Largusoperla dewalti Chen, 2018b

Largusoperla dewalti Chen 2018b . Zootaxa, 4450(4): 496. Specimen status: male holotype, CZT-PLE-MA3 (ICJUST).

Remarks. Largusoperla dewalti also has asymmetrical paraprocts ( Fig. 1 , Fig. 2B ), which were incorrectly drawn in Fig. 4 of Chen (2018b). The left paraproct is apparently longer than its right paraproct. It can be distinguished from congeners by the paraprocts very thick, hairy, finger-shaped, unevenly sclerotized with a banded pattern, apex rounded ( Fig. 2B ).
