Tomosvaryella hamounensis Motamedinia & Skevington View in CoL sp. nov.
Figs 17A–E View FIGURE 17 , 27J View FIGURE 27 , 47B, 51, 67C–D
Diagnosis: This species can be recognized by the shape of surstyli in dorsal view, symmetrical, broadened apically ( Fig 17A View FIGURE 17 ), both surstyli rather rectangular-shaped in lateral view ( Fig. 17 D–E View FIGURE 17 ); epandrium wider than long ( Fig. 17A View FIGURE 17 ); hind trochanter expanded apically with a small projection (Fig. 47B). Based on the shape of surstyli in dorsal view, this species resembles T. nodosa and T. pruinosa . It differs by having broader surstyli apically and lacking a hypandrial apodeme ( Fig 17B View FIGURE 17 ). Additionally, the hind trochanter of T. pruinosa lacks the small projection found in T. hamounensis sp. nov. (Fig. 47B) and T. nodosa (Fig. 47C).
Description: MALE: Body length (excluding antennae): 2.5–2.7 mm (n = 11). Head. Scape dark, pedicel and flagellum brown, arista light brown. Flagellum long tapering and gray-white pollinose (LF:WF = 5.0). Eyes meeting for a distance of 10–12 facets. Frons dark silver-gray pollinose. Vertex black, lacking pollinosity, bearing an elevated ocellar triangle. Occiput dark and gray pollinose. Thorax. Postpronotal lobe light yellow, gray pollinose with 3–5 yellowish setae along the upper margin (up to 0.03 mm). Prescutum, Scutum, Scutellum black. Scutum with two short uniseriate rows of intra-alar setae and two uniseriate rows of dorsocentral setae. Scutellum gray pollinose with 8–10 thin short setae along lateral margin (up to 0.01 mm). Subscutellum black, gray pollinose. Pleura brown. Wing. Length: 2.2–2.8 mm. LW:MWW = 1.6. 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. Coxae brown, gray pollinose. Mid coxa with two or three short dark anterior setae. Trochanters brown, gray pollinose. Hind trochanter broader apically with small projection with some short setae (Fig. 47B). Femora brown with light brown apices, gray pollinose. All femora with one wrinkled indentations at base. Tibiae light brown but darker in 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. Pulvilli yellow. Claws light brown with black tips. Abdomen. Ground color brown. Tergite 1 densely gray pollinose, with 3–5 brown lateral setae (up to 0.08 mm). Tergite 2–5 gray pollinose, with scattered brown setae. Genitalia. Genital capsule in dorsal view: epandrium and surstyli light brown. Epandrium wider than long (MLE:MWE = 0.54). Surstyli rather small and symmetrical. Both surstyli broadened at the middle, with an inner small projection at apex ( Fig. 17A View FIGURE 17 ). Genital capsule in ventral view: gonopods rather equal in height ( Fig. 17B View FIGURE 17 ). Subepandrial sclerite small and triangular-shaped ( Fig. 17B View FIGURE 17 ). Genital capsule in lateral view: both surstyli rather rectangular shape, left surstylus with small ventroapical projection and right surstylus with ventrobasal projection ( Fig. 17D–E View FIGURE 17 ). Phallic guide strong, phallus with three ejaculatory ducts. Ejaculatory apodeme tube-like, bent, with a bulb in its middle ( Fig. 17C View FIGURE 17 ).
FEMALE: Body length: 2.6–2.7 mm (n = 5). Frons gray polllinose, widened in middle. Occiput gray pollinose. Eyes separated. Long tapering flagellum (LF:WF = 3.5). Scutum gray pollinose with two row dorsocentral setae. Pleura dark brown, silver-gray pollinose. Wing length: 1.9‒2.0 mm. LW:MWW = 2.1‒2.3. Fore femur bearing two smaller anteroventral spines in basal third, hind femur with 1–2 wrinkled indentations in basal. Pulvilli smaller than distitarsi. Tergites 1–6 with scattered gray pollinose. Tergite 8 brown, rounded, gray pollinose, distal part of piercer straight ( Fig. 27J View FIGURE 27 ). LP:LB = 1.3‒1.4. LDP:LPP = 2.8‒2.9.
