Abstract
The genus Cryptopenella is treated as a subgenus of Choroterpes. Unlike Choroterpes (Euthraulus), the expanded styliger plate of the male of C. (Cryptopenella) covers the penes. However, the nymphs of C. (Cryptopenella) resemble those of C. (Euthraulus). This subgenus includes Choroterpes (Cryptopenella) facialis Gillies, C. (Cryptopenella) anhuiensis Wu & You and C. (Cryptopenella) tumebasalis, sp. nov. described from male and female imagos and nymphs from Yunnan Province, China. The Taiwanese species, Choroterpes trifurcatà Uéno (belonging to the subgenus Euthraulus), is treated as a different species from C. (Cryptopenella) facialis (Gillies).
