upper end of epicnemial carina almost reaching to subtegular ridge. Metapleuron with even, fine punctures. Juxtacoxal carina absent. Legs stout. Outer profiles of tibiae with strong pegs (Fig. 11 View Figure 11 ). Ratios of length of hind tarsomeres from first to fifth approximately: 3.6:2.4:1.8:1.0:2.0. Claw simple. Fore wing 1.2-1.3 × as long as metasoma, brownish, hyaline. Vein 1cu-a inclivous, distal to M&RS by 0.3 × length of 1cu-a. Areolet quadrate, receiving vein 2m-cu approximately 0.7 × distance from vein 2rs-m to 3rs-m; postnervulus intercepted at lower 0.2-0.25. Hind wing vein 1-cu 0.2 × as long as cu-a. Propodeum (Fig. 17 View Figures 15–17 ) evenly convex, shiny, median area with irregular fine wrinkles, lateral areas with fine punctures; posteromedian portions almost smooth, sparsely punctate. Median longitudinal carina present as vestige anteriorly. Propodeal spiracle elongate, 2.3 × as long as maximum width.
Metasoma. Metasomal tergites (Fig. 18 View Figure 18 ) with even, fine punctures, evenly widened from base to fifth tergites. First tergite 1.5-1.6 × as long as posterior width, evenly widened posteriorly, anterior portion weakly punctate; spiracle slightly convex, located at anterior 0.3. Second tergite 0.8-0.9 × as long as posterior width. Third tergite 0.65-0.7 × as long as posterior width. Fourth tergite 0.55-0.60 × as long as posterior width. Lateral sides of fifth tergite parallel. Apex of ovipositor sheath slightly beyond apex of metasoma.
Coloration (Fig. 11 View Figure 11 ). Black, except for following: ventral profile of flagellum, apical half of clypeus, mandible except teeth, maxillary palpi, labial palpi, tegulae, legs except coxae, trochanters and hind tarsus, posterior portion of first tergite, tergites 2-3 and anterior portion of tergite 4 red to brownish red. Hind tarsus black. Pterostigma and veins brownish black.
Male.
Unknown.
Etymology.
The specific name is derived from the densely punctate face (Fig. 12 View Figures 12–14 ).

Differential diagnosis.
The new species is similar to Strongylopsis anomala Brauns, 1896, but can be distinguished from the latter by the following combination of characters: head 1.6 × as wide as length from lower margin of clypeus to upper margin of face; face (Fig. 12 View Figures 12–14 ) with dense punctures; areolet quadrate; propodeum with distinct transverse wrinkles; second tergite distinctly trapezoidal. Strongylopsis anomala : head at least 1.7 × as wide as length from lower margin of clypeus to upper margin of face; face with sparse fine punctures; propodeum without transverse wrinkles; second tergite square.
