Figs 27G , 28A–E , 59 , 68C–D

Diagnosis: The male of this species can be recognized by the shape of surstyli in dorsal view, broad basically, constricted in apical third ( Fig. 28A ); large gonopods in ventral view ( Fig. 28B ); broad phallic guide; ejaculatory ducts strictly bent into phallic guide in lateral view ( Fig. 28C ). The female can be recognized by long ovipositor, curved and reaching the mid coxa ( Fig. 27G ).

Description: MALE: Body length (excluding antennae): 4.5 mm. Head. Scape, pedicel, flagellum and arista dark. Pedicel with three upper dark setae; flagellum light brown, gray pollinose and tapering (LF:WF = 1.7). Eyes meeting for a distance of 13‒14 facets. Frons silver-gray pollinose; vertex shining; occiput gray pollinose with scattered light brown setae. Thorax. Postpronotal lobe light brown with pale setae along the upper margin (up to 0.01 mm). Prescutum and scutum black, light brown pollinose; Scutum with two dark uniseriate rows of intra-alar setae. Scutellum black, silver-gray pollinose, with 12 setae along posterior margin. Subscutellum black, pleura dark brown. Wing. Wing length: 2.4 mm. LW:MWW = 3.4. Wing almost entirely covered with microtrichia. M 1 strongly undulating in middle. Halter length: 0.5 mm. Brown to yellowish, narrowly black at base. Legs. Coxae and trochanters black, gray pollinose, mid coxa with three black anterior setae; hind trochanter with scattered short pale bristle. Femora dark brown with narrow yellow apices, silver pollinose and 5‒8 ventral spines towards apex. All femora with one wrinkled indentation in basal. Tibiae light brown at base, gray pollinose, with two rows of short black setae on anterior and three rows on posterior side. Hind tibia with one wrinkled indentation in middle. Tibiae without distal spines. Tarsi light brown, distitarsi dark, claws light brown with black tips. Abdomen. Ground color brown, tergite 1 covered by densely silver-gray pollinose, with eight short dark lateral setae, tergite 2‒5 with weak silvergray pollinose and with scattered brown setae. Sternites white-yellow laterally with dark mid-line centrally, gray pollinose. Genitalia. Genital capsule in dorsal view: surstyli asymmetrical, both with broad base and constricted in apical third but base of the right boarder than left one, left surstyli knobbed apically, right surstyli curved toward left one apically ( Fig. 28A ), epandrium wider than long. Genital capsule in ventral view: gonopods large, broadened, equal in height ( Fig. 28B ). Genital capsule in lateral view: both surstyli broadened at base, strictly bent in apical third towards sternite ( Fig. 28D‒E ); phallic guide broad, pointed; phallus wavy, bent into phallic guide ( Fig. 28C ).

FEMALE: Body length (excluding antennae): 3.6 mm. Head. Eyes separated. Frons silver-gray pollinose, concaved shortly after ocelli to lower third of frons. Occiput gray pollinose. Pedicel with four upper dark setae and one lower setae. Thorax. Postpronotal lobe light yellow, gray pollinose, with 4–5 light brown setae along the upper margin (up to 0.01 mm). Prescutum and scutum, scutellum black, light brown pollinose in dorsocentral area. Wing. Length: 3.5 mm. LW:MWW = 3.8. Legs. Hind trochanter with 6–8 light brown setae. All femora bearing one wrinkled indentation in basal. Fore femur more widened. Hind trochanter with two wrinkled indentations in middle. Distitarsi with long brown setae at anterior margin. Pulvilli broadened and leaf-shaped; claws long, twice the length of distitarsi. Abdomen. Tergites 1–6 gray pollinose with scattered short light brown setae. Ovipositor. Base of ovipositor dark brown, gray pollinose dorsally, with some scattered short pale setae. Viewed laterally ( Fig. 27G ), base of piercer curved, piercer long and angled between proximal and distal part and reached mid coxa. LP: LB = 2.5. LDP:LPP = 4.0.

Etymology: The specific epithet refers to Oshida, the old name of Khaje mountain and a female name in mythology, from where the holotype specimen was collected.

Specimens examined: HOLOTYPE: IRAN: Sistan & Baluchestan: Zabol , 31°07’N, 61°28’E, 481 m a.s.l., 6.vi.2016, H.
