Diagnosis: This species can be recognized by the elongated surstyli in dorsal view, constricted in basal third and curved to each other ( Fig. 37A View FIGURE 37 ); epandrium longer than wide ( Fig. 37A View FIGURE 37 ); gonopods elongated with a small projection ( Fig. 37D View FIGURE 37 ); phallus with three short ejaculatory ducts, one with a finger-like projection and a feather-like projection, another one with a small spine in its middle in lateral view ( Fig. 37B–C View FIGURE 37 ); hind trochanter with two distinct projections (Fig. 47F).
Description: MALE: Body length (excluding antennae): 2.5 mm. Head. Scape and arista dark, pedicel and flagellum light brown. Pedicel with one or two short upper pale setae; flagellum tapering and gray-white pollinose (LF:WF = 2.4). 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 pale setae. Thorax. Postpronotal lobe light yellow, gray pollinose with 3–4 short setae along the upper margin (up to 0.02 mm). Prescutum, scutum, scutellum black. Scutum with two uniseriate rows of intra-alar setae and two uniseriate rows of dorsocentral setae. Scutellum with 3–4 thin short setae along lateral margin (up to 0.01 mm). Subscutellum black, gray pollinose. Pleura brown. Wing. Length: 2.5 mm. LW:MWW = 3.3. Wing almost entirely covered with microtrichia. Cross-vein r-m reaches dm at the middle. M 1 moderately undulating in middle. Halter length: 0.33 mm. Whitish, narrowly brown at base. Legs. Fore and mid coxae light brown, hind coxa brown, gray pollinose. Mid coxa with three dark anterior setae. Trochanters brown, gray pollinose. Hind trochanter with two distinct projections, longer one (0.08 mm) is thorn-like and located on basal margin with two short setae at its apex and wider one located on apical margin (Fig. 47F). Femora brown with light brown apices, gray pollinose. All femora with one wrinkled indentations at base. Tibiae brown but light brown in basal third, 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 lighter than other tarsomeres. Pulvilli yellow. Claws light brown with black tips. Abdomen. Ground color dark brown. Tergite 1 densely gray pollinose, with 4–5 light brown lateral setae (up to 0.11 mm). Tergite 2–5 gray pollinose, with scattered brown setae. Sternites light brown laterally and dark brown centrally. Genitalia. Genital capsule in dorsal view: epandrium and surstyli brown, gray pollinose. Epandrium longer than wide (MLE:MWE = 1.14). Surstyli rather symmetrical. Both surstyli elongated, restricted in basal third, curved to each other at apex, left is higher than right one ( Fig. 37A View FIGURE 37 ). Genital capsule in ventral view: gonopods elongated and equal in height with a small projection ( Fig. 37D View FIGURE 37 ). Subepandrial sclerite elongated ( Fig. 37D View FIGURE 37 ). Genital capsule in lateral view: both surstyli bent towards sternite, right is broader than left one ( Fig. 37B–C View FIGURE 37 ). Phallic guide strong, phallus with three ejaculatory ducts, one with finger-like projection and feather-like projection, another one with a small spine in its middle ( Fig. 37B–C View FIGURE 37 ). FEMALE: Body length (excluding antennae): 2.7 mm. Head. Eyes separated, pedicel without short setae. Frons gray pollinose. Occiput gray pollinose with scattered dark setae. Thorax. As in male. Wing. Length: 2.2 mm. LW:MWW = 2.09. Legs. As in males except for smooth hind trochanter. Abdomen. As in males. Ovipositor. Base of ovipositor dark brown with some gray pollinosity. Viewed laterally ( Fig. 27D View FIGURE 27 ), piercer short and straight. LP:LB = 1.8. LDP:LPP = 3.0.
Etymology: The specific name is derived from the Latin word spinula, meaning thorn, referring to the thornlike projection on its hind trochanter. Specimens examined: HOLOTYPE: IRAN: Zabol, 31°03’N, 61°22’E, 470 m a.s.l., 4.vii.2016, M. Enaiatnia, Malaise trap, JSS51924 (1♂, CNC); PARATYPE: IRAN: Zabol, 31°03’N, 61°22’E, 470 m a.s.l., 7.iv.2016, M. Enaiatnia, Malaise trap, JSS51820 (1♀, CNC). Distribution: Iran ( Fig. 63 View FIGURE 63 ). Note: Based on DNA barcodes, this species is genetically similar to T. soziana sp. nov., differing by 1.8 % (pairwise divergence). The male and female differ by 0.0% (Supplementary Table 1).
