Description
Female. Body length 5.83–6.36 mm (n=4).
Color. Head yellow with upper frons and vertex dark brown to black; mesosoma variably yellow to dark brown; metasoma black; mandible dark brown; palpi yellow; legs yellow throughout; A1–A6 yellow, A7–A12 black; fore wing subhyaline.
Head. Transverse in dorsal view, 1.42–1.46× as wide as long, slightly wider than mesosoma; lateral ocellus contiguous with inner orbit of compound eye; POL 1.54–1.55× LOL; occipital carina continuous medially, coarsely and densely punctate; central keel well developed, extending onto interantennal process, slightly bifurcating dorsally (Plate 57A); medial frons smooth; ventrolateral frons punctate rugose; frons below median ocellus and vertex punctate reticulate; gena punctate rugose; length of A3 1.16–1.18× length of A2.
Mesosoma. Cervical pronotal area densely punctate; dorsal pronotal area areolate; lateral pronotal area anteriorly with several carinae subparallel to vertical epomial carina, otherwise smooth with sparse punctures; netrion finely punctate; notaulus deep, distinctly foveolate; mesoscutum densely punctate throughout; mesoscutellum sparsely punctate medially, densely punctate laterally; metascutellum semicircular (Plate 57B), extending to gap between propodeal lobes, irregularly areolate rugose; propodeum divided into two widely separated subtriangular lobes (Plate 57B), each side with rugose sculpture covered by dense, recumbent, white setae; upper mesepisternum with a row of robust longitudinal carinae below subalar pit; lower mesepisternum variably smooth to punctate rugulose; mesopleural depression smooth (Plate 57C); metapleuron smooth dorsally, punctate rugose ventrally.
Legs. Robust; hind femur strongly swollen, 2.31–2.46× as long as its maximum width; hind tibia without spines over outer surface; hind basitarsus 3.63–4.23× as long as its maximum width.
Wings. Apex of fore wing extending as far as mid-length of T5; R 1.38–1.60× as long as r-rs, R1 1.81–2.00× length of R.
Metasoma. Posterior margin of transverse sulcus on T2 strongly convex (Plate 57D); sublateral tergal carinae developed on T1–T3; T1 longitudinally punctate rugulose anteriorly, densely striate posteriorly; T2–T4 longitudinally punctate rugulose throughout; T5 –T6 finely punctate rugulose dorsally, densely longitudinally striate laterodorsally, with scattered small punctures in interstices; length of T3 0.63–0.66× length of T6; T5 slightly longer than wide; S2–S6 densely longitudinally striate, with coarse punctures in interstices; prominent longitudinal median carina present on S2–S4.
Male. Differing from female as follows: body length 4.12–5.56 mm (n=8); antenna yellow with A6–A11 brown; mesosoma variably brown to nearly black; fore wing slightly infuscate in basal half; propodeum continuous medially (Plate 58A), not divided into two separated lobes, posterior margin excavate medially, each side with several irregular longitudinal carinae medially, otherwise rugose; T1 sparsely longitudinally striate throughout; T7 largely smooth except finely rugulose posterolaterally; T6 wider than long or slightly longer than wide; length of T6 3.80–4.75× length of T7; T7 transverse, apex truncate (Plate 58B); length of T7 0.67–0.85× length of S7; S7 longitudinally punctate rugulose.
Diagnosis
Macroteleia semicircula shares the well-developed central keel and robust legs with Macroteleia salebrosa and Macroteleia striatipleuron, but can be distinguished by the semicircular metascutellum (rectangular in the latter two species).
Etymology
The name semicircula refers to the semicircular metascutellum of this species and is used as a noun in apposition.
