Figs 22A–D , 53 , 67E –F

Diagnosis: This species can be recognized by the shape of surstyli in dorsal view, right surstylus rectangular-shaped and left surstylus roughly club-shaped ( Fig. 22A ); left surstylus with apicoventral projection in lateral view ( Fig. 22C ); long phallic guide, straight dorsally, wavy ventrally in lateral view ( Fig. 22C–D ).

Scape and pedicel dark; pedicel with a pair of short upper setae and 1–2 short lower setae; flagellum light brown, tip paler than base, tapering and gray pollinose (LF:WF = 2.6); arista dark, with thickened base. Eyes converging but not meeting and separated by less than diameter of frontal facets. Frons dark, silver-gray pollinose, vertex dark, lacking pollinosity, bearing an elevated ocellar triangle; vertex dark, lacking pollinosity; occiput dark, gray pollinose. Thorax. Pleura, prescutum, scutum and scutellum dark. Pleura gray pollinose. Postpronotal lobe yellow, weakly gray pollinose and with 2–3 light brown postpronotal setae along upper margin. Prescutum and scutum narrowly gray pollinose, with two uniseriate dorsocentral rows of setae and some supra-alar setae. Scutellum gray pollinose, with about 2–3 thin short setae along posterior margin (up to 0.03 mm). Subscutellum gray pollinose. Wing. Length: 2.5 mm. LW:MWW = 2.5. Wing almost entirely covered in microtrichia. M 1 gently undulating. Halter length: 0.33 mm. Base and stem brown, knob paler than base. Legs. Coxae dark, gray pollinose. Mid coxa with 2–3 light brown setae on apical margin. Trochanters dark, smooth. Femora dark brown, slightly light brown at apex, gray pollinose. Fore femur bearing two smaller anteroventral spines in basal third, Fore and hind femora with 1–2 wrinkled indentations in basal. Tibiae dark brown, distinctly light brown in basal third, gray pollinose with one wrinkled indentation in middle, hind tibia with some light brown setae in apical third. Tarsi light brown and paler than tibiae, gray pollinose, with some light brown setae dorsally. Pulvilli yellow. Claws light brown with black tips. Abdomen. Ground color dark, gray pollinose. Tergite 1 with six to eight strong lateral setae. Tergites 1–5 with scattered brown setae. Syntergosternite 8 dark, brown pollinose. Genitalia. Genital capsule in dorsal view: epandrium brown, wider than long (MLE:MWE = 0.71). Surstyli brown and asymmetrical, right surstylus rectangular-shaped and left surstylus roughly club-shaped, wider than right one, tip of left surstylus rounded ( Fig. 22A ). Genital capsule in ventral view: gonopods equal in height, rather broad and almost symmetrical ( Fig. 22B ); phallic guide strong and long, reaches in middle of surstyli, subepandrial sclerite wide, rather rectangular-shaped ( Fig. 22B ). Genital capsule in lateral view: both surstyli rectangular-shaped, bent towards sternite ( Fig. 22C–D ); left surstylus with apicoventral projection ( Fig. 22C ); phallic guide thin and long, straight dorsally, wavy ventrally ( Fig. 22C–D ); phallus trifid with three ejaculatory ducts, one bearing small teeth along basal two thirds ( Fig. 22C–D ). FEMALE: unknown.

Etymology: The specific epithet refers to “Kiansi”, the historical name of a Hamoun wetland, from where the specimens were collected. The name is formed as a feminine noun in the genitive case.
