Wing: 1.0– 1.1 mm. <i>Head</i>: slightly longer than high; eyes dichoptic, separated at vertex by 1× distance between lateral ocelli; occiput brown above, with yellow line along posterior eye margin; brown medially; frons white, slightly depressed medially, with brown spot medially; face white; antennae pale brown; scape short, subtrapezoidal; pedicel subconical, wider than long; first flagellomere conical, length 2× width; second flagellomere thin, cylindrical, length subequal to first flagellomere, with minute transparent apical style; mentum brown; clypeus brown, as long as oral margin; proboscis brown, length subequal to head length; labrum brown, sclerotized, stiff, pointed apically, length subequal to head height.</p><p><i>Thorax</i> (Fig. 9). Mesonotum matte brown; yellow dorsolaterally from humeral callus to post alar callus; yellow interhumeral marks coalesced with yellow humeral calli; admedian vittae yellow, distinct to yellow prescutellar area; scutellum yellow with brown laterally; mesonotal disc and dorsum of scutellum with short fine white hairs; pleura bare, yellow, with black on following: anteroventral corner of anepisternum and anepimeron, lower half of katepisternum; propleuron yellow, halter stem and knob brilliant white.</p><p><i>Legs</i>. Coxae brown; femora brown basally, yellow at apex; tibiae and tarsal segments 1–2 yellow, tarsal segments 3–5 brown.</p><p><i>Wing</i> (Fig. 9). Elongate, length 3.5× width; subhyaline; veins brown to pale brown; costa ends beyond end of R 4+5; vein Sc incomplete; Rs faded basally at connection with R 1; R 4+5 straight to wing margin; vein M 1 curved toward wing margin; M 2 straight; cell dm open apically; CuP thick, straight to wing margin; CuA evanescent; anal cell open at wing margin; fringe of hair on posterior margin of wing.</p><p><i>Abdomen</i>. Brown dorsally and at extreme lateral tip of tergites; tergites laterally with large white patch of color; sternites white; tergites with sparsely scattered minute white hairs.</p><p><i>Genitalia</i>.

This species occurs only in Eastern Morocco (Map 1), where it inhabits coastal habitats along Mediterranean coast under a semi-arid bioclimate.</p><p><b>Etymology</b>.
