Macroteleia livingstoni Saraswat 1982: 348 (original description).

Description.

Female. Body length 3.28-4.08 mm (n=20).

Color. Body black; mandible dark brown; palpi light brown; legs pale brown throughout; A1 pale brown, A2-A6 brown, remainder of antenna black; fore wing hyaline.

Head. Transverse in dorsal view, 1.20 –1.34× as wide as long, slightly wider than mesosoma; lateral ocellus contiguous with inner orbit of compound eye; POL 1.31 –1.45× LOL; occipital carina continuous medially; central keel weakly developed above interantennal process (Plates 43A, 45A); medial frons obliquely strigose ventrally, irregularly smooth dorsally; ventrolateral frons punctate rugose; frons below median ocellus sparsely punctate; ocellar triangle smooth, with scattered punctures; posterior vertex densely punctate; gena punctate reticulate; length of A3 0.83 –1.00× length of A2.

Mesosoma. Cervical pronotal area densely punctate; dorsal pronotal area densely coarsely punctate; lateral pronotal area smooth in upper anterior angle, punctate rugose posteriorly; netrion punctate rugulose; notaulus narrow, but distinctly foveolate; middle lobe of mesoscutum densely punctate anteriorly and at posterior end, usually sparsely punctate on a small area across middle; lateral lobe of mesoscutum densely punctate throughout; mesoscutellum densely punctate throughout; metascutellum transverse (Plates 43B, 45B), posterior margin slightly pointed medially, longitudinally carinate; propodeum continuous medially (Plates 43B, 45B), 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 weak longitudinal carinae or a ledge below subalar pit; lower mesepisternum variably smooth to punctate rugulose; mesopleural depression smooth (Plates 43C, 45C); metapleuron longitudinally striate dorsally, punctate rugulose ventrally.

Legs. Slender; hind femur weakly swollen, 3.86 –4.69× as long as its maximum width; hind tibia without spines over outer surface; hind basitarsus 10.50 –13.00× as long as its maximum width.

Wings. Apex of fore wing extending from as far as posterior fifth to posterior margin of T4; R 1.82 –2.18× as long as r-rs, R1 1.65 –2.18× length of R.

Metasoma. Posterior margin of transverse sulcus on T2 slightly convex (Plates 43D, 45D); sublateral tergal carinae developed on T1-T3; T1-T3 densely longitudinally striate medially, with scattered delicate punctures in interstices, punctate rugulose laterally; T4-T5 densely 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 1.00 –1.13× length of T6; T5 slightly longer than wide; S2-S6 densely longitudinally striate, with delicate punctures in interstices; prominent longitudinal median carina present on S2-S5.

Male. Differing from female as follows: body length 3.29-3.92 mm (n=20); A1 pale brown, remainder of antenna dark brown, becoming darker apically; T5-T6 moderately longitudinally striate, with delicate punctures in interstices; T7 punctate rugulose throughout; T6 distinctly longer than wide; length of T6 1.00 –1.19× length of T7; T7 subtriangular, apex pointed (Plate 46B); length of T7 1.56 –2.40× length of S7; S6-S7 longitudinally punctate rugulose; prominent longitudinal median carina present on S2-S6.

Diagnosis.

Macroteleia livingstoni is similar to Macroteleia emarginata in body shape and color, but can be distinguished by its smller size and reticulate gena. The male of Macroteleia livingstoni is also similar to that of Macroteleia lamba , but can be distinguished by the fact that the frons below the median ocellus is sparsely punctate with the interspaces smooth (densely punctate, interspaces coriaceous in Macroteleia lamba ); ocellar triangle smooth, with scattered punctures (coriaceous, with scattered punctures in Macroteleia lamba ).
