Treatment

Suarius fangwengi sp. nov.

( Figs. 1F View FIGURE 1 , 6–7 View FIGURE 6 View FIGURE 7 )

Diagnosis. Medium sized. Body mostly brown. Head with markings on gena, anterior tentorial pit, near compound eyes, middle frons, vertex and occiput; antenna yellowish, diagonal irregular stripes present on front scape. Forewing veins brown at intersections; pigmented pterostigma present, with brown markings; hindwing with brown markings on pterostigma and dcc cell.

There are 17 Suarius species from the Palaearctic region bordering or nearing Xinjiang, including Mongolia, Kyrgyzstan, Afghanistan, Kazakhstan ( Oswald, 2024). Four of the above species are distributed in Xinjiang: S. gobiensis , S. mongolicus , S. trilienatus , and S. yasumatsui ( Yang &Yang 2005) .This new species can be distinguished from all the other species by the markings on front scape, and the brown markings on veins.

Description. Body mostly brown. 7.01–8.78 mm long ( Fig. 6A–B, E View FIGURE 6 ).

Head. 1.30 mm wide (including compound eyes). Mostly yellowish, with brown genal markings, brown anterior tentorial pit markings present; small brown lateral clypeus markings connected to compound eyes present; a pair of dark brown curved transverse stripes present on frons, and connected at middle; a pair of brown markings present at basal antenna; a pair of longitudinal brown stripes present on occiput. Mandibles asymmetrical, broad; labial palpus brownish, but palpomere 3 black, tapered apically; maxillary palpus brownish, black at palpomeres 3 and 5, pale at joints, tapered apically.Antenna shorter than forewing, yellowish, scape yellowish, diagonal irregular stripes present on front scape; pedicel yellowish, slightly brown anteriorly, flagellar setae arranged in four rings, flagellum yellowish, setae yellowish ( Fig. 6A–E View FIGURE 6 ).

Thorax. Yellowish, pronotum about 0.8 times as long as wide; setae dark, with brown, broad stripes laterally, and dark brown lines on median portion of pronotum; meso- and metanotum with brown, broad stripes laterally ( Fig. 6A–B, D–E View FIGURE 6 ).

Legs. Yellowish, with dark, long setae. Femora with dark brown ring-shaped markings, on foreleg: medially, about 0.5 times as long as femur; midleg: distally, about 0.2 times as long as femur; hindleg: distally, about 0.5 times as long as femur. Claws curved, brown (Fig, 6E).

Forewing. 9.56–10.00 mm long. Wing membrane transparent, rounded apically, tegula brownish; pterostigma brown; longitudinal veins pale with large dark markings at intersections of veinlets, radius posterior pale with large dark marks at each intersections of veinlets: crossveins dark brown, radial crossveins 1–4 pale at middle; 1st, 4th psm-psc crossveins pale at middle; irregular brown markings present on following veins: distal radial crossveins, distal MP (media posterior), intersections of veinlets of RP (radius posterior), gradate crossveins; 2nd, 3rd, 5th, 6th psm-psc crossveins; dcc cell. Costal crossveins simple, straight, 16 costal crossveins present, 6 crossveins posterior pterostigma, 9 radial crossveins present; im triangular, subdistally connected by 1st rp-m crossveins; two gradates series of crossveins present, number of gradates crossveins (inner/outer): 3/4; basal crossveins of first gradate series not meeting PsM; dcc open; CuP not forked ( Fig. 6A View FIGURE 6 ).

Hindwing. Pterostigma and distal dcc with irregular brown markings, most longitudinal and crossveins pale with large dark markings at intersections of veinlets; costal crossveins brown, 1, 5–9 radial crossveins brown, gradate crossveins brown; two gradates series of crossveins present, number of gradates crossveins (inner/outer): 4/4 ( Fig. 6A View FIGURE 6 ).

Abdomen. Mostly brown; yellowish markings present on terga; spiracles small, round, not enlarged, atria not enlarged ( Fig. 6A, E View FIGURE 6 ).

Male genitalia. Tergum 9 and ectoprocrts fused; ectoproct rounded; dorsal invagination shallow; thick setae on ectoproct absent; sterna 8 and 9 fused, regular, without strong apical setae; gonarcus medially fused, lateral arm expanded; mediuncus associated with gonarcus, slender, curved, bifurcated and expanded apically; gonocornua present, about 0.4 times as long as mediuncus, tapered apically; entoprosesscus long, enlarged at middle; mediuncus process absent; hypandrium V-shaped in lateral view, with expansion; parameres absent; gonosetae sparsely present; tignum absent; microtholi absent ( Fig.7A–E View FIGURE 7 ).

Female genitalia. Unknown.

Type material. Holotype ♂, CHINA, Xinjiang, Bayingolin, Luntai ( Ë台), 41.4365°N, 84.2960°E, 942.0 m, 22.VII.2022 (L), Yuchen Zhao ( CAU) GoogleMaps . Paratypes: 1♂, same data as holotype GoogleMaps ; 1♂, CHINA, Xinjiang, Turpan, Shanshan, Hongyuanzi ( IJKŦ), 43.1725°N, 90.1541°E, 1006.0 m, 22.VII.2023 (L), Zhichao Zhou, Zijun Liu, Huaiyu Liu ( CAU) GoogleMaps .

Etymology. The specific name is to honor the great patriot and poet, Lu You ( Ŀĸ) as he sobriquet himself “Fang Weng ( ẍä)”, in Song Dynasty of ancient China, and the famous poem he composed, in which the type locality Luntai was mentioned.

Distribution. China ( Xinjiang).

Remarks. S. fangwengi sp. nov. was founded in Tuha Basin and northern Tarim Basin, both characterized by arid habitats. It is likely associated with semi-desert margins, similar to the habitats of other Suarius species ( Tauber 1975; Letardi et al. 2020).
