Figs 13A‒D View FIGURE 13 , 27E View FIGURE 27 , 51 View FIGURE 51 , 67A–B View FIGURE 67

Diagnosis: This species can be recognized by the rectangular shape of both surstyli in dorsal view ( Fig. 13A View FIGURE 13 ); long gonopods; sclerotized hypandrium with long hypandrial apodeme and a pair of membranous sheaths in the middle in ventral view ( Fig. 13D View FIGURE 13 ); straight phallic guide with a few distinct dorsolateral spines in lateral and ventral view ( Fig. 13B‒D View FIGURE 13 ). Based on the shape of the surstyli, this species is closely related to kuthyi group ( Tomosvaryella cyprusensis sp. nov., T. freidbergi , T. hispanica , T. israelensis , T. kuthyi , T. parakuthyi ). It differs by the round syntergosternite 8 in dorsal view ( Fig. 13A View FIGURE 13 ), long gonopods in ventral view ( Fig. 13D View FIGURE 13 ) and a few dorsolateral spines on phallic guide in lateral and ventral view ( Fig. 13B‒D View FIGURE 13 ).

Description. MALE: Body length: 2.2‒2.9 mm. Head. Frons silver-gray pollinose. Eyes meeting for a distance of four facets. Pedicel with a pair of dorsal setae; flagellum tapering (LF:WF = 1.9‒2.1), distinctly paler. Thorax. Postpronotal lobe pale, gray pollinose with about 2‒3 postpronotal gray setae along upper margin. Prescutum and scutum black, silver-gray pollinose, with uniseriate dorsocentral row of brown setae and some distinct patches of long supra-alar hairs behind postpronotal lobes. Scutellum black, silver-gray pollinose with 8‒10 dark brown se- tae along the upper margin (up to 0.02 mm). Subscutellum black and pleura brown. Wings. Wing length: 2.3‒2.5 mm. LW:MWW = 2.6‒3.0. Wing almost entirely covered with microtrichia. Cross-vein r-m reaching cell dm at the middle. Halter length: 0.3 mm. Yellow, narrowly brown at base. Legs. Legs dark brown, narrowly yellow at apex of femora, base of tibiae and tarsi. Hind trochanter with a patch of dark brown bristle in the middle. Femora with posteroventral row of black spines and anteroventrally with a row of spines on apical third. Tibiae with two rows of short brown setae on anterior and three rows on posterior side. Pulvilli shorter than distitarsi. Claws white with black tips. Abdomen. Ground color of abdomen dark, gray pollinose; tergite 1 with 3‒4 dark lateral setae in both sides, tergites normally covered with distinct bristly brown setae. Sternite brown, lighter than tergites, gray pollinose; syntergosternite 8 dark brown with scattered brown setae, membranous area large, enlarged towards tip of abdomen and occupying more than half the width of syntergosternite 8. Epandrium darker than surstyli, higher than long (LS8: HS8 = 0.7–0.8); Genitalia. Genital capsule in dorsal view: surstyli rather symmetrical, rectangular-shaped. Left surstylus slightly larger and wider than right one ( Fig. 13A View FIGURE 13 ). Genital capsule in ventral view: gonopods unequal and long, left slightly higher than right one; lobes of hypandrium sclerotized, with a pair of membranous sheaths covered by small hairs in the middle of hypandrium and with long hypandrial apodeme ( Fig. 13D View FIGURE 13 ). Genital capsule in lateral view: left surstylus bent towards sternite in apical third, right surstylus gently curved toward sternite ( Fig. 13B–C View FIGURE 13 ); phallus straight and trifid. Phallic guide straight with few (2–3) short spines laterally ( Fig. 13B–C View FIGURE 13 ). Ejaculatory apodeme tube-like, bent, with a bulb in its middle ( Fig. 13D View FIGURE 13 ).

FEMALE: Body length: 2.0 mm. Frons dark, widened in middle. Occiput gray pollinose. Eyes separated, with enlarged frontal facets. Long tapering flagellum. Scutum gray pollinose with two row dorsocentral setae and uniseriate rows of supra-alar setae. Wing length: 1.9‒2.0 mm. LW:MWW = 2.1‒2.2. Femora with posteroventral row of black spines and anteroventrally with a row of spines on apical third. Pulvilli smaller than distitarsi. Tergites 1–6 with scattered brown and black setae. Tergite 8 brown, rounded, gray pollinose, distal part of piercer straight and long ( Fig. 27E View FIGURE 27 ). LP:LB = 1.9‒2.1. LDP:LPP = 1.8‒2.0.

Etymology: The specific epithet refers to the Emirates, from where the specimens have been collected.

Distribution: United Arab Emirates ( Fig. 51 View FIGURE 51 ).

Note: Based on DNA barcodes, Tomosvaryella emaratensis sp. nov. is genetically most similar to T. minuscula , differing by 2.2% (pairwise divergence). The male and female sequenced differ by 0.5% (Supplementary Table 1).
