Abstract

The nymphs of Chankagenesia yangi (Hsu, 1936) are described for the first time and selected key structures of adults are clarified. Compared to the valid congener C. natans Buldovsky, the nymphs of C. yangi have spines on lateral large projections of frons and more in between them. In the same structure of adults, the lateral projections of C. yangi are smaller and blunter. The nymphs described here confirm the status of the species and show that the genus has a vast distribution.
