Description

Male. Body length 1.9 mm; forewings reaching far beyond apex of metasoma; antenna 0.8 times as long as body.

Head: brown; in dorsal view 1.05 times as wide as long, as wide as mesosoma. Temples behind eyes gradually receding posteriorly. Tentorial pit tiny. Malar sulcus absent. Clypeus weakly convex, oval, 1.85 times as wide as high. Mandible brown, elongate, with upper tooth shorter than lower tooth. Palpi yellow. Eye oval, with few scattered long setae; 0.4 times as high as head and 1.7 times as high as malar space. Frons above base of toruli smooth. Postgenal cushion scanty (Fig. 7 A, B). Antennae: brown. A1 slightly curved, smooth; its apical rim with small lamellae. A2 not compressed. A13 1.4 times as long as A12. Antennomeres length to width ratios in lateral view as in Fig. 7 A, C. Mesosoma: brown, 1.1 times as wide as high. Neck with few scattered setae and shallow longitudinal grooves. Pronotum with median area scarcely setose and pronotal corner densely pubescent, pronotal cushion dense; pronotal corner weakly prominent, rounded; lateral area of pronotum smooth, bare medially. Tegula brown, large. Mesoscutum convex, 1.25 times as wide as long. Humeral sulcus distinct and narrow. Scutellum slightly convex. Anterior scutellar pits large, circular, smooth inside, with narrow septum. Axillar depression finely pubescent and smooth. Lateral scutellar pit broad. Posterior scutellar pits small. Mesopleuron shining bare and smooth, with small depression next to epicnemial pit, subalar ridge below tegula and longitudinal wrinkles postero-ventrally above middle coxa. Epicnemial pit tiny, without pubescence inside. Sternaulus absent. Ventral side of mesopleuron scarcely pubescent. Metanotum pubescent, finely sculptured, with three weakly-projecting keels on metascutellum. Propodeum entirely pubescent and finally sculptured. Median propodeal keel in lateral view high raised anteriorly (Fig. 7 A). All legs slender, pale brown with separated trochantelli. Wings: Stigmal vein as long as width of marginal vein. Costal, basal and cubital veins sclerotised and weakly pigmented. Metasoma: Petiole entirely pubescent. T2 4.5 times as long as petiole, mainly bare and smooth, with small bunch of setae laterally at anterior margin. T3-T5 sparsely pubescent with semi-erect long setae, smooth. T6 small, setose and bare. T7 tapered, setose. S3-S7 with scattered setae, smooth.

Female. Body length 1.7-1.8 mm. Pleurostomal distance 0.74 times as long as shortest distance between eyes (Fig. 8 C). Malar distance 0.73 times as long as largest diameter of eye (Fig. 8 C). Аntennae brown, clavate with abrupt 5-segmented clava, A13 without ventral pit, A4-A8 moniliform and transverse, A10-A13 with distinct MGS brush ventrally (Fig. 8 D). Petiole as long as wide. T2-T6 smooth. T7-T8 weakly punctured. S3-S5 smooth. S6 smooth and densely setose.

Diagnosis

Male. Face without malar sulcus, pleurostomal distance 0.9 times as wide as shortest distance between eyes (Fig. 4 C). Malar distance 0.42 times as long as largest diameter of eye. Front smooth. Аntennae brown, filiform, with A5 1.3 and A12 1.6 times as long as wide in dorsal view. A4 1.1 times as long as A3 and with keel and emargination reaching to half of the segment (Fig. 7 C). Notauli marked as short grooves posteriorly (Fig. 7 B). Scutellum convex, as long as wide (measured without anterior scutellar pits) (Fig. 7 B). Propodeum with weak emargination between plicae. Marginal vein 1.25 times as long as wide. Petiole slightly elongate, about 1.1 times as long as wide. T2 pubescent at the base. S8 setose and densely micropunctate.

Etymology

The name of this species is a composite Latin masculine adjective derived from the adverb “flave” (yellowly) and “corpus” and refers to the colouration of the body.

Distribution

Germany. Further BIN records are online available for Canada. Probably further distributed around the Palaearctic and Nearctic.

Notes

The reason for the selection of the holotype is analogous to that of S. brevimalaris sp. nov. (check Notes).
