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.
