Diagnosis
Supra-antennal elevations 0.1–0.4 times as long as scapus and outer side of elevations oblique and art least partly yellow (Fig. 454); occipital carina comparatively wide medio-dorsally (Fig. 454); head posteriorly with extensive yellowish or orange-brown pattern, including a V-shaped yellow or orange pattern behind stemmaticum (Fig. 454); head dorsally often densely reticulate-punctate (Fig. 454); temple dorsally coarsely reticulate-punctate (Fig. 457); mesopleuron largely black, without pale pattern (Fig. 459), at most with orange patch medio-dorsally; middle lobe of mesoscutum coarsely reticulate-punctate (Fig. 458); scutellum black medio-anteriorly and medially (Fig. 458); anterior half of fore wing more or less brown, with a less isolated patch (Fig. 456); protuberance of second metasomal sternite truncate, not protruding behind apical margin of sternite and posteriorly concave (Figs 461, 462), in female resulting in circular or rectangular opening between second and following sternites in lateral view (Fig. 461); third sternite of female subtruncate apically in lateral view (Fig. 461); third–fifth tergites with continuous yellow band posteriorly; sixth tergite largely yellow (Fig. 462).
Description
Redescribed after the female from Fujian, length of body 12.7 mm (of fore wing 10.3 mm).
Head. Antenna with 26 segments; frons, vertex and temple coarsely reticulate-punctate (Figs 453, 454, 457); head gradually narrowed behind eyes, eye in dorsal view 0.8 times as long as temple (Fig. 454); occipital carina weakly developed medially, narrowly lamelliform laterally; supra-antennal elevations medium-sized (about 0.1 times as long as scapus), outer side oblique and rugulose; clypeus slightly concave and thick medio-ventrally.
Mesosoma. Length of mesosoma 1.2 times its height (Fig. 459); mesopleuron coarsely reticulate-rugose; transverse mesopleural groove narrow, shallow and weakly crenulate; notauli moderately narrow, deep and coarsely crenulate; middle lobe of mesoscutum coarsely reticulate-punctate, lateral lobes somewhat longitudinally rugose (Fig. 458); scutellar sulcus complete, medium-sized and crenulate medially and wider laterally; scutellum densely and coarsely reticulate-punctate, convex anteriorly and near level of mesoscutum; metanotum medially slightly convex, not protruding and rugose (Fig. 458); propodeum obliquely striate antero-laterally, irregularly rugose medially and posteriorly (Fig. 458); posterior propodeal carina thick lamelliform and slightly arched, foramen medially 0.6 times higher than wide basally.
Wings. Fore wing: length of vein 1-M 1.2 times as long as vein 1-SR (Fig. 456).
Metasoma. First tergite 0.4 times as long as apically wide, smooth and with shallow elliptical depression medially (Fig. 460); second–sixth tergites densely and coarsely reticulate-punctate (Fig. 460); sternites densely and coarsely punctate; second sternite distinctly convex, medio-apical protuberance truncate, not protruding behind apical margin of sternite and posteriorly concave (Fig. 462); third sternite about 0.1 times as long as second sternite and subtruncate apically in lateral view (Fig. 461); hypopygium triangular in ventral view.
Colour. Head largely dark brown with following orange-brown markings: stripes along inner and outer orbita (including malar space), lateral area of clypeus and area above clypeus, V-shaped patch behind stemmaticum; mesosoma largely dark brown to black with following yellowish brown makings: antero-lateral stripes on middle lobe of mesoscutum, tegulae, posterior half of axillae, submedial spot on scutellum, submedian and lateral spots on metanotum, antero-dorsal spot on lateral pronotum side, dorsal spot on mesopleuron, rather large lateral spots on propodeum; metasoma largely black with following orange-brown or yellowish brown markings: narrow stripe on posterior margin of first tergite and sternite, broad stripe on posterior margin of second and third tergites, posterior 0.7 of fourth and almost entirely fifth and sixth tergites, postero-lateral spots on second sternite; mandible dark brown; palpi dark brown; basal half of antenna (including scapus) yellowish brown, otherwise dark brown; legs dark brown to nearly black; pterostigma and anterior half of fore wing dark brown, remainder of wing membrane subhyaline.
Variation. Length of body 7.8–12.7 mm, of fore wing 6.4–10.3 mm; antenna of + with 24–27 segments; orange-brown markings on body paler or darker; length of vein 1-M of fore wing 1.0–1.2 times as long as vein 1-SR.
