Sphecodes scabricollis Wesmael, 1835

DIAGNOSIS. This species is similar to the North African S. atlanticus Warncke,

1992 and Japanese S. ikudomei Mitai et Tadauchi, 2013 , S. nambui Tsuneki, 1983 ,

and S. nipponicus Yasumatsu et Hirashima, 1951 in the flat genal area, the developed preoccipital lateral carina, the densely punctate head and mesoscutum (with punctures separated by at most 1.5–2 puncture diameters in female and areolate in male), and in the similar gonostylar shape of males ( Fig. 31 ). The species differs from S. nipponicus by the red T1–T 3 in males (black in S. nipponicus ), and in the strongly developed median carina on the interantennal elevation in females (absent in S. nipponicus ). The male of S. scabricollis also differs from other two Japanese species in the weakly developed tyloids (semicircular across basal 1/6–1/4 of ventral flagellar surfaces versus those at least widely linear across remainder of flagellomeres as seen in lateral view in other species); from S. atlanticus by sparser punctate metasomal terga with punctures separated by 1–3 punctures diameters (at most a puncture diameters in S. atlanticus ).

DESCRIPTIVE NOTES. Hind wing with basal vein weakly curved; costal margin with 8–9 hamuli. Female. Total body length 9.0–12.0 mm. Head strongly transverse, 1.3 times as wide as long; vertex strongly elevated, sometimes with weak (indistinct) longitudinal ridge; distance from top of head to upper margin of lateral ocellus about two lateral ocellar diameters. Mesoscutum densely punctate and medially with punctures separated by at most 1.5–2 puncture diameters. Metasomal terga with punctures separated by 1–5 punctures diameters, sparser and often almost impunctate on T1; marginal zones impunctate, sometimes except tiny and sparse punctures on T1 zone. Metasomal T1 and T2 red, T3 usually red basally;

pygidial plate slightly narrower than metabasitarsus. Male. Total body length 7.0–

12.0 mm. Head weakly transverse, 1.1 times as wide as long; vertex elevated, distance from top of head to upper margin of lateral ocellus about two lateral ocellar diameters; tyloids semicircular across basal 1/6–1/4 of flagellar surfaces. Mesoscutum and mesoscutellum areolate (coarse punctures contiguous). Metasomal terga with punctures separated by 1–3 punctures diameters; marginal zones impunctate, except on T1 with tiny punctures. T1 red laterally and apically, T2 red, T3 red basally;

gonocoxite dorsally without impression.
