Sphecodes longulus Hagens, 1882

DIAGNOSIS. This species is similar to small Palaearctic species with simple mandibles (refer to Diagnosis S. armeniacus , above). Sphecodes longulus differs from these species by the weakly transverse female head (1.15 times as wide as long versus 1.2–1.3 in other species). The female is similar to S. longuloides and S.

trjapitzini by sparsely punctate ocello-ocular area with punctures separated by 2–5

punctute diameters (0.5–2 in other species). The male is most close to S. trjapitzini ,

S. turanicus , and S. hirtellus in sharing similar genitalic form with short, oval gonostylus without membranous part ( Fig. 15 ), but differs from two last by a shorter antenna with F2 1.4–1.5 times as long as wide (versus F2 1.7–1.8 as long as wide)

and by the less developed tyloids on the flagellomeres extending at most a half of ventral flagellar surfaces (versus those across 1/2–3/4). The male S. longulus differs from S. trjapitzini only by a slightly smaller ratio of the wide of gonostylus to its length.

DESCRIPTIVE NOTES. Hind wing with basal vein strongly curved; costal margin with 5–6 hamuli. Female. Total body length 4.0–6.0 mm. Head weakly transverse, at most 1.15 times as wide as long; clypeus, at least in its lower half,

with punctures separated by about a puncture diameter; ocello-ocular area with sparse snd fine punctures separated by 2–5 puncture diameters; F1–F3 transverse,

F1 and F2 about 0.6–0.7 times as long as wide, F3 0.8 times as long as wide. Mesoscutum finely punctate (10–20 μm / 1–4). Metasomal T1 impunctate; T2–T3 finely,

sparsely, and usually indistinctly punctate; T1–T3 yellowish red, T4 and T5

brownish; pygidial plate shiny, 0.6 times as wide as metabasitarsus. Male. Total body length 3.5–6.0 mm. Head weakly transverse, at most 1.1 times as wide as long; tyloids semioval-shaped, not extending beyond middle of each flagellomere.

Mesoscutum medially with punctures separated by 1–2 puncture diameters, becoming denser peripherally. Metasomal T1 impunctate, T2–T3 finely but distinctly punctate; T1 and T2 yellowish or brownish-red to red, remaining terga usually darker;

gonocoxite dorsally without impression; gonostylus small, triangular ( Fig. 15 ).
