Sphecodes trjapitzini Astafurova et Proshchalykin, 2018

DIAGNOSIS. This species is similar to small Palaearctic species with simple mandibles which lack an inner tooth (refer to Diagnosis of S. armeniacus , above).

In female characters S. trjapitzini is closest to S. longuloides and S. longulus ,

having the same sparsely punctate ocello-ocular area with punctures separated by

2–5 puncture diameters that well distinguish theirs from other species of the group where punctures are separated by 0.5–2 puncture diameters. The female of S.

trjapitzini differs from S. longuloides only by smaller body length (3.5 mm versus

5–5.5 mm), but both easy differ from S. longulus by transverse head 1.3 times as wide as long (vesus 1.15 times in S. longulus ). In male characters S. trjapitzini is closest S. longulus and differs from this species only by a slightly larger ratio of the wide of gonostylus to its length.

DESCRIPTIVE NOTES. Hind wing with basal vein strongly curved; costal margin with 5 hamuli. Female. Total body length 3.5 mm. Head transverse, 1.3

times as wide as long; vertex not elevated; antenna and mandibule reddish-yellow;

F1–F3 transverse, 0.6–0.7 times as long as wide. Mesoscutum and mesoscutellum with coarse punctures (15–20 μm / 1–3). Metasomal terga smooth and shiny; T1

almost impunctate, except a few microscopical punctures (3 μm); T2–T4 with fine,

but numerous punctures (5–10 μm / 2–4); marginal zones impunctate, smooth; T1

and T2 reddish-brown. Male. Total body length 3–3.5 mm. Head weakly transverse,

at most 1.15 times as wide as long; tyloids semioval-shaped, not extending beyond middle of each flagellomere. Sculpture of mesosoma and metasoma as in a female;

gonocoxite dorsally without depression; gonostylus oval ( Figs 34, 38 ).
