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; F11 about as long as F2 (males); F2–10 as wide as or wider than long (females); F11 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.
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; F2–10 1.5–3.0 times as long as wide, F11 about as long as F2 (males); F2–10 as wide as or wider than long (females); F11 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. 2A), or moderately stout, as wide as distal part (Fig. 2B), or simple and not stout, as wide as distal part (Fig. 2C–D); outer margin of hindfemur usually flat (Fig. 2A–B, D), rarely swollen in median part (Fig. 2C); ventral margin of hindfemur usually flat (Fig. 2A–B), sometimes swollen (Fig. 2C–D); tarsal claw of hindleg usually with a median tooth (Fig. 25A–H, J–K, M–Q), rarely without tooth (Fig. 25I, L); median tooth usually not extending half of tarsal claw (Fig. 25A, C–H, M–O, Q).
WINGS. Forewing membrane usually maculate, with A, Cu+M, M, R1, R, cu-a, and Rs vein (Fig. 3A–B); forewing venation developed to half of forewing (Fig. 3A); A usually half as long as Cu+M (Figs 4G, 10E), sometimes as long as Cu+M; M usually curved (Fig. 3A), rarely straight or M vein absent (e.g., L. fulgens Kimsey, 2012, L. reducta Maa & Yoshimoto, 1961); R1 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 5G, 7F), sometimes absent (Figs 12E, 17G, 21F); 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.
