description: <i>Neoperla perspicillata</i> Zwick (Figs. 4–6) <b>Redescription. Adult habitus.</b> (Fig. 4) Distance between ocelli wider than diameter of one ocellus. Head slightly wider than pronotum, reddish brown forward of M-line, and black posterior to M-line (Fig. 4a); compound eyes blackish, antenna yellow except terminal segments brown (Fig. 4c); palpi brown. Pronotum black, lateral margins lighter, with rugosities and strip-like midline (Fig. 4a); wings subhyaline, veins dark brown; legs black, basal part of femur yellow, the yellow bands wider in mid- and hindlegs (Fig. 4c). Cercus black, basal segments yellowishbrown (Fig. 4b). <b>Male.</b> (Figs. 4–6) Forewing length 11.8 mm, hindwing length 9.2 mm. Process of tergum 7 sclerotized, triangular with nipple-like apex, covered with small sensilla basiconica (Fig. 4b). Tergum 8 medially with a large trapezoid sclerite covered with several median spines (Fig. 4b). Tergum 9 with two separated mesal humps covered by sensilla basiconica and hairs. Hemitergal process of tergum 10 finger-like, slightly curved medially in dorsal view but nearly straight in lateral view (Figs. 4b &amp; 4d). Aedeagal tube nearly straight, dorsal surface with two contiguous patches of tiny spines medially (Figs. 5b &amp; 5d). Apex of aedeagal sac with a ventral patch and two lateral patches of larger spines (Figs. 6a &amp; 6b); lateral surface of sac with a long and large patch of numerous small spines at subapcial region (Fig. 6b). <b>Examined Material.</b> 3 males (HIST), China: Tibet, Motuo, Beibeng, 2017. VI. 9, 930m, 29°14’57’’ N, 93°11’35’’E, Yang Qicheng. <b>Distribution</b>. China (Tibet), India, Nepal. <b>Diagnosis and remarks</b>. Our specimens agree well with descriptions and illustrations of <i>N. perspicillata</i> Zwick, 1980, even details of aedeagal tube is identical (comparing Figs. 5c, 5d and figs. 26c, 26d, Zwick &amp; Sivec 1980). Aedeagal sac is same as the redescription of <i>N. perspicillata</i> Zwick (comparing Fig. 6 and fig. 2, Li <i>et al.</i> 2019). Although specimens have concave pigment in the dark center of head which is different from the redescription by Li &amp; Liu, the intensity and extent of the head pattern is variable in type series of <i>N. perspicillata</i>. So we think these specimens belong to <i>N. perspicillata</i> Zwick.
