description
Description HEAD. Head shape kite-like or rhomboid; frontal projection rectangular or triangular in frontal view; frons granulate or smooth, usually with low ridge extending from vertex along inner eye margin; frons usually without carinae and wrinkles towards median ocellus, usually without frontal line; spraclypeal area usually with transverse carinae; apical margin of mandible acute (female) or rounded (male); temple shorter or longer than MOD; POL longer or as long as MOD; OOL longer than MOD; LOL usually shorter than half of MOD; behind ocelli with or without transverse depression; cervical expansion trapezoid or cuboid in dorsal view and convex or flattened in lateral view; scape usually with longitudinal grooves; scape 2 – 4.5 times as long as wide, usually with a flange on ventral surface; F 2 – 10 1.5 – 3.0 times as long as wide, F 11 about as long as F 2 (males); F 2 – 10 as wide as or wider than long (females); F 11 flattened (females) or cylindrical (males). MESOSOMA. Mesosoma polished; anterior margin of pronotum usually linear, sometimes depressed; dorsolateral surface of pronotum carinate or rounded; notauli conversing posteriorly or parallel, usually reaching posterior margin; tegula very large, covering both wing bases and extending back to posterior margin of scutellum; scutellum punctured and rugose or smooth, usually with lateral carinae; metanotum with or without medial ridge; mesopleuron usually with scrobal sulcus, strongly or weakly depressed; propodeum usually slightly rounded in lateral view, with propodeal angle, usually without transverse carina above foramen; upper area of propodeum usually without transverse carina. LEGS. Legs usually polished; femora with flanges; tibiae with or without flanges; dorsolateral surface of tibiae usually with longitudinal carinae; dorsolateral surface of hindcoxa usually with longitudinal carinae, rarely absent; shape of hind femur variable, basally stout, apparently wider than distal part (Fig. 2 A), or moderately stout, as wide as distal part (Fig. 2 B), or simple and not stout, as wide as distal part (Fig. 2 C – D); outer margin of hindfemur usually flat (Fig. 2 A – B, D), rarely swollen in median part (Fig. 2 C); ventral margin of hindfemur usually flat (Fig. 2 A – B), sometimes swollen (Fig. 2 C – D); tarsal claw of hindleg usually with a median tooth (Fig. 25 A – H, J – K, M – Q), rarely without tooth (Fig. 25 I, L); median tooth usually not extending half of tarsal claw (Fig. 25 A, C – H, M – O, Q). WINGS. Forewing membrane usually maculate, with A, Cu + M, M, R 1, R, cu-a, and Rs vein (Fig. 3 A – B); forewing venation developed to half of forewing (Fig. 3 A); A usually half as long as Cu + M (Figs 4 G, 10 E), sometimes as long as Cu + M; M usually curved (Fig. 3 A), rarely straight or M vein absent (e. g., L. fulgens Kimsey, 2012, L. reducta Maa & Yoshimoto, 1961); R 1 usually 0.3 – 1.0 times as long as R, rarely absent; cu-a usually 0.4 – 1.0 times as long as R (Figs 5 G, 7 F), sometimes absent (Figs 12 E, 17 G, 21 F); Rs usually more than 2.5 times as long as R. METASOMA. Metasoma polished; five visible segments in males. Females similar to male, four segments visible. PILOSITY. Eye usually without setae, rarely with sparse erect simple or scale-like setae; frontal projection usually with dense erect simple setae, sometimes with cuneate or scale-like setae; clypeus usually with sparse erect simple setae; lower gena with sparse suberect simple or cuneate setae; gena with ribbon-like setae; temple usually with sparse simple setae, sometimes with cuneate setae; cervical expansion with sparse simple setae and ribbon-like setae; antenna with sparse simple or cuneate setae; anterolateral margin of pronotum with ribbon-like setae, longer than those on gena; dorsal surface of pronotum usually with sparse simple or suberect cuneate setae, rarely with forked setae; propleuron sometimes with cuneate setae; scutum with sparse simple or suberect cuneate setae; tegula usually with sparse simple or cuneate setae, rarely with forked setae; mesopleuron usually with sparse cuneate setae; metanotum rarely with forked setae; propodeum with sparse simple setae or suberect cuneate setae in lateral view; apical half of coxae with sparse suberect simple or cuneate setae; femora usually with sparse simple and cuneate setae; tibiae with dense simple or cuneate setae.
diagnosis
Diagnosis Frontal projection rectangular or triangular in frontal view; behind ocelli with or without transverse depression; cervical expansion trapezoid or cuboid in dorsal view, convex or flattened in lateral view; ribbon-like setae extending from adjacent to eye to apex of cervical extension of head; scape 2 – 4.5 times as long as wide, usually with flange on ventral margin; F 11 about as long as F 2 (males); F 2 – 10 as wide as or wider than long (females); F 11 flattened (females) or cylindrical (males); lateral margin of pronotum parallel or more commonly diverging posteriorly in dorsal view; dorsolateral surface of pronotum carinate or rounded; mesopleuron usually with scrobal sulcus; scutum usually with notauli; notauli usually reaching posterior margin; scutellum trapezoid or subtriangular; forewing A vein present, usually cu-a vein present, venation extending 0.3 – 0.5 times as long as forewing length; femora and tibiae usually with transparent flange; dorsolateral surface of hindcoxa usually with carinae.
