description: <i>Phanoperla wangi</i> Wang, Li &amp; Li, sp. nov. (Figs. 1–2) <b>Male</b>. Forewing length 10.2 mm. General body color light brown. Biocellate, ocelli brown, surrounded by black rings, ocelli nearly touching (Fig. 1a). Head pale, with a small brownish triangular marking forward of pale M-line; compound eyes large and black; antennae pale brown (Fig. 1a). Pronotum with well-delimited darker rugosities on pale disc, anterior and posterior margins dark brown, lateral margins pale with rounded corners (Fig. 1a); wing membrane pale, veins dark brown, Rs with two branches; femur pale brown, tibia brown. Abdominal segments generally pale brown. <i>Terminalia</i>. Sternum VI with weak setae and sternum VII with brushes of strong setae (Fig. 1c). Tergum IX with two large, separated patches of short setae beneath the tip of hemitergal processes, and several setae in medial shallow depression (Figs. 1b, d). Hemitergal processes of tergum X strongly sclerotized, its sharp tip curved outward, and stout basally (Fig. 1b). Aedeagal tube straight, boundary of dorsal sclerite unclear, covered by multiple rows of small spicules; ventral side of tube ending in a large subcordate protuberance covered with small distally spicules, apicolateral lobe curved dorsad and bald (Figs. 2a–b, d). Everted sac long and curved ventrad against protuberance covered with fine spicules, tubular apex of aedeagus with 5 irregular rows of ca. 30 strong hooks basally and fine small spicules distally (Figs. 2c–e). <b>Female</b>. Unknown. <b>Type material.</b> Holotype: male (CAUC), China: Yunnan Province, Dehong Dai and Jingpo Autonomous Prefecture, Yingjiang County, Tongbiguan Village, N24.6113°, E97.6569°, 1135m, 2017.V.29, Liang Wang leg., light trap. <b>Etymology</b>. The species is named after Dr. Liang Wang, collector of the holotype. <b>Distribution</b>. China (Yunnan). <b>Diagnosis and remarks</b>. The male of new species is characterized by the irregular hooks of tubular apex in aedeagal sac on the dorsal side. The new species is a typical member of <i>Phanoperla maindroni</i> group sensu Zwick (1982) by the enlarged ventrodistal protuberance on the apex of the aedeagal tube, which is against the recurved sac, and is closely related to <i>P. maindroni</i> Zwick, 1982 known from India by sharing nearly identical outline of aedeagus. However, their aedeagus are different dramatically. In <i>P. wangi</i> <b>sp. nov.</b>, the apical protuberance of aedeagal tube bilobed but that in <i>P. maindroni</i> is entire; tubular apex of <i>P. wangi</i> has 5 irregular rows of strong hooks basally whereas the hooks of <i>P. maindroni</i> present before the tubular apex (Fig. 7b).
