Wings (Figs 8 A-B). Pterostigma 3.9 × as long as wide, vein r issuing from posterior two thirds of pterostigma, r 0.6 × width of pterostigma; r: 3-SR: SR1= 5:18:52; m-cu of fore wing interstitial; 1-CU1:2-CU1 = 5:17; 3-CU1 much longer than CU1b; cu-a postfurcal; 2-SR:3-SR:r-m = 20:15:7; first subdiscal cell 3.0 × as long as wide; Hind wing: M+CU:1-M:1r-m = 20:15:12; m-cu present. Legs. Hind coxa with some punctures anteriorly; tarsal claws robust, shorter than arolium (Fig. 8N); length of femur, tibia and basitarsus of hind leg 5.0, 6.9 and 6.3 × their width, respectively; apical appendages of hind tarsal segments absent. Metasoma. Surface reticulate-rugose, length of first tergite 0.8 × its apical width; dorsal carinae united posteriorly, medially convex and dorsope distinct (Fig. 8F); median length of second tergite 0.8 × its anterior width, 0.7 × its maximum posterior width, 0.9 × length of third tergite; combined length of second and third tergites of metasoma 1.3 × maximum width; setose part of ovipositor sheath 0.56 × as long as fore wing (total visible sheath 0.58 ×), flattened and 1.6 × as long as hind tibia (Fig. 8H). Colour. Yellowish brown (Fig. 7); head, hind femur, hind tibia (except pale yellow basal one sixth) and third tergite of metasoma black; mandible brownish; palpi yellowish; pterostigma and veins brown; wing membrane slightly infuscated. Variation. Body length: 4.5–6.0 mm, length of fore wing 4.5–5.6 mm. Comparative diagnosis. This species is similar to H. hemiflava van Achterberg, but differs by having a vertical vein r-m of fore wing (versus inclivous in H. hemiflava); vein r 0.6 × maximum width of pterostigma (versus 0.9 ×); frons blackish anteriorly (versus frons brownish yellow or yellow anteriorly); ovipositor sheath 1.2 × as long as combined first–third metasomal tergites (versus nearly equal); base of second tergite dark brown, contrasting with yellowish remainder of tergite (versus base and apex similarly coloured). Etymology. Named “ verticalis ” because of the vertical vein r-m of the fore wing: “ verticalis ” is Latin for “upright”.
