( Figs 1 View FIGURE 1 b, 2b, 3b, 4d, 5c, 6b, 7c)
Diagnosis. Mesoscutum reddish, except median lobe largely black, polished, almost without hairs; metapleuron coarsely rugose-punctate; propodeum with lateromedian longitudinal and posterior transverse carinae strong; fore and mid femora with median ventral tooth continuous with short median ventral carina; first abscissa of hind wing vein Cu 1 about 3.2x vein cu-a, second abscissa of vein Cu 1 distinct; ovipositor 0.85x hind tibia, up-curved at tip.
Description. (Holotype female). Body length 8.8 mm, fore wing 6 mm, ovipositor 1.7 mm. Head. Antenna with 30 flagellomeres, first flagellomere 1.4x length of second; diameter of lateral ocellus 1.15x ocellar-ocular distance; frons impunctate, polished; inner margins of eyes weakly concave above antennal sockets, parallel ventrally; face as high as wide, pubescent; clypeus convex, about 0.75x as high as wide, separated from face by impressed clypeofacial suture, apical margin round; malar space equal to basal width of mandible; mandible upper tooth slightly longer than lower tooth; palpi formula 5:4; occipital carina complete, meeting hypostomal carina about 1.5x basal mandible width from base of mandible, forming flange ventrally after meeting hypostomal carina.
Mesosoma . Pronotum and mesoscutum impunctate, polished; mesoscutum 1.35x as long as wide at anterior level of tegulae; scutellum strongly convex, pubescent, lateral carina present at base; mesopleuron densely setose except concave area near mesopleural suture bare and polished, epicnemial carina present on lower half of mesopleuron; metapleuron coarsely rugose-punctate, pubescent, submetapleural carina complete, forming small lobe anteriorly with some transverse ridges; propodeum moderately convex, dorsally bare, lateral longitudinal, lateromedian longitudinal and posterior transverse carinae present, many transverse striations attached to lateromedian and lateral longitudinal carinae, petiolar area convex medially, pleural area rugose, pubescent. Legs with fore and mid femora swollen, each with obtuse, compressed median ventral tooth; ventral face of fore and mid tibiae with carina from base extending nearly to apex; hind leg with femur 4.3x as long as wide, length 0.75x tibia, tibia 10x as long as apical width; basitarsus 0.3x tibia, 0.35x tarsus, 1.5x second tarsomere, fifth tarsomere swollen, slightly longer than third. Fore wing with vein Rs & M opposite cu-a, vein cu-a strongly inclivous, 2 rs-m about 0.8x distance between 2 rs-m and 2 m-cu, vein Cu 1 a separated from 1 m-cu by 1.25x length of vein Cu 1 b; hind wing with vein M+Cu strongly curved, first abscissa of vein Cu 1 3.2x as long as vein cu-a, second abscissa of vein Cu 1 pres- Metasoma. Tergites polished, with scattered short hairs; first tergite 1.7x as long as apical width, dorsolateral carina complete, median longitudinal carina extending over oblique groove; second tergite 0.8x length of first tergite, 0.95x as long as apical width, basal and apical oblique grooves deep, rhombic area convex; third tergite shorter than second, basal and apical oblique grooves moderately deep; first sternite rugose, extending to level of spiracle, round convex apically; ovipositor slightly up-curved at tip, length from tip of hypopygium 0.85x as long as hind tibia.
Colour. Black. Antenna black, except scape and pedicel yellow ventrally; mandible, palpi, tegula, subalar prominence, fore and mid legs yellow; hind tibia with subbasal and apical fuscous bands, hind tarsus with tarsomeres 1–4 apically and fifth tarsomere black; mesosoma reddish brown, except median lobe of mesoscutum, pronotum mediodorsally and mesosternum black; wings hyaline, pterostigma and veins brownish yellow; tergites brown to blackish brown; ovipositor brown.
Male. Unknown.
Comparison. This species belongs to the quadrisculpta group ( Townes & Townes 1960). It is similar to A. quadrisculpta (Gravenhorst) in having a pronounced medioventral tooth on the fore and mid femora. The new species can be distinguished from the latter by its longer ovipositor (0.85x hind tibia versus 0.3–0.5x), hind wing with first abscissa of vein Cu 1 3.20x vein cu-a (versus 2–2.3x), second abscissa of vein Cu 1 distinct present.
Etymology. This species is named after the teardrop-shaped black mark on the mesoscutum.
Distribution. Currently known only from Chu Mom Ray NP, Kon Tum Province, Central Highlands of Vietnam ( Fig. 8 View FIGURE 8 ).
