Molecular data.

MRS294 (Sweden), MRS312 (Sweden), MRS314 (Sweden), MRS673 (Finland), MRS674 (Finland), MRS676 (Finland), MRS680 (Finland).

Biology.

Unknown. Collected from July-August; presumably univoltine. We have not seen reared material and there is no indication of how the winter may be passed.

Diagnosis.

Maximum width of hypoclypeal depression approx. 0.4 × minimum width of face (Fig. 695 ); OOL of ♀ 1.1-1.5 × as long as diameter of posterior ocellus and punctate-rugulose to coriaceous-rugose (Fig. 696 ); length of antenna of ♀ 1.0-1.1 × length of fore wing; ventral margin of clypeus thin and not protruding in lateral view (Fig. 697 ); mesoscutal lobes remotely punctulate and with satin sheen; area of precoxal sulcus smooth; length of vein 1-CU1 of fore wing 0.2-0.3 × vein 2-CU1 and 0.4 × vein m-cu; vein 2-SC+R of hind wing subquadrate; tarsal claws with robust apical tooth and with medium-sized yellowish brown pecten (Fig. 698 ); hind femur and basitarsus slender (Fig. 686 ); 1st metasomal tergite comparatively steep anteriorly (Fig. 686 ); head (largely) black; apex of hind femur usually largely black dorsally; basal half of hind tibia (largely) pale yellowish; 2nd tergite yellowish or reddish; males usually with dense and long setosity on at least basal half of 4th-6th tergites.

Description.

Redescribed ♀ (RMNH) from Finland ( Enntekiö). Length of fore wing 5.3 mm, of body 5.8 mm.

Head. Antennal segments of ♀ 51, antenna as long as fore wing, its subapical segments rather robust and apical segment with short spine (Fig. 700 ); frons largely smooth, except for some micro-sculpture; OOL 1.2 × diameter of posterior ocellus, coriaceous-rugose and slightly shiny, groove beside posterior ocellus rather shallow and crenulate; vertex coriaceous with some rugulae, rather dull; clypeus rugose; ventral margin of clypeus thin and not protruding forwards (Fig. 697 ); width of hypoclypeal depression 0.4 × minimum width of face (Fig. 695 ); length of eye 1.7 × temple in dorsal view (Fig. 696 ); vertex behind stemmaticum coriaceous-rugulose; clypeus near lower level of eyes; length of malar space 0.4 × length of eye in lateral view.

Mesosoma. Mesoscutal lobes largely punctate-coriaceous, with satin sheen; precoxal area of mesopleuron partly remotely punctate as its surroundings; medio-longitudinal carina of metanotum distinct posteriorly; scutellum punctate; propodeum convex and coarsely rugose, medio-longitudinal carina absent posteriorly, and without protruding carinae laterally.

Wings. Fore wing: r 0.3 × 3-SR (Fig. 688 ); 1-CU1 slightly oblique, 0.3 × 2-CU1; r-m 0.5 × 3-SR; 2nd submarginal cell long (Fig. 688 ); cu-a slightly inclivous, straight but posteriorly slightly curved; 1-M nearly straight posteriorly; 1-SR wide; surroundings of M+CU1, 1-M and 1-CU1 densely setose. Hind wing: marginal cell linearly widened, its apical width 1.7 × width at level of hamuli (Fig. 689 ); 2-SC+R subquadrate; m-cu absent; M+CU:1-M = 26:25; 1r-m 0.6 × 1-M.

Legs. Tarsal claws with rather conspicuous and medium-sized brownish pecten (Fig. 698 ); hind coxa densely punctate; hind trochantellus rather robust; length of hind femur and basitarsus 4.8 and 6.4 × their width, respectively; length of inner hind spur 0.5 × hind basitarsus.

Metasoma. First tergite convex and basally rather steep, 0.9 × longer than wide apically; 1st and 2nd tergites with medio-longitudinal carina and longitudinally rugose; maximum width of 2nd tergite 1.6 × its median length; medio-basal area of 2nd tergite medium-sized triangular and rather short (Fig. 692 ); 2nd suture deep and finely crenulate; basal half of 3rd tergite rugulose, remainder of metasoma superficially micro-sculptured; 4th and apical half of 3rd tergite without sharp lateral crease; ovipositor sheath wide, with long setae and apically truncate (Fig. 687 ).

Colour. Black; mesoscutum largely, legs, and 1st-3rd metasomal tergites (but 3rd tergite narrowly infuscate posteriorly) reddish brown; tegulae brownish yellow; ovipositor sheath, palpi, pterostigma and veins dark brown; telotarsi partly infuscate; wing membrane subhyaline.

Variation. Legs usually largely reddish, but telotarsi, apices of hind femur and tibia frequently dark brown and sometimes most of hind tibia and apical half of hind femur black; clypeus blunt to rather acute ventrally; depression near posterior ocelli smooth or finely crenulate; mesoscutum of ♀ usually partly reddish brown, but sometimes largely or entirely black; ventral third of mesopleuron regularly and finely punctate. Antennal segments: ♀ 57(2), 59(1); ♂ 57(1), 59(1), 60(5), 61(1), 62(1). Male is very similar with mesoscutum black (rarely partly reddish) and at least 2nd tergite orange brown (sometimes with pair of dark brown patches), apical tergites type 1-2 with fringe rather strong when visible, and also often evident on tergites following the third.

Distribution.

Finland, Norway, Sweden.
