Zygoneura (Pharetratula) occidens Zhang & Wu, 2010 View in CoL [ Zhang et al. (2010): 45 View Cited Treatment ; Shin et al. (2014): 562; Huang et al. (2020): 361].

Type locality. China: Sichuan Province, Yaan .

Type Material. Holotype (1♂) in Coll. ZAFU ( China).

Material examined. Holotype [ SM00946 ], 1♂, Sichuan province, Yaan, Labahe , 1200m, 29°59′ N, 102°59′ E, 16.VII.2006, leg. Xiao-Ling Niu. GoogleMaps

Additional description. Male. Head brown, antenna and maxillary palpus yellowish brown. Eye bridge four facets wide. Face with 7–8 setae. Maxillary palpus with three segments ( Fig. 14B View FIGURE 14 ). Fourth antennal flagellomere 3.5 times as long as wide, body with long subequal setae ( Fig. 14D View FIGURE 14 ). Thorax brown. Wing membrane without macrotrichia ( Zhang et al. 2010: 46, Fig. 3D View FIGURE 3 ), anterior veins slightly darker than posterior veins. M 1, M 2, CuA 1, CuA 2, r-m with no setae. stM faintly visible in the specimen. Legs ( Fig. 14A View FIGURE 14 ) yellowish. Tarsal claws three-toothed. Hypopygium ( Fig. 14C View FIGURE 14 ) yellowish brown. Gonocoxae longer than gonostyli, ventral medial margin with two weakly visible groups of setae. Gonostylus ( Fig. 14C View FIGURE 14 ) somewhat oval, with three megasetae at the apical third. Tegmen membranous, wider than high. Aedeagus long and slender ( Fig. 14C View FIGURE 14 ). For detailed description, see Zhang et al. (2010).

Remarks. Only holotype seen, 1♂ paratype [SM00947] is lost. This species resembles Z. (Zygoneura) sciarina Meigen in the gonostylus with three megasetae. However, it can easily be diagnosed by the oval shape gonostylus, and the position of the three megasetae is completely different as compared to the latter species ( Fig. 14C View FIGURE 14 ).

Distribution. China: Sichuan, Xizang ( Zhang et al. 2010).
