Sphecodes pectoralis Morawitz, 1876

DIAGNOSIS. This species is close to S. cristatus and S. olivieri (refer to Diagnosis for S. olivieri , above), but aside from differences mentioned in the diagnosis for those species, S. pectoralis is also metasomal T2 with marginal zone distinctly punctate (impunctate in S. cristatus and S. olivieri ) and on average smaller in total body size (length 6.5–8.5 mm in females and 5.0–7.0 mm in males, versus 8.0–11.0

mm in females and 7.0–11.0 mm in males of S. olivieri , and 6.0–8.0 mm in females and 7.0–10.0 mm in males of S. cristatus ).

DESCRIPTIVE NOTES. Hind wing with basal vein weakly curved; costal margin with 8–9 hamuli. Female. Total body length 6.5–8.5 mm. Head transverse,

1.23–1.25 times as wide as long; vertex weakly elevated; black to entirely red; face with dense, appressed, snow-white pubescence obscuring integument. Mesosoma black to entirely red; mesoscutum irregularly punctate, with punctures (25–40 μm)

separated by 0.1–3 puncture diameters; mesoscutellum with punctures usually sparser (0.1–5); mesepisternum (partly) and metanotum with dense, appressed,

snow-white pubescence obscuring integument; legs red. Metasomal T1 distinctly punctate, on disc irregularly (10–25 μm / 1–6), denser and finer on marginal zone

(5–15 μm); T1–T5 red; pygidial plate slightly narrower than metabasitarsus. Male.

Total body length 5.0–7.0 mm. Head weakly transverse, 1.10–1.15 times as wide as long; vertex strongly elevated; tyloids weakly developed, narrow, semicircular across basal 1/7–1/5 of flagellomeres. Mesosoma black to entirely reddish brown; mesoscutum densely punctate, with punctures (25–40 μm) separated by 0.1–2 puncture diameters; mesoscutellum with punctures usually sparser (0.1–4); legs red. Metasoma

T1 with marginal zone distinctly punctate; T1–T5 red; gonocoxite dorsally with impression; gonostylus as in Fig. 19 .
