Neoperla perspicillata Zwick View in CoL
( Figs. 4–6 View FIGURE 4 View FIGURE 5 View FIGURE 6 )
Redescription. Adult habitus. ( Fig. 4 View FIGURE 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 View FIGURE 4 ); compound eyes blackish, antenna yellow except terminal segments brown ( Fig. 4c View FIGURE 4 ); palpi brown. Pronotum black, lateral margins lighter, with rugosities and strip-like midline ( Fig. 4a View FIGURE 4 ); wings subhyaline, veins dark brown; legs black, basal part of femur yellow, the yellow bands wider in mid- and hindlegs ( Fig. 4c View FIGURE 4 ). Cercus black, basal segments yellowishbrown ( Fig. 4b View FIGURE 4 ).
Male. ( Figs. 4–6 View FIGURE 4 View FIGURE 5 View FIGURE 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 View FIGURE 4 ). Tergum 8 medially with a large trapezoid sclerite covered with several median spines ( Fig. 4b View FIGURE 4 ). 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 & 4d View FIGURE 4 ). Aedeagal tube nearly straight, dorsal surface with two contiguous patches of tiny spines medially ( Figs. 5b & 5d View FIGURE 5 ). Apex of aedeagal sac with a ventral patch and two lateral patches of larger spines ( Figs. 6a & 6b View FIGURE 6 ); lateral surface of sac with a long and large patch of numerous small spines at subapcial region ( Fig. 6b View FIGURE 6 ).
Examined Material. 3 males ( HIST), China: Tibet, Motuo, Beibeng , 2017. VI. 9, 930m, 29°14’57’’ N, 93°11’35’’E, Yang Qicheng GoogleMaps .
Distribution. China (Tibet), India, Nepal.
Diagnosis and remarks. Our specimens agree well with descriptions and illustrations of N. perspicillata Zwick, 1980 , even details of aedeagal tube is identical (comparing Figs. 5c, 5d View FIGURE 5 and figs. 26c, 26d, Zwick & Sivec 1980). Aedeagal sac is same as the redescription of N. perspicillata Zwick (comparing Fig. 6 View FIGURE 6 and fig. 2, Li et al. 2019). Although specimens have concave pigment in the dark center of head which is different from the redescription by Li & Liu, the intensity and extent of the head pattern is variable in type series of N. perspicillata . So we think these specimens belong to N. perspicillata Zwick.
