Three new species of Cryptocercus Scudder, 1862 are described: C. hirtus Grandcolas & Bellés n. sp., C. meridianus Grandcolas & Legendre n. sp. and C. parvus Grandcolas & Park n. sp. They extend the distribution of the genus to the South and to the North in China. As expected, these new data show that the genus is distributed in varied regions with classical distributional trade-offs between altitude and latitude. These new species together with C. relictus Bey-Bienko, 1935, C. primarius Bey-Bienko, 1938, C. matilei Grandcolas 2000, and C. kyebangensis Grandcolas, 2001, bring the number of East Asian species in the genus to seven. Morphological features of these species, including spine numbers on femora, pronotum shape, and genitalia structure, show a wide range of variation among species, larger indeed than among North American species.
