Diagnosis
This species is distinguished from other species in the genus by the following characters: face and mesopleuron matt or weakly shining, shagreened, and at most weakly punctate; face and clypeus weakly projecting centrally; hind tibia basally reddish (Fig. 6D); metasoma black; first metasomal tergite convex in profile; metasomal tergites 1–3 strongly punctate with strong transverse impressions; parameres relatively thin.
Etymology
This species is named after Reijo Jussila.

Description
Female
Fore wing around 6–7 mm long. Antenna slender, about as long as fore wing, with 30–32 flagellomeres. Ratio of length of 1 st plus 2 nd flagellomeres to eye height 1.0. Scape 1.6 times as long as broad. Head not narrowed behind eyes, matt, with scarce, fine punctures on shagreened surface. Lateral ocellus separated from eye margin by 1.6 times their widest diameter. Face transverse 2 times as wide as high, with scattered fine punctures (Fig. 6A). Clypeus 0.4 times as high as wide, distinctly separated from face by a deep impression, projecting medially, weakly shining and sparsely punctate, its apical margin thin and laterally impressed. Clypeal fovea shallow. Malar space 0.75 times of basal mandible width. Occipital carina complete. Mandible teeth of equal length.
Mesoscutum weakly shining, not granulate and with scattered but uniformly strong punctation. Notaulus distinct. Mesopleuron finely granulate, striated in upper part, shining, distinctly densely and strongly punctate (Fig. 6B). Metapleuron weakly shining, rugose, with rather dense but vague punctation in upper part. Propodeum strongly rugose (Fig. 6C). Area superomedia fused with area basalis, their combined area 2.6 times as long as broad. Costula absent. Area apicalis trapezoidal, 0.6 times as long as broad, and equal to 0.5 of propodeum, often with longitudinal carina and sometimes with striation. Spiracles weakly oval, 1.56 times as long as broad. Hind femur 5 times as long as broad. Hind tibia 7.9 times as long as apically broad. First tarsomere of hind leg 6.7 times as long as broad and 2.1 times as long as second tarsomere. Claws not pectinate. Fore wing with pterostigma elongate, around 3 times as long as broad and intercepted by Rs before its middle. 2m-cu straight, with a single bulla. Cu-a vertical, slightly postfurcal. Hind wing with 1/Cu & cu-a intercepted by 2/Cu in lower 0.5.
Metasoma reticulate rugose and strongly punctate. First metasomal tergite as long as apically broad (Fig. 6C) and projecting dorsally, its dorsal longitudinal carinae reaching middle of tergite, with a strong impression between carinae in basal part. Area between dorsal carina and spiracle with impression. Spiracles projecting laterally. Subapical transverse impression strong and slightly wider laterally than medially. First metasomal sternite 0.3 times as long as its tergite. Second metasomal tergite 0.5 times as long as apically broad, its transverse impression starting immediately after middle of tergite. Third tergite with weak transverse impression. Ovipositor sheaths weakly clavate and 0.6 times as long as height of last visible tergite. Ovipositor stout at base with a triangular shape before shallow subapical notch, its lower valvae slightly swollen before thin tip and tip of upper valve after notch 0.28 times as long as ovipositor length (Fig. 5G).
Colouration: body mostly black (Fig. 6); antennal flagellomeres and pterostigma brownish; clypeus, legs (except coxa and tibia and tarsus of hind legs), second and third metasomal sternites reddish.
Male
Morphologically similar to female, but with clypeus shorter (0.3 times as long as broad) and upper tooth of mandible slightly longer than lower. Parameres broad basally and weakly elongate apically, extending beyond aedeagus, volsella moderately large with apical notch, aedeagus apically downcurved.
Colouration as in female, but middle tergites sometimes with red spots. Face, clypeus, malar space, mandibles (except teeth), upper part of scape, flagellum ventrally, fore and middle coxae and trochanters, lower part of propleuron, epicnemius, hind angle of pronotum, tegulae and sternites yellow.
