Sphecodes hyalinatus Hagens, 1882

DIAGNOSIS. This species belongs to the hyalinatus species-group and those members with the pronotum rounded between the dorsal and lateral surfaces. The female differs from other species of the same group by the ventral portion of the mesosoma being dull, finely reticulate-rugulose (shiny, coarsely reticulate-rugose in other species). The male is similar to the eastern Palaearctic species S. murotai , and

S. tanoi in sharing a common genitalic form with oval membranous portion of gonostylus ( Fig. 13 ), but differs from them by the less developed tyloids (covering one third to one half of ventral flagellar surfaces versus more than one half in these other species).

DESCRIPTIVE NOTES. Hind wing with basal vein strongly curved; costal margin with 5–6 hamuli. Female. Total body length 5.0– 7.5 mm. Head transverse,

about 1.2 times as wide as long; clypeus densely punctate, punctures separated by less than a puncture diameter. Mesoscutum with punctures separated by 1–3 (sometimes sparser) puncture diameters. Metasomal T1 impunctate; T2–T3 indistinctly and very finely punctate; T1–T3 red, sometimes T4 red basally; pygidial plate 0.7 times as wide as metabasitarsus. Male. Total body length 5.0–7.0 mm. Head transverse,

about 1.15 times as wide as long; tyloids (from F4 onward) covering about 1/3–1/2

ventral surface of flagellomeres, rarely 3/4 on apical flagellomeres. Mesoscutum and mesoscutellum densely punctate, punctures separated by less than a puncture diameter to contiguous. Metasomal T1 impunctate; T2–T3 indistinctly and very finely punctate; T1–T3 red; gonocoxite dorsally with impression.
