Sphecodes monilicornis (Kirby, 1802)

DIAGNOSIS. This species is close to species of the gibbus species-group (refer to Diagnosis of Sphecodes anatolicus , above), but differs from them by the strongly curved basal vein (1M) in the hind wing, square-shaped head in females (versus round or oval in females of the gibbus species-group), and unique structure of the male gonostylus ( Fig. 17 ).

DESCRIPTIVE NOTES. Hind wing costal margin with 7–8 hamuli. Female.

Total body length 7.0–10.0 mm. Head rounded-rectangular on upper margin, squareshaped as seen in frontal view; vertex sparsely punctate, punctures mostly separated by more than а puncture diameter; distance from top of head to upper margin of lateral ocellus about 3.5 lateral ocellar diameters. Mesoscutum and mesoscutellum irregularly punctate (25–50 μm / 0.5–3); mesepisternum reticulate-rugose;

propodeum laterally strigate-rugose. Metasomal T1 disc indistinctly punctate, with a few very fine punctures; T1–T3 red, T4 partly to entirely red; pygidial plate equal or slightly narrower than metabasitarsus. Male. Total body length 7.0–10.0 mm.

Head rounded, about as long as wide; vertex strongly elevated, distance from top of head to upper margin of lateral ocellus about 2.5–3 lateral ocellar diameters; tyloids weakly developed, semicircular across basal 1/7–1/5 of ventral flagellar surfaces.

Mesoscutum densely punctate, with punctures contiguous to separated by at most

1.5 a puncture diameter. Metasomal T1 finely and sparsely (sometimes indistinctly)

punctate; T1 (usually apically), T2, and T3 red; gonocoxite dorsally without impression.
