Figs 25A–F View FIGURE 25 , 56 View FIGURE 56 , 68A–B View FIGURE 68

Diagnosis: This species can be recognized by the asymmetrical surstyli in dorsal view, broadened in basal, left surstylus knobbed apically, right surstylus narrowed in apical half ( Fig. 25A View FIGURE 25 ); gonopods equal in height in ventral view ( Fig. 25B View FIGURE 25 ); small phallic guide in lateral view ( Fig. 25D View FIGURE 25 ).

Description: MALE: Body length (excluding antennae): 3.9 mm. Head. Scape, pedicel, flagellum, arista dark brown. Pedicel gray pollinose in apical half, with three upper setae and 1-2 lower setae. Flagellum gray pollinose and tapering (LF:WF = 3.0); arista dark, with thickened base. Eyes meeting for a distance of 6‒8 facets. Frons dark silver-gray pollinose. Vertex black, lacking pollinosity. Occiput dark and gray pollinose with scattered short black setae. Thorax. Postpronotal lobe light yellow, gray pollinose with 4-6 yellowish setae along the upper margin (up to 0.02 mm). Prescutum, scutum and scutellum black. Scutum with two uniseriate rows of intra-alar setae. Scutellum with 14–16 thin short setae along lateral margin (up to 0.02 mm). Subscutellum black, gray pollinose. Pleura black but dark brown on pteropleuron, hypopleuron and sternopleuron. Wing. Length: 3.85 mm. LW:MWW = 5.13. Wing almost entirely covered with microtrichia. Cross-vein r-m reaches dm at the middle. M 1 strongly undulating in middle. Halter length: 0.4 mm. Whitish, narrowly brown at base. Legs. Coxae dark brown, gray pollinose. Mid coxa with four dark anterior setae. Trochanters brown, smooth. Femora dark with light brown apices, gray pollinose. Mid and hind femora bearing two rows of small spines in apical half and with one wrinkled indentation at the base. Tibiae brown but dark at 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 densely gray pollinose, with 8–10 dark lateral setae (up to 0.11 mm). Tergites 2–5 gray pollinose, with scattered brown setae. Sternites light brown laterally and dark brown centrally, gray pollinose. Genitalia. Genital capsule in dorsal view: epandrium and surstyli brown, gray pollinose. Epandrium wider than long (MLE: MWE = 0.5). Surstyli asymmetrical, elongated ( Fig. 25A View FIGURE 25 ). Both surstyli broad at base, base of left surstylus triangular-shaped, base of right surstylus square-shaped, left surstylus entirely constricted at middle and knobbed apically, right surstylus narrowed in apical half, left surstylus higher than right one ( Fig. 25A View FIGURE 25 ). Genital capsule in ventral view: gonopods wide, equal in height ( Fig. 25B View FIGURE 25 ). Subepandrial sclerite small ( Fig. 25B View FIGURE 25 ). Genital capsule in lateral view: both surstyli bent in middle towards sternite ( Fig. 25E–F View FIGURE 25 ). Phallic guide short, phallus with three ejaculatory ducts ( Fig. 25D View FIGURE 25 ). Ejaculatory apodeme rather spade-shaped ( Fig. 25C View FIGURE 25 ). FEMALE: unknown.

Etymology: The specific epithet refers to Nimrooz, from where the holotype was collected.

Specimen examined: HOLOTYPE: IRAN: Sistan & Baluchestan: Zabol , 31°03’N, 61°22’E, 7.iv.2016, M. Enaiatnia, Malaise trap, JSS51819 (1♂, CNC). GoogleMaps

Distribution: Iran ( Fig. 56 View FIGURE 56 ).

Notes: T. nimroozensis sp. nov. is not genetically similar to any other known Tomosvaryella species. Tomosvaryella pilosiventris is closest to T. nimroozensis sp. nov. with 12.2% pairwise difference (Supplementary Table 1).
