Cerconychia Klapálek, 1913 View in CoL

Cerconychia View in CoL was proposed by Klapálek (1913) for C. brunnea View in CoL and C. livida View in CoL , a closely related pair of Taiwanese species. These remained poorly known until Uchida & Isobe (1989) designated male lectotypes and provided comprehensive redescriptions for both species. Included in the Uchida & Isobe (1989) study was the first nymphal description for a species placed in the Styloperlidae View in CoL . The genus, as currently defined, is distinguished from Styloperla View in CoL on the basis of a transversely oriented hair brush on male sternum 9, the absence of vaginal sclerites, and a parabolic, lightly sclerotized projection on the apex of male tergum 10. The latter structure is considered a rudimentary epiproct and is flanked basally by a pair of rudimentary hemiterga ( Uchida & Isobe 1989). In addition to the Taiwanese species, Yang & Yang (1995) described C. sinensis View in CoL from a small sample collected at Jianfengling on Hainan Island
