Two new species of Cryptoperla (Plecoptera: Peltoperlidae) from China, with description of the nymph of Cryptoperla dui Sivec

Abstract

Two species of the peltoperlid genus Cryptoperla Needham, C. dactylina Du, sp. nov. and C. nangongshana Huo Du, sp. nov. are described as new to science from Yunnan and Shaanxi provinces of China. Cryptoperla dactylina is characterized by a finger-like sclerotized projection with small-rounded processes on the first cercal segment and C. nangongshana is characterized by clusters of long bristles on the first six cercal segments. Additionally, a description of the nymph of C. dui Sivec is provided.

A new species of Cryptoperla Needham, 1909 (Plecoptera: Peltoperlidae) from Guangxi of China, based on male, female, and larval stage

“…No similar cerci or aedeagus were found after comparison with other Asian species (aedeagus of some Chinese species still unknown, e.g. even the lately described C. dactylina Du, 2018(in: Huo & Du 2018). The larva also appears similar to the C. pentagonalis by configuration of ventral fringes of thorax and dense blade-like setae of the cerci, but easy to distinguish on the basis of distinct color pattern.…”
