Scape dark brown, pedicel brown, flagellum light brown. Pedicel with a pair of short upper setae and a single short lower bristle; flagellum tapering and gray-white pollinose (LF:WF = 3.0); arista dark, with thickened base. Eyes converging but not meeting and separat- ed by less than diameter of frontal facets. Frons dark silver-gray pollinose. Vertex black, lacking pollinosity. Occiput dark and gray pollinose.  Thorax.Postpronotal lobe light yellow, gray pollinose with 5–6 yellowish setae along the upper margin (up to 0.03 mm). Prescutum, scutum, scutellum black. Scutum with two uniseriate rows of intra-alar setae and two uniseriate rows of dorsocentral setae. Scutellum with 1–2 thin short setae along lateral margin (up to 0.03 mm). Subscutellum black, gray pollinose. Pleura black but dark brown on pteropleuron, hypopleuron and sternopleuron. Wing. Length: 2.5 mm. LW:MWW = 2.5. Wing almost entirely covered with microtrichia. Crossvein r-m reaches dm at the middle. M 1strongly undulating in middle. Halter length: 0.3 mm. Whitish, narrowly brown at base. Legs. Coxae dark but mid coxa brown, gray pollinose. Mid coxa with two light brown anterior setae. Trochanters brown, smooth. Femora dark with light brown apices, gray pollinose. Hind femur bearing two rows of small spines in apical half with 1–2 wrinkled indentations at base. Tibiae brown but dark at the middle, with two ventral rows of short setae on anterior and three rows on posterior side. Hind tibia with 1–2 wrinkled indentations in middle. Tarsi light brown with scattered brown setae at anterior margin, basitarsi longer than other tarsomeres. Pulvilli yellow. Claws light brown with black tips.  Abdomen.Ground color dark. Tergite 1 gray pollinose, with 5–6 dark lateral setae (up to 0.11 mm). Tergites 2–5 with scattered brown setae. Tergite 5 slightly longer than tergite 4 and almost symmetrical in dorsal view (LT35:WT5 = 1.3, WT5:LT5 = 2.0, T5R:T5L = 1.0). Sternites light brown laterally and dark brown centrally, gray pollinose. Syntergosternite 8 dark. Membranous area ovate in caudal view.  Genitalia.Genital capsule in dorsal view: epandrium and surstyli light brown, gray pollinose. Epandrium wider than long (MLE:MWE = 0.90). Surstyli entirely asymmetrical. Left surstylus slightly rectangular-shaped and rather larger than left one, right surstylus slightly triangular-shaped and curved to left one ( Fig. 36A). Genital capsule in ventral view: gonopods equal in height, right wider than left one, left more sclerotized than right one ( Fig. 36B). Phallus with different-sized ejaculatory ducts, one bearing saw-like teeth along its side ( Fig. 36B). Phallic guide strong, straight with small projection at the base, pointed towards right surstylus ( Fig. 36B). Genital capsule in lateral view: left surstylus with distinct ventromedial projection ( Fig. 36D). Phallic guide strong, elongated, with a distinct membranous sheath basally ( Fig. 36D–E). Ejaculatory apodeme tube-like, bent, with a bulb in its middle ( Fig. 36C).   FIGURE 36.Male genitalia of  Tomosvaryella soziana  sp. nov.,holotype (JSS52193, CNC) A) dorsal view, B) ventral view, C) ejaculatory apodeme, D, E) lateral view.  FEMALE: Body length (excluding antennae): 2.75 mm. Head. Eyes separated. Frons silver-gray pollinose except ocellar triangle, widened in middle (MWF: 0.1 mm; MWF:WFA = 2.4). Occiput gray pollinose.  Thorax.Postpronotal lobe light yellow, gray pollinose with 2–3 light brown setae along the upper margin (up to 0.03 mm). Prescutum and scutum, scutellum black, gray pollinose with scattered setae at anterior supra-alar area.  Wing.Length: 2.5 mm. LW:MWW = 3.3. Legs. Mid coxa with 2–3 black anterior setae. Mid femur bearing two small ventral rows of dark peg-like spines in the apical third. Distitarsi with long brown setae at anterior margin. Pulvilli smaller than distitarsi.  Abdomen.Tergites 1–6 gray pollinose with scattered brown setae. Ovipositor. Base of ovipositor dark brown, gray pollinose, dorsally with some scattered brown setae. Viewed laterally ( Fig. 27H), base of piercer curved, piercer straight, as long as the base. LP:LB = 1.0.   Etymology:The specific epithet refers to the historical name of Khuzestan, from where the specimens were collected.  Specimens examined:   HOLOTYPE: IRAN: Khuzestan: Shush, 32°06’N, 48°26’E,  68 ma.s.l.,  11.iii– 10.v.2015, E. Gilasian, Malaise trap, JSS52193 ( 1♂, CNC);   PARATYPE: IRAN: Khuzestan: Shush, same data as holotype, JSS52205 ( 1♀, CNC).   Distribution: Iran( Fig. 56).  Note:Based on DNA barcoding, this species is genetically similar to  T. spinula  sp. nov., differing by 1.8% (pairwise divergence). The male and female are genetically identical (Supplementary Table 1). JSS52193 2015-03-11 2015-05-10 2015-03-11 CNC E.
