Zygoneura (Pharetratula) disparilis Zhang & Wu, 2010 [Zhang et al. (2010): 43; Shin et al. (2014): 562; Huang et al. (2020): 360].

Type locality. China: Yunnan Province, Yingjiang .

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

Material examined. Holotype [SM00789], 1♂, Yunnan Province, Yingjiang, Tongbiguan nature reserve, 24°37.667′ N, 97°37.893′ E, 1513 m a.s.l. 16.V.2009, leg. Su-Jiong Zhang.

Additional description. Male. Head dark brown, antenna and maxillary palpus yellowish. Eye bridge three facets wide. Face with 5–6 setae. Maxillary palpus with three segments, 3rd segment long (Zhang et al. 2010: 42, Fig. 1B). Fourth antennal flagellomere 2.83 times as long as wide, with neck much longer, body with mostly short setae and with a row of distinctly elongated setae near the neck (Fig. 5C). Thorax light brown. Wing membrane without macrotrichia. M 1, M 2, CuA 1, CuA 2, r-m with no setae. stM faded in the specimen. Legs (Fig. 5A) stramineous. Tarsal claws three-toothed. Hypopygium (Fig. 5B) yellowish brown. Gonocoxae nearly as long as gonostyli, ventral medial margin with two distinct groups of setae. Gonostylus (Fig. 5B) stout, with two megasetae of unequal length overlap each other, apex attenuated, broadly round with numerous short setae. Tegmen membranous, higher than wide. Aedeagus short, slender (Zhang et al. 2010: 42, Fig. 1E). For detailed description, see Zhang et al. (2010).

Remarks. Only holotype seen, 1♂ paratype [SM00824] lost, 1♂ paratype [SM00919] on loan and not examined in this study. This species resembles Z. (Pharetratula) flavicornis (Mamaev) and Z. (Pharetratula) bidens (Mamaev) in having a pair of megasetae but can be recognized by the gonostylus attenuated at the apex, and two megasetae on a shorter dorsal lobe, of unequal length, overlap each other in ventral view (Fig. 5B).

Distribution. China: Yunnan (Zhang et al. 2010).
