Redescription. Male. Body length 6.2–6.4 mm ( Fig. 17 A). Head ( Figs. 17 B, C): Eye bare, facet slightly expanded on anterior margin in median part; frons broad on vertex, becoming narrow anteriorly, median part about 0.33–0.34 times of head-width; frontal vitta and frontal-orbital plate with obvious boundary; frons, face and gena with dense silvery grey pollinosity; frontal vitta with thin silvery pollinosity, upper orbital setae 2, frontal setae 3 (developed) and with 5 short setae in 1 row on outer part; parafacial bare, slightly shorter than width of postpedicel; facial ridge low, slightly concave; antenna dark brown, pedicel with thin silvery pollinosity, postpedicel about 3.3– 3.5 times as long as broad (1.9–2.1 times as long as pedicel), arista plumose, the longest setula equal to width of postpedicel; face planate, without facial carina; epistoma not projecting to vibrissal angle; vibrissae asymmetric, left one short while right one strong, right one longer than length of distance between them; genal height about 1/4 of eye height; postocular setae 3 rows, posteriormost row situated in occiput; postgena with black setulae; proboscis short, labella small, with 2 prestomal teeth on posterior margin, prementum shinning, about 5.3 times as long as broad; palpi dark grey, compressed, expanded in distal part, towards apex becoming spoon-shaped, both inner and outer surfaces setulose (more strongly than other species in the group) on apex.

Thorax: Ground color black with dense silvery grey pollinosity; scutellum with brown pollinosity on posterior; acr 0+1 (thin); presutural 6 rows of acrostichal setulae; dc 2+3; ia 1+2, without pra; basal and apical scutellar setae all developed; scutellum bare on lateral surfaces and underneath; notopleuron bare; the median part of anepimeron with numerous bristles; prosternum, meron and katepimeron bare; spiracles brown, posterior one small and with 4 or 5 setae on posterior lower margin; katepisternal setae 1+2.

Wings: Slightly hyaline; veins becoming brown apically; tegula and basicosta yellowish brown; subcostal sclerite yellow; costal spine about as long as crossvein r–m; vein C with ventral setulae; other veins bare; vein R4+5, M and crossvein dm-cu straight; calypteres white; haltere yellowish; WIPs with 4 demarcated color bands (cyan, blue, magenta and yellow) at posterior part of the wing, of which yellow band at dominace ( Fig. 30 O).

Legs: Black except knees yellow; with dense silvery grey pollinosity; fore femur with 1 v row (which become shorter in basal 1/2) and 1 devoloped pd row; fore tibia with 1 preapical d and 1 apical ad; mid legs lost; hind femur with 1 av row (of which 4 setae on distal half developed), 1 developed pv row (of which 3 setae in basal 1/3 developed) and 1 close-set ad row; hind tibia with ununiformly-spaced short setulae rows on each surface, with 17- 19 different-sized developed setae in distal half on av and pv surfaces, with 1 developed preapical d; first hind tarsomere moderately swollen ( Fig. 1 F), with 2 dense and long setulae rows on av surface, shorter than the summed length of other tarsomeres; tarsi shorter than tibia; claws and pulvilli small.

Abdomen: ( Fig. 17 D) Ground color black, oval, with silvery grey pollinosity; tergite 3 with brown patches, tergite 4 dusted with triangular dark brown patches on sides, tergite 5 with developed discal and marginal setae and pair of small dark brown patches on anterior margin which merge with patch on tergite 4.

Female. Body length 6.6–6.8 mm. General characters as in male but differing from male in: frontal vitta, frontal-orbital plate and parafacial with brownish grey pollinosity; gena with silvery grey pollinosity; both vibrissae strong; fore tibia with 1 median p; mid femur with 1 comb-like av row and 5 developed pv in basal 1/3; mid tibia with 1 median ad, 1 median pd, 1 preapical ad and 1 apical d; hind tibia with 1 median ad, 2 v, 1 preapical d and 1 apical ad; first hind tarsomere not swollen.

Distribution. Algeria, Egypt, Tunisia.
