Description
Female [Algeria, vi.1997 (Ammi Moussa), det. Dr. K. Warncke]. BL = 7.5 mm, WL = 5.8 mm.
Color. Flagellum uniformly reddish brown; mandible with apical half reddened; wing membrane
subhyaline; veins and pterostigma reddish brown; posterior part of tegula translucent, reddish brown, anterior
part black; tarsomeres, reddish brown; the rest of body black.
Pubescence. Hairs on head and thorax short, not dense; those on clypeus 300–400μm long, dull white;
those on antennal area of face dense, dull white; those on vertex 250–300μm, yellowish; those on genal area
short (100–200 μm), yellowish; facial fovea brown. Hairs on mesoscutum and scutellum short (200–300μm),
tawny, longer peripherally; those on mesepisternum longer (300–500μm), yellowish; propodeal corbicula
well developed, with pale yellowish long plumose dorsal fringes, internal area with simple hairs, without
anterior fringes; trochanteral flocculus perfect, white; femoral flocculus perfect, dull white; tibial scopa
relatively short, with more or less loose simple hairs; dull white. Hairs on metasomal terga scanty, T1–2 with
broadly incomplete hair bands, T3–4 with complete whitish hair bands. Caudal fimbria brownish, S2–5 with
whitish short subapical fimbriae.
Structure. Head: HL/HW = 0.8, HW:MsW:MtW = 1.1:1:1.1. Vertex narrow, as wide as ocellar diameter,
densely punctate; surface above compound eyes with dense punctures without interval area between them;
OOD:POD:OCD = 3:2:1; FL1 = FL2+FL3, FL2 = FL3; inner margin of eyes subparallel; facial fovea in upper
part occupying 1/2 of distance between compound eye and lateral ocellus, not exceeding the lower level of
antennal socket, FVL = 0.8 mm, FVW = 0.3 mm, facial quadrangle wider than long (nearly 1.1:1). Face above
antennal fossae reticulate without longitudinal rugulae, interrugal space smooth and shiny. Clypeus slightly
convex, with slanting shallow PP (Pd = 30 μm), IS = 0.1, without impunctate median line, shiny and smooth;
CPL = 0.8 mm. Process of labrum short, nearly pointed, shiny; lower paraocular area with very dense
irregular, coarse PP (Pd = 55 μm), IS<0.1. Malar space linear. Genal area narrower than eye, (2:2.5), surface
smooth and shiny with very dense and irregular, nearly large PP (Pd = 30 μm), IS<0.1 near eye.

Mesosoma: Pronotum without humeral angle, with weak lateral ridge and dorsolateral suture, surface
tessellate with scattered PP. Mesoscutum and scutellum smooth and shiny with dense PP (Pd = 10 μm),
IS<0.1. Propodeal enclosure medium sized, not well indicated by lateral boundary line, strongly rugose with
posterior carina, interrugal surface smooth and shiny, dorsolateral area to enclosure similar but with weaker
rugulae. Mesepisternum with dense PP, anterior part reticulate, posterior part with coarse PP, surface smooth
and shiny; anterior part of tegula smooth, with PP.

Metasoma: Metasomal terga with dense, small PP (Pd = 20 μm), IS<0.1, smooth and shiny; posterior
depression of T2–4 distinct, with smaller PP; pygidial plate V-shaped, with microscopic PP, without internal
raised area; S2–5 smooth and shiny with fine and deep PP.
