Sphecodes saxicolus Warncke, 1992

DIAGNOSIS. This species is similar to S. intermedius and S. pinguiculus as they all have densely punctate metasomal terga and males with appressed white pubescence on the face both above and below the antennal toruli. The male differs from these species by the weakly developed tyloids extending beyond a half of ventral flagellar surface (at least three quarters of ventral flagellar surface in other species) and oviform gonostylar shape (rectangular and S-shaped in S. intermedius and S. pinguiculus ). The female can be distinguished by the short vertex with a distance from the top of the head to the upper margin of lateral ocellus about two lateral ocellar diameters (this distance is three ocellar diameters in S. intermedius and S. pinguiculus ), and the absence of dense appressed setae on the face.

DESCRIPTIVE NOTES. Hind wing with basal vein strongly curved; costal margin with 5–6 hamuli. Female. Total body length 5.5–6.0 mm. Head transverse,

1.3 times as wide as long, vertex not elevated; clypeus shiny, with punctures separated by 0.5–1 a puncture diameter; F1 transverse, 0.6 times as long as wide; F2 and

F3 slightly transverse, 0.8–0.9 times as long as wide; antenna and mandible brownish to reddish brown; face with sparse pubescence, not obscuring integument. Mesoscutum and mesoscutellum sparsely punctate, punctures (15–25 μm) separated by 1–4

puncture diameters; legs brownish to reddish brown. Metasomal terga with distinct and dense punctures (15–25 μm / 0.5–2), sparser (1–4) on T1; marginal zones impunctate; T1–T3 brownish or red; pygidial plate as wide as metabasitarsus. Male.

Total body length 5.5–6.0 mm. Head transverse, 1.2 times as wide as long, vertex not elevated; F2 long, 1.4 times as long as F3; tyloids semioval-shaped, extending beyond a half of ventral flagellar surface. Mesoscutum sparsely punctate, punctures

(15–25 μm) separated by 1–3 puncture diameters; mesoscutellum with punctures denser and coarser (15–30 μm / 1–2). Metasomal terga densely punctate (5–15 μm /

1–2), marginal zones impunctate; T1–T3 from red to dark brown; gonocoxite with dorsal impression; gonostylus oviform ( Fig. 30 ).
