DIAGNOSIS. This species belongs to the reticulatus species-group (refer to

Diagnosis of S. alternatus for group description, above). Sphecodes reticulatus differs from other species of the group by having the marginal zone of T4 impunctate and finely tessellate, T4 usually black in females (in S. alternatus and S. crassanus marginal zone of T4 distinctly punctate, smooth between punctures; T4 red in females).

DESCRIPTIVE NOTES. Hind wing with basal vein weakly curved; costal margin with 8–9 hamuli. Female. Total body length 7.0–10.0 mm. Head strongly transverse, 1.25 times as wide as long. Mesoscutum usually densely punctate,

medially with punctures separated by not more than 1–3 puncture diameters;

mesocutellum irregularly punctate, with punctures separated by 0.1–3 puncture diameters. Metasomal T1–T3 with marginal zones smooth and distinctly punctate,

marginal zone of T4 finely tessellate and impunctate; T1–T3 red, T4 sometimes red basally; pygidial plate dull, 0.5 times as wide as metabasitarsus. Male. Total body length 7.0–10.0 mm. Head transverse, 1.2 times as wide as long; tyloids semicircular across basal 1/7–1/5 of flagellomeres. Mesoscutum densely punctate,

medially with punctures separated by at most 1.5–2 puncture diameters;

mesoscutellum with punctures sparser (1–3). Metasomal T1–T3 red; gonocoxite dorsally without impression.
