Largusoperla crassus Chen, 2018c

Largusoperla crassus Chen 2018c . Zootaxa, 4462(2): 296. Specimen status: male holotype, CZT-PLE-MA5 (ICJUST).

Remarks. Largusoperla crassus can be distinguished from other congeners by the paraprocts asymmetrical, subtriangular and slightly upcurved, apparently mostly sclerotized except for the paler bases; left paraproct narrow,

right paraproct expanded, apex blunt, subapically with several creases (Fig. 1, Figs. 2 D-E). This species is the only currently described Largusoperla species with well-visible tergal structures.
