Diagnosis.

Female. Face papillate; eye sparsely setose (Fig. 2 D View Figure 2 ). Antenna with 27–28 flagellomeres, first flagellomere 1.4–1.5 × as long as wide (Fig. 2 B View Figure 2 ). Vertex yellow along inner orbits. Mesosoma largely marked with orange and yellow, mesoscutum yellow / orange along notauli and on lateral margins and scutellum orange (Fig. 2 E View Figure 2 ). Fore wing with vein 3 rs-m present, areolet sessile (Fig. 2 A View Figure 2 ); hind wing with nervellus intercepted below the middle (Fig. 2 C View Figure 2 ). Metasomal tergites granulate, banded with yellow posteriorly (Fig. 2 A, F View Figure 2 ); first tergite 1.4–1.5 × as long as posterior width, with latero-median longitudinal carinae present, but weak; second tergite 0.8–1.0 × as long as posterior width; tergites 2–3 each with a strong subapical transverse furrow, granulate (Fig. 2 F View Figure 2 ).

Male. Unknown.

Distribution.

Currently known only from the South of France ( Aubert 1978) and Central Italy (first record). Possibly a Tyrrhenian species.

Remark.

The holotype specimen is generally more robust, with the first tergite 1.4 × and second tergite 0.8 × as long as the posterior width. The Italian specimens are slenderer, but otherwise are the same as the holotype.
