Diagnosis.

Face and temple usually with small pale patches, but sometimes entirely absent; mesoscutum very densely to rather sparsely sculptured, as striations of supra-antennal elevations; mesosoma with linear ivory pattern dorsally (at least with large ivory patches on scutellum and metanotum; Figs 182, 190, 202, 213); posterior half of propodeum largely smooth (Figs 182, 190, 202, 213); vein 1m-cu of fore wing connected to first submarginal cell (Figs 195, 200, 211); legs mainly black or dark brown (except pale trochanter and trochantellus); apical half of first tergite with pair of pale spots (♀) or black (♂) (Figs 184, 192, 204, 215, 219); medially third sternite 0.8-1.0 times as long as second sternite (Figs 185, 194, 206, 217), rarely less; fifth and sixth metasomal tergites dark brown or black medio-apically (Figs 181, 192, 202, 215); comparatively slender species (Figs 181, 186, 196, 207).

Description.

Redescribed after a female from Sichuan, length of body 7.4 mm (of fore wing 6.2 mm).

Head. Antenna with 25 segments; frons and vertex sparsely and superficially punctate; temple smooth; head subparallel-sided behind eyes, eye in dorsal view 1.2 times as long as temple (Fig. 209); occipital carina weakly developed and weakly crenulate dorsally (Fig. 209); supra-antennal elevations medium-sized (about 0.4 times as long as scapus), outer side subvertical and largely smooth except for sparse fine punctures (Fig. 209); clypeus slightly concave and thick medio-ventrally.

Mesosoma. Length of mesosoma 1.6 times its height (Fig. 214); mesopleuron below transverse mesopleural groove smooth, above groove mainly smooth with longitudinal foveolae medially; transverse mesopleural groove wide, deep and coarsely crenulate; notauli wide, deep and coarsely crenulate; middle lobe of mesoscutum densely punctate rugose anteriorly, largely smooth with sparse fine punctures posteriorly, lateral lobe densely punctate rugose with a narrow mid-longitudinal furrow (Fig. 213); scutellar sulcus wide, both medially and laterally and coarsely crenulate; scutellum mainly smooth, rather flat and anteriorly near level of scutellum (Fig. 213); metanotum medially slightly convex, not protruding and smooth (Fig. 213); anterior half of propodeum irregularly areolate or rugose, posterior half largely smooth with a longitudinal carina medially (Fig. 213); posterior propodeal carina thick lamelliform and hardly arched, foramen medially 0.3 times higher than wide basally.

Wings. Fore wing: length of vein 1-M 2.5 times as long as vein 1-SR (Fig. 211).

Metasoma. First tergite 0.5 times as long as apically wide, smooth and without shallow depression antero-medially (Fig. 215); other tergites and sternites smooth to superficially coriaceous and shiny (Figs 215, 217); third sternite about 0.6 times as long as second sternite (Fig. 217); hypopygium triangular in ventral view (Fig. 217).

Colour. Black; mandible largely (but teeth dark brown), broad stripes of inner and outer orbita, clypeus largely (except for median dark brown spot), large posterior spot on middle lobe of mesoscutum, broad median longitudinal stripe on scutellum, large median spot on metanotum, stripe on upper pronotum and lower pronotum, oblique stripe on upper mesopleuron and broad patch on lower mesopleuron, small spot on metapleuron, large lateral spots on propodeum, trochanters and trochantelli and outer side of coxae, posterior and lateral margin of all metasomal tergites and sternites, ivory or pale yellow; remainder of metasoma largely dark brown to nearly black; palpi yellowish brown; antenna black with a large ivory band subapically; fore and mid tibiae and all tarsi yellowish brown, remainder of legs dark brown to nearly black; pterostigma dark brown; wing membrane subhyaline.

Variation. Length of body 5.8-8.3 mm, of fore wing 4.7-7.4 mm; upper mesopleuron with large interrupted ivory patch or an oblique stripe or mesosoma laterally entirely (Japan) or largely black; ivory patch of mesoscutum present or absent; ivory patches on posterior and lateral margin of all tergites and sternites comparatively small or large; clypeus entirely ivory or with dark median spot; inner and outer orbita widely ivory but largely black in holotype of Orthogonalos debilis ; hind coxa entirely dark brown or largely ivory dorsally; length of vein 1-M of fore wing 1.9-2.5 times as long as vein 1-SR.

Male. Length of body 7.4 mm, of fore wing 6.0 mm; antenna with 24 segments; ivory stripe along outer orbita reduced or wide (as in holotype of Orthogonalos hirasana ); lateral mesosoma and propodeum entirely black; metasoma largely black, only with postero-lateral margin of first and second tergites and sternites dark brown (but absent in holotype of Orthogonalos hirasana ); ventral half of clypeus ivory; genitalia extruded (Fig. 219).
