Sphecodes schwarzi Astafurova et Proshchalykin, 2015

DIAGNOSIS. This species belongs to the miniatus species-group, with the same length and transverse F1–F 3 in the female. The female differs from other species of the group by the well-developed pubescence of the paraocular area with dense,

strongly plumose, white setae. The male is similar to S. haladai , S. larochei , S.

sandykachis and S. marginatus in the densely punctate T1 and small, triangular membranous portion of the gonostylus ( Fig. 32 ), but differs from S. haladai and S.

larochei by the coarse and denser tergal punctation (punctures separated by at most a puncture diameter versus 1–3 in other species); and more difficult distinguished from S. marginatus and S. sandykachis , but an average has shorter tyloids.

DESCRIPTIVE NOTES. Hind wing with basal vein strongly curved; costal margin with 5–6 hamuli. Female. Total body length 4.5–5.5 mm. Head transverse,

about 1.25 times as wide as long; clypeus with punctures separated by about a puncture diameter (10–25 μm / 0.3–1.5), integument between punctures smooth and shiny. Mesoscutum and mesoscutellum relatively sparsely punctate medially (15–

25 μm / 1–4 or more), becoming denser peripherally. Metasomal T1 smooth and shiny, almost impunctate, with a few fine punctures (3–10 μm); remaining terga with dense and fine punctures (10–15 μm / 0.5–2), becoming sparse along marginal zones; marginal zones impunctate; T1–T2 reddish brown, usually lighter on marginal zones; remaining terga brown; pygidial plate narrower than metabasitarsus. Male.

Total body length 5.0– 5.5 mm. Head weakly transverse, 1.1 times as wide as long;

tyloids on F3 covering about 1/2 ventral flagellar surface, on F4 and F5 about 1/2–

2/3, about 2/3–4/5 on remaining flagellomeres. Mesoscutum with deep punctures

(15−25 μm / 1–4), becoming denser peripherally. Metasomal terga densely punctate with punctures separated by at most a puncture diameter; marginal zones impunctate; metasoma dark brown; gonocoxite dorsally with impression;

gonostylus small, triangular.
