Description
Male. Body length 4.76–6.05 mm (n=4).
Color. Body black; mandible reddish brown; palpi yellow; hind coxa blackish, tarsi yellow, remainder of legs pale brown; A1 brown, remainder of antenna dark brown; fore wing hyaline.
Head. Transverse in dorsal view, 1.44–1.48× as wide as long, slightly wider than mesosoma; OOL short, 0.17–0.29× minimum ocellar width; POL 1.54–1.57× LOL; occipital carina weakly continuous medially, irregular punctate; central keel weakly developed, extending onto interantennal process (Plate 28A); medial frons punctate rugulose ventrally, with irregularly shaped smooth area dorsally; frons below median ocellus sparsely punctate medially, densely punctate laterally; vertex punctate rugulose; gena punctate rugose; length of A3 1.25–1.31× length of A2.
Mesosoma. Cervical pronotal area densely punctate; dorsal pronotal area punctate rugulose; lateral pronotal area smooth dorsally, punctate rugulose ventrally; netrion finely punctate rugulose; notaulus shallow, foveolate; middle lobe of mesoscutum densely punctate, sculpture becoming denser anteriorly; lateral lobes of mesoscutum densely finely punctate throughout; mesoscutellum densely finely punctate throughout; metascutellum transverse (Plate 28B), posterior margin slightly pointed medially, longitudinally carinate; propodeum continuous medially (Plate 28B), 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 somewhat robust longitudinal carinae below subalar pit; lower mesepisternum variably smooth to punctate rugulose; mesopleural depression smooth (Plate 28C); metapleuron longitudinally striate throughout.
Legs. Slender; hind femur weakly swollen, 4.23–4.80× as long as its maximum width; hind tibia without spines over outer surface; hind basitarsus 12.60–14.00× as long as its maximum width.
Wings. Apex of fore wing extending from as far as posterior fourth of T3 to base of T4; R 2.06–2.46× as long as r-rs, R1 1.63–1.90× length of R.
Metasoma. Posterior margin of transverse sulcus on T2 slightly convex (Plate 28D); sublateral tergal carinae developed on T1–T3; T1–T2 sparsely and longitudinally striate medially, with delicate punctures in interstices, punctate rugulose laterally; T3–T6 densely longitudinally striate, with numerous delicate punctures in interstices; T7 punctate rugulose throughout, with longitudinal tendency; T6 distinctly longer than wide; length of T6 0.93–1.18× length of T7; T7 subtriangular, apex pointed (Plate 28E, 28F); length of T7 2.50–3.22× length of S7; S2–S3 sparsely longitudinally striate, with numerous delicate punctures and irregular microsculptures in interstices; S4–S7 densely longitudinally striate, with numerous delicate punctures in interstices; prominent longitudinal median carina present on S2–S5.
Female. Unknown.
Diagnosis
The male of this species is similar to that of Macroteleia emarginata in size and color, but can be distinguished in having the metapleuron longitudinally striate throughout (Macroteleia emarginata longitudinally striate dorsally, punctate rugulose ventrally); and the length of T7 2.50–3.22× length of S7 (distinctly shorter, 1.42–1.87× in Macroteleia emarginata).
Etymology
The name gracilis refers to the slender body of this species and is used as an adjective.
