Redescription. Female.

Body length: 5.20-5.37 mm (N = 2).

Color. Head yellow with upper frons and vertex dark brown to black; mesosoma variably yellow to dark brown; mandible yellow with teeth dark brown; palpi yellow; legs yellow throughout; A1-A5 brown, remainder of antenna dark brown to black; fore wing hyaline.

Head. Transverse in dorsal view, 1.5-1.65 × as wide as long, as wide as mesosoma; OOL short, 0.20-0.30 × times minimum diameter of lateral ocellus; POL 1.38-1.4 × LOL; occipital carina interrupted medially; central keel weakly developed, extending onto interantennal process; medial frons punctate rugose ventrally, with irregularly shaped smooth area dorsally; frons below median ocellus densely punctate; posterior vertex rugulose behind posterior ocelli, becoming punctate reticulate posteriorly; gena punctate rugose; length of A3 1.1-1.2 × length of A2.

Mesosoma. Cervical pronotal area densely punctate; dorsal pronotal area punctate rugulose; lateral pronotal area smooth dorsally, punctate rugulose ventrally; netrion densely finely punctate; notaulus shallow, foveolate; middle lobe of mesoscutum densely punctate, sculpture becoming denser anteriorly and posteriorly; lateral lobes of mesoscutum densely finely punctate throughout; mesoscutellum densely finely punctate throughout; metascutellum transverse, posterior margin slightly pointed medially, longitudinally carinate; propodeum continuous medially, not divided into two separated lobes, posterior margin narrowly notched medially, each side with several irregular longitudinal carinae medially, otherwise punctate rugose, 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; metapleuron punctate rugose throughout.

Legs. Slender; hind femur weakly swollen, 3.60-3.80 × as long as its maximum width; hind tibia without spines over outer surface; hind basitarsus 9.60-10.20 × as long as its maximum width.

Wings. Apex of fore wing extending from as far as middle of T5; R 1.56-1.67 × as long as r-rs, R1 1.63-1.70 × length of R.

Metasoma. Posterior margin of transverse sulcus on T2 strongly convex; sublateral tergal carinae well developed on T1-T2, weakly developed on anterior half of T3; T1 densely longitudinally striate, with punctate rugulose sculpture in interstices anteriorly, punctate rugulose laterally; T2-T4 densely longitudinally striate with numerous large delicate punctures in interstices; T5-T6 densely punctate; length of T3 1.35-1.40 × length of T6; T5 distinctly wider than long; S2-S4 densely longitudinally striate, with delicate punctures in interstices; S5-S6 densely finely punctate; prominent longitudinal median carina absent on sternites.

Male. Differing from female as follows: body length 3.76 mm (N = 1); A1 yellow, the remainder of antenna dark brown to black; mesosoma dark brown to black dorsally, yellow laterally; T1-T4 densely longitudinally striate, with numerous delicate punctures in interstices; T5-T6 densely and finely punctate; T7 largely smooth except finely rugulose posterolaterally; T6 wider than long; length of T6 2.50 × length of T7; T7 transverse, apex truncate; length of T7 as long as S7; S7 granulate.

Distribution.

China (Xinjiang, Hebei, Inner Mongolia); Russia, Hungary.

Comments.

Macroteleia variegata is recorded here from China for the first time. We examined the holotypes of M. variegata and M. ischtvani and found no distinct differences between the two species except the trivial variations in colors and the relative length of metasomal tegites, which Kononova and Kozlov (2008) used heavily in the key to species of the Palearctic Macroteleia . Therefore, we here treat M. ischtvani as a synonym of M. variegata . We also examined a paratype of M. elissa Kozlov & Kononova, 1987 deposited in UASK that we believe is conspecific with M. variegata , but we cannot confirm if M. elissa should be treated as a synonym of M. variegata until we can examine the holoype of M. elissa . Color and size variations could be due to temperature or host egg size during the developmental stage of the parasitoids, which are quite commonly seen in Scelionidae . DNA barcoding could be useful in species delimitation for the species in such situations.
