Description.

Female. Body length 6.50 mm.

Color. Body black; mandible dark brown; palpi yellow; legs yellow with hind tarsi brown; A1 yellow, A2-A4 brown, A5 dark brown, remainder of antenna black; fore wing subhyaline with medial longitudinal infuscate streak in basal half.

Head. Transverse in dorsal view, width 1.46 × length, as wide as mesosoma; OOL short, 0.25 × minimum ocellar width; POL 1.73 × LOL; occipital carina continuous medially, coarsely and densely punctate; central keel well developed, extending onto interantennal process, slightly bifurcating dorsally (Plate 2A); medial frons smooth dorsally, obliquely strigose ventrally; remainder of frons and vertex punctate reticulate; gena punctate rugose; length of A3 1.03 × length of A2.

Mesosoma. Cervical pronotal area punctate reticulate; dorsal pronotal area areolate; lateral pronotal area anteriorly with several carinae subparallel to vertical epomial carina, otherwise smooth with sparse punctures; netrion finely punctate rugulose; notaulus deep, distinctly foveolate; middle lobe of mesoscutum densely punctate, becoming punctate reticulate anteriorly and posteriorly; lateral lobes of mesoscutum densely punctate throughout; mesoscutellum densely punctate throughout; metascutellum rectangular (Plate 63A), posterior margin convex, extending to gap between propodeal lobes, irregularly areolate rugose; propodeum medially divided into two widely separated subtriangular lobes (Plate 63B), 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 densely punctate; mesopleural depression longitudinally striate (Plate 63B); metapleuron punctate rugose throughout.

Legs. Robust; hind femur strongly swollen, 2.70 × as long as its maximum width; hind tibia without spines over outer surface; hind basitarsus 3.75 × as long as its maximum width.

Wings. Apex of fore wing extending as far as mid-length of T6; R 1.36 × as long as r-rs, R1 1.89 × length of R.

Metasoma. Posterior margin of transverse sulcus on T2 slightly convex (Plate 63C); sublateral tergal carinae developed on T1-T2; T1 longitudinally punctate rugose anteriorly, densely striate posteriorly; T2-T5 longitudinally punctate rugulose throughout; T6 longitudinally striate throughout, with scattered small punctures in interstices; length of T3 0.81 × length of T6; T5 slightly wider than long; S2-S6 densely longitudinally striate, with coarse punctures in interstices; prominent longitudinal median carina strongly developed on S2-S4.

Male. Unknown.

Diagnosis.

Macroteleia striatipleuron shares the well-developed central keel,rectangular metascutellum and robust legs with Macroteleia salebrosa , but can be distinguished by the medially continuous occipital carina (interrupted medially in Macroteleia salebrosa ); longitudinally striate mesopleural depression (smooth in Macroteleia salebrosa ); and yellow hind coxa (dark brown to nearly black in Macroteleia salebrosa ).

Etymology.

The name striatipleuron refers to the longitudinal striae on mesopleural depression of this species and is used as a noun in apposition.
