Sphecodes spinulosus Hagens, 1875

DIAGNOSIS. This species is similar to the southern European S. majalis Pérez,

1903 and S. barbatus Blüthgen, 1923 as they all have well-developed spines on the outer surface of the male metatibiae and the long female antenna with F2 square (as long as wide). Sphecodes spinulosus differs from these species by the presence of a distinct preoccipital carina. The female also differs in the short clypeus that is twice as long as wide (three times as long as wide in S. majalis and S. barbatus ), while the male differs in the size of the tyloids on the flagellum (semicircular on basal

1/7–1/5 and widely linear across remainder of flagellomeres versus only narrowly linear across remainder of flagellomeres as seen in lateral view in S. majalis and S.

barbatus) and the form of the gonostylus, large and elongated backwards from apex of gonocoxite ( Fig. 33 ) (small and not protudes from apex of gonocoxite in S. majalis and S. barbatus ).

DESCRIPTIVE NOTES. Hind wing with basal vein strongly curved; costal margin with 7–9 hamuli. Female. Total body length 8.0–11.0 mm. Head strongly transverse, 1.25 times as wide as long; vertex not elevated, distance from top of head to upper margin of lateral ocellus about two lateral ocellar diameters; preoccipital carina present. Mesoscutum densely punctate, punctures (20–30 μm) separated mostly by less than a puncture diameter; mesoscutellum with impunctate areas.

Metasomal T1 distinctly punctate (20–25 μm / 1–4; on anterior half with a few punctures); tergal marginal zones impunctate except for anterior half of T1 with dense punctures; T1–T3 red, T4 usually red basally. Male. Total body length 9.0–

11.0 mm. Head weakly transverse, 1.1 times as wide as long; vertex weakly elevated, distance from top of head to upper margin of lateral ocellus about two lateral ocellar diameters; preoccipital carina present, complete; tyloids semicircular across basal 1/7–1/4 (at least from F4 onward) and widely linear across remainder of flagellomeres as seen in lateral view. Mesoscutum and mesoscutellum densely punctate, punctures separated by less than a puncture diameter. Metasomal T1

(including marginal zone) densely punctate (20–25 μm / 0.5–2); T1 red laterally and apically, T2 and T3 entirely red, T4 red basally; gonocoxite dorsally without impression.
