Diagnosis

Like members of the Palaearctic hyalinatus species group (see Astafurova & Proshchalykin 2017a) the new species has a pronotum rounded between the dorsal and lateral surfaces, but it clearly differs by the presence of a sharp carina between the lateral and vertical surfaces of the propodeum ( Fig. 7D View Fig ). From S. engeli Astafurova & Proshchalykin, 2020 , another Oriental species of this group, the new species differs by the shape of the head with а rounded vertex as seen in frontal view (vs the head with a straight upper margin in S. engeli ).

Etymology

This species is dedicated to famous German entomologist Paul Blüthgen (1880–1967), in recognition of his significant contributions to the study of bees and wasps.

Description

Female ( Fig. 6 View Fig , holotype)

MEASUREMENTS. Total body length 7.0– 7.5 mm; forewing length (without tegula) 5.8–6.0 mm.

HEAD. Black ( Fig. 7A View Fig ); transverse, ca 1.25 times as wide as long; preoccipital carina absent; vertex weakly elevated, distance from top of head to upper margin of a lateral ocellus approximately a lateral ocellar diameter as seen in frontal view and ca 2.5 diameters as seen in dorsal view; mandible bi-dentate; labrum semi-oval, 0.5 times as long as basal width; F1 0.7 times as long as wide; F2 0.8–0.9 times as long as wide; F3 0.9–1.0 times as long as wide; gena wide, 1.1 times as wide as eye; supraclypeal area weakly bulging; clypeus with punctures separated by at most a half puncture diameter; frons, paraocular and supraclypeal areas with confluent punctures (20–25 μm); ocello-ocular area with punctures separated by 0.5–2 puncture diameters ( Fig. 7A View Fig ), vertex behind ocelli shiny with sparse punctures; gena shiny, with dense setal pores; face (below antennal sockets) and gena with sparse and thin setae.

MESOSOMA. Mesosoma (including legs) black ( Fig. 7B View Fig ); wings with weak brownish darkening, veins and stigma brown; hind wing with angle between basal (M) and cubital (Cu) veins ca 90°, costal margin with six hamuli; pronotum rounded between dorsal and lateral surfaces; mesoscutum and mesoscutellum with punctures (25–30 μm) separated by 0.5–4 puncture diameters; metafemur enlarged in proximal half, maximum width 0.4 times its length; hypoepimeral area, mesepisternum and lateral parts of propodeum reticulate-rugose; propodeal triangle (metapostnotum) with coarse winding wrinkles and large shiny, finely granulate interspaces ( Fig. 7B, D View Fig ).

METASOMA. T1 almost impunctate, with a few fine punctures along marginal zone ( Fig. 7C View Fig ); remaining terga basally with sparse and fine punctures (5–10 μm); marginal zones impunctate; pygidial plate dull, pointed apically, narrow, 0.8–0.9 times as wide as metabasitarsus; T1–T3 red; sterna tessellate, with tiny shallow setal pores (sparse on S2 and denser on S3–S5).
