Description. FEMALE. Fore wing 12.3 mm.

Head. Ventral tooth of mandible slightly longer than dorsal tooth. Clypeus apical area delimited by smooth border; clypeal margin with two small delicate teeth. Antenna with 24 flagellomeres; white band starting at flagellomere V; 7 flagellomeres at least 50% white.

Mesosoma . Mesopleuron glabrous. Subalar prominence strongly protruding, somewhat flattened dorso-ventrally and more or less elongate ( Fig. 150). Sulcus between sternaulus and scrobe absent. Posterior transverse carina of mesosternum absent. Lower metapleuron weakly striate. Propodeum: area in front of anterior transverse carina laterally with weak rugosity, medially with faint micropunctures, and two incomplete ridges extending from carina towards anterior margin. Propodeal apophyses present as weak scale-like structures, part of complete and bell-shaped posterior transverse carina, which extends to latero-posterior margin. Area between transverse carinae obliquely striate-rugose; area behind posterior transverse carina densely rugose. Fore wing in Fig. 209; vein 3-Cu 1.37 length of 4-Cu. Hind wing in Fig. 249.

Metasoma. Postpetiole dorso-anteriorly convex or flat; dorsolateral and median dorsal carinae absent; petiolar spiracles in dorsal view not prominent. Ovipositor 1.33 length of hind tibia. Apex of lower valve with 13 teeth.

Color. Yellow, brown with orange tone, and dark brown. Lateral pattern as in Fig. 11. Head yellow, except apical margin of apical area of clypeus translucent brown, supra-antennal area and vertex with medio-longitudinal stripe with 0.4 width of interocular distance, reddish brown below ocelli, dark brown behind; malar space and occiput dorsally, brown. Mesosoma laterally and ventrally mostly yellow, dorsally brown with orange tone, except as follows. Pronotum dorsally along anterior margin with wide yellow stripe, not medially interrupted. Propleuron entirely yellow. Mesoscutum centrally, at level of tegula, with large yellow spot, dark brown shortly in front, and behind it in between notauli, remaining of mesoscutum brown with orange tone. Scutellum and postcutellum entirely yellow. Propodeum as in Figs 11–12, dark brown around its carinae. All femora and tibiae brownish yellow. Fore t1 and about basal half of fore t2 and mid t1 brownish yellow, remaining of fore and mid tarsi dark brown; hind t1 basal 0.9 brown, apex and t2–3 white, t4–5 dark brown. Metasoma dorsally dark brown to black, except as follows. Postpetiole yellow. T2–7 apical margin with moderately wide yellow stripe. T8 laterally with wide yellow area, apical margin with very narrow yellow stripe.

Morphological variation. Differences in relation to the description and illustrations for this species provided by Alayo and Tzankov (1974) are as follows. Fore wing length 7–11 mm. Areas described here as yellow were described as “white” by Alayo and Tzankov. Ratio 3-Cu/4-Cu, as measured from the wing illustration provided by the authors, is 1.74 (probably inaccurate). Propodeum with black instead of brown, its apical black spot shaped as a “W” much larger than represented in Fig. 12 herein.

MALE. According to Alayo and Tzankov (1974), similar to female, except for “color pattern highly variable; propodeal apophyses weaker; hind t2–4 white.”

Comments. The following features are characteristic: overall color pattern, propodeal carinae closely approximated and similarly shaped, and the subalar prominence conspicuously protruding, semicircular and somewhat dorso-ventrally flattened.
