Description.

Female. Body length 4.35-5.76 mm (n=5).

Color. Head and mesosoma orange yellow; base of T1 and T6 variably dark brown to black, otherwise orange yellow; mandible dark brown; palpi yellow; legs yellow throughout; A1-A6 brown, A7-A12 black; fore wing hyaline.

Head. Transverse in dorsal view, 1.40 –1.44× as wide as long, slightly wider than mesosoma; OOL short, 0.14 –0.31× minimum ocellar width; POL 1.20 –1.31× LOL; occipital carina weakly continuous or interrupted medially; central keel absent (Plate 25C); medial frons punctate rugulose ventrally, irregularly smooth dorsally; ventrolateral frons punctate rugose; frons below median ocellus densely punctate; vertex densely punctate, with punctures in part contiguous; gena punctate rugose; length of A3 equal to length of A2.

Mesosoma. Cervical pronotal area densely punctate; dorsal pronotal area punctate rugose; lateral pronotal area smooth anteriorly, punctate rugulose posteriorly; netrion punctate rugulose; notaulus narrow, but distinctly foveolate; middle lobe of mesoscutum densely punctate, becoming denser anteriorly and at posterior end; lateral lobes of mesoscutum densely punctate throughout; mesoscutellum densely punctate throughout; metascutellum distinctly transverse (Plate 25D), posterior margin slightly pointed medially, longitudinally carinate; propodeum continuous medially (Plate 25D), not divided into two separated lobes, posterior margin narrowly notched medially, each side with several irregular longitudinal carinae medially, otherwise punctate rugulose, covered by dense, recumbent, white setae; upper mesepisternum with a row of fine longitudinal carinae below subalar pit; lower mesepisternum punctate rugulose; mesopleural depression smooth (Plate 25E); metapleuron longitudinally striate throughout.

Legs. Slender; hind femur weakly swollen, 3.60 –4.39× as long as its maximum width; hind tibia without spines over outer surface; hind basitarsus 11.66 –12.83× as long as its maximum width.

Wings. Apex of fore wing extending from as far as posterior third to posterior margin of T4; R 1.76 –2.25× as long as r-rs, R1 1.39 –2.00× length of R.

Metasoma. Posterior margin of transverse sulcus on T2 strongly convex (Plate 25F); sublateral tergal carinae developed on T1-T3; T1 densely longitudinally striate medially, with scattered punctures in interstices anteriorly, rugulose laterally; T2-T3 densely longitudinally striate medially, with delicate punctures in interstices, punctate rugulose laterally; T4-T5 densely finely longitudinally striate throughout, with delicate punctures in interstices; T6 finely punctate dorsally, densely longitudinally striate laterally, with scattered small punctures in interstices; length of T3 0.83 –0.99× length of T6; T5 distinctly longer than wide; S2-S4 longitudinally striate, with finely punctate rugulose interstices; S5-S6 longitudinally striate, with finely punctate interstices; prominent longitudinal median carinae present on S2-S5.

Male. Differing from female as follows: body length 4.55-5.26 mm (n=6); head brown; mesosoma darker than female; metasoma variably brown to black; A1 yellow, remainder of antenna brown to dark brown; T1-T3 densely longitudinally striate medially, with delicate punctures in interstices, rugulose laterally; T4-T7 longitudinally punctate rugulose; T6 slightly longer than wide; length of T6 1.09 –1.27× length of T7; T7 subtriangular, apex pointed (Plate 26B, 26C); length of T7 1.75 –2.29× length of S7; S2-S5 longitudinally striate, with delicate punctures in interstices; S6-S7 longitudinally punctate rugulose.

Diagnosis.

The body shape, color and size of Macroteleia flava is similar to Macroteleia rufa and Macroteleia chandelii . It differs from them in that metascutellum is distinctly transverse (triangular in Macroteleia rufa , tongue-like in Macroteleia chandelii ), and the propodeum is continuous medially, not divided into two separated lobes (divided into two subtriangular lobes in the latter two species).

Etymology.

The name flava refers to orange yellow body color of this species and is used as an adjective.
