Eridolius kambaiti Kasparyan, 1998  . Entomological Review , 78(3): 273–279. Myanmar ( NHRS). Examined. 

Type material examined. Holotype, female, “N.E. BURMA, Kambaiti , 2000 m, 28.5.1934, Malaise”, ( NHRS). 

Diagnosis. This species can be distinguished from all other Oriental species of the genus by the following characters: lower mandibular tooth just slightly longer than upper one ( Fig. 27View FIGURES26–29), T1 without flanges at glymmas, fore and middle coxae and all trochanters yellow, hind legs reddish except hind tibia, tarsus and apical part of femur brown ( Figs 26–29View FIGURES26–29), metasoma black with yellow posterior margins of T2–T7 ( Fig. 29View FIGURES26–29). This species is similar to the Palaearctic species E. ussuriensis Kasparyan, 1990  , but differs by much slender hind femur (6.2 × as long as broad) and T1 (2 × as long as broad apically).

Description. Holotype female. Length of body 6.0 mm. Length of fore wing 5.7 mm.

Head. Flagellum broken, its two basal flagellomeres 1.34 × as long as maximum diameter of eye; first flagellomere 5.7 × as long as wide at apex. Head roundly narrowed posteriorly ( Fig. 26View FIGURES26–29); length of gena in middle 1.1 × transverse eye diameter; cheek convex below eye; gena smooth. Face widened ventrally with a weak median bulge ( Fig. 27View FIGURES26–29), smooth and polished. Frons smooth. Clypeus distinctly separated from face by depression, smooth, without punctures; its lower margin obtuse with a comb of setae. Malar space 0.5 × as long as basal width of mandible. Upper mandibular tooth slightly shorter than lower one; mandible not swollen before base, smooth, without punctures, with defined transverse depression at base ( Fig. 27View FIGURES26–29). Hypostomal carina not raised behind mandibles.

Mesosoma. Mesoscutum with fine and moderately dense punctures ( Fig. 29View FIGURES26–29). Mesopleuron (except for speculum) with uniform fine and moderately dense punctures; speculum large, covering about 0.75 × length of mesopleuron, polished part below mesopleural pit expands to posterior corner of mesopleuron. Scutellum rather finely punctate ( Fig. 26View FIGURES26–29). Metapleuron smooth without punctures. Propodeum shining, rather pubescent with long, dense white setae, with distinct punctures; basal area 0.5 as long as broad; costulae distinct; areola hexagonal, apical area 0.64 × as long as basal area and areola combined, with median longitudinal carina ( Fig. 28View FIGURES26–29). Pterostigma nearly 5 × as long as wide ( Fig. 29View FIGURES26–29). Areolet petiolate ( Fig. 29View FIGURES26–29). Fore wing with cu-a slightly postfurcal. Hind wing with cu-a intercepted below the middle. Fore claws with 4 teeth. Hind femur 6.2 × as long as wide; proportion of the length of hind tarsomeres 1 to 5: 5.3: 2.7: 1.8: 1: 2.

Metasoma. T1 1.6 × as long as apically broad with median dorsal carinae extending to 0.65 its length, the space between carinae smooth and impunctate; dorso-lateral carinae defined, up to apical 0.6. T1 (beyond spiracles) and T2 completely smooth and more or less evenly covered with distinct punctures, average distances between punctures equal to 1–2 × their diameter. Last sternite elongate. Parameres broad basally.

Color. Body mostly black ( Figs 26–29View FIGURES26–29). Antenna dark brown, first and second flagellomeres ventrally reddishbrown. Clypeus except its narrow basal part, mandibles except teeth, palps ( Fig. 27View FIGURES26–29), posterior edges of pronotum, tegulae ( Fig. 26View FIGURES26–29), fore and middle coxae and all trochanters yellow ( Fig. 29View FIGURES26–29). Legs reddish except: hind tibia and tarsus brown, fore and middle tibiae basally reddish-brown, hind femur dark apically. Metasoma black, T2–T7 with whitish posterior margin ( Fig. 29View FIGURES26–29). Sternites white with pair of black marks. Hypopygium black with white posterior margin. Pterostigma brown.

Male. Unknown.

Distribution: Myanmar (kachin).
