Diagnosis: This species can be recognized by the shape of surstyli, which are rectangular-shaped and flatted apically in dorsal view ( Fig. 2A View FIGURE 2 ), and almost straight in lateral view ( Fig. 2D–E View FIGURE 2 ); right gonopod with a long projection in ventral view ( Fig. 2B View FIGURE 2 ); wide subepandrial sclerite basally in ventral view ( Fig. 2B View FIGURE 2 ); wide gonopods in ventral view ( Fig. 2B View FIGURE 2 ); three small ejaculatory ducts, one with some teeth in basal half ( Fig. 2D View FIGURE 2 ). Based on genitalia characters, this species is close to T. susa sp. nov. and T. helwanensis ( Collin, 1949) . It differs from T. susa ( Fig. 40A‒D View FIGURE 40 ) in the different shape of the surstyli at the apex in dorsal view, flattened (not rounded) and from T. helwanensis ( Kehlmaier et al. 2019: Fig. 8 View FIGURE 8 ) in the different shape of the surstyli in dorsal view, rectangular shaped ( Fig. 2A View FIGURE 2 ); with a broad and short phallic guide in lateral view ( Figs 2D‒E View FIGURE 2 ).

Description: MALE: Body length (excluding antennae): 2.8 mm. Head. Scape dark, pedicel dark brown, flagellum light brown; pedicel with three short upper setae; flagellum tapering (LF: WF = 4.0); arista brown with a dark spot near the base. Eyes meeting for a distance of 5–7 facets. Frons silver-gray pollinose. Vertex black, lacking pollinosity. Occiput dark and gray pollinose. Thorax. Postpronotal lobe light yellow, gray pollinose with 2–4 small setae along the upper margin (up to 0.04 mm). Prescutum and scutum black, with a row of supra-alar setae and uniseriate rows of intra-alar setae. Scutellum black, silver-gray pollinose, with about 14–18 thin setae along posterior margin (up to 0.08 mm). Subscutellum and pleura dark brown. Wing. Length: 2.1–2.4 mm. LW: MWW = 2.5. Wing almost entirely covered with microtrichia. Cross-vein r-m reaching cell dm at the middle. M 1 strongly undulating in middle. Halter length: 0.4 mm. Whitish, narrowly light brown at base. Legs. Dark brown but narrowly yellow at apex of femora, tibiae and tarsi. Trochanters and Femora partly gray pollinose. Trochanters smooth. Mid and hind femora bearing two rows of dark, peg-like anteroventral spines in apical one third. Fore, mid and hind femora with 1–2 wrinkled indentations in basal quarter. Tibiae with two rows of short setae on anterior and three rows on posterior side. Hind tibia with 1–2 wrinkled indentations in the middle. Tarsi yellowish, gray pollinose. Pulvilli shorter than distitarsi. Claws white with black tips. Abdomen. Ground color dark brown. Tergite 1 entirely gray pollinose with 12–16 yellowish long lateral setae (up to 0.2 mm). Tergites 1–5 with scattered yellowish setae (up to 0.08 mm). Sternites light brown laterally and dark brown centrally, gray pollinose. Syntergosternite 8 dark, gray pollinose. Viewed laterally, higher than long (LS8:HS8 = 0.8). Membranous area absent. Genitalia. Genital capsule in dorsal view: epandrium and surstyli brown, gray pollinose. Epandrium wider than long (MLE:MWE = 0.8). Surstyli rather symmetrical, rectangular-shaped, slightly curved to each other at apex, rather flatted apically ( Fig. 2A View FIGURE 2 ). Genital capsule in ventral view: gonopods wide, large and slightly equal in height, right wider than left one with elongated projection, subepandrial sclerite wide basally, phallic guide strong, slightly straight ( Fig. 2B View FIGURE 2 ). Genital capsule in lateral view: surstyli longer than wide, slightly straight, rounded at apex ( Figs 2D–E View FIGURE 2 ). Phallic guide strong, pointed apically ( Fig. 2D View FIGURE 2 ); phallus with three small ejaculatory ducts, one bearing some saw-like teeth in basal half ( Fig. 2D View FIGURE 2 ). Ejaculatory apodeme tube-like, bent, with a bulb in its middle ( Fig. 2C View FIGURE 2 ).

FEMALE: Body length (excluding antennae): 3.2 mm. Head. Eyes separated; with enlarged frontal facets. Frons gray pollinose in lower half. Occiput gray pollinose with scattered light brown setae near ocelli. Thorax. As in male. Wing. Length: 2.75 mm. LW:MWW = 2.08. Legs. As in males except for longer setae on distitarsi. Abdomen. As in males. Ovipositor. Base of ovipositor dark brown with some gray pollinosity. Viewed laterally ( Fig. 27A View FIGURE 27 ), piercer straight. LP:LB = 1.6. LDP:LPP = 1.9.

Etymology: The specific epithet ampliasa is derived from the Latin “amplias”, which means widened or extended, referring to the extended gonopods.

Distribution: Israel ( Fig. 49 View FIGURE 49 )

Note: DNA barcodes of this species are closest to T. susa sp. nov., differing by 0.8% pairwise divergence. Male and female were both sequenced and are genetically identical (Supplementary Table 1).
