Description. Holotype, ♀, length of body 5.6 mm, of fore wing 5.6 mm.
Head. Transverse, width of head 1.6 × its lateral length ( Fig. 8I View FIGURE 8 ); antenna with 73 segments, third segment (including annellus) 0.9 × longer than fourth segment, length of third, fourth and penultimate segments of antennal 2.0, 2.8 and 2.5 × as long as their width, respectively ( Fig. 8I View FIGURE 8 ); length of maxillary palp 1.7 × height of head; eye glabrous, 1.5 × as long as temple in dorsal view ( Fig. 8I View FIGURE 8 ), eye in lateral view 1.3 × higher than wide ( Fig. 8K View FIGURE 8 ); frons flat ( Fig. 8I View FIGURE 8 ); vertex rather convex ( Fig 2I View FIGURE 2 ); OOL:diameter of ocellus:POL= 8:3:3; face 2.1 × wider that high, densely and coarsely rugose-reticulate with transverse striation laterally ( Fig. 8J View FIGURE 8 ); clypeus small, subtriangular, protruding forward, densely and finely reticulate-punctate ( Fig. 8J View FIGURE 8 ); malar space absent; mandible rugose and with 4 teeth or lobes, lateral teeth large and lobe-shaped ( Fig. 8L View FIGURE 8 ), ventral carina protruding, middle tooth medium-sized ( Fig. 8M View FIGURE 8 ); medial length of mandible 1.6 × its maximum width.
Mesosoma. Length of mesosoma 1.6 × its height ( Fig. 8D View FIGURE 8 ); pronope deep and medium-sized, side of pronotum largely smooth ( Fig. 8D View FIGURE 8 ); mesoscutum with lateral carina in front of tegulae; epicnemial area crenulated; precoxal sulcus long and crenuated, reaching middle coxa; pleural sulcus weakly crenulate; episternal scrobe round and shallow, remainder of mesopleuron smooth; metapleuron punctate and with a round pit anteriorly ( Fig. 8D View FIGURE 8 ); notauli distinctly impressed on disc, crenulated and wide, with deep and wide medio-posterior depression; mesoscutum glabrous ( Fig. 8C View FIGURE 8 ); scutellar sulcus finely crenulate, sulcus 3.0 × wider than its maximum length ( Fig. 8C View FIGURE 8 ); scutellum and its side smooth, and with long setose posteriorly; surface of propodeum finely punctate and areola absent ( Fig. 8E View FIGURE 8 ).
Wings ( Figs 8 View FIGURE 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 View FIGURE 8 ); 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 View FIGURE 8 ); 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 View FIGURE 8 ).
Colour. Yellowish brown ( Fig. 7 View FIGURE 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”.
