Abstract
The cockroach genus Eucorydia from China is revised. Five new species are described and illustrated: Eucorydia linglongsp. n., Eucorydia pilosasp. n., Eucorydia splendidasp. n., Eucorydia guilinensissp. n., and Eucorydia tangisp. n.. Corydia purpuralis Kirby, 1903 and Eucorydia paucipilosa Woo, Guo & Feng, 1986 are confirmed to be junior synonyms of Eucorydia dasytoides (Walker, 1868). Eucorydia hilaris (Kirby, 1903) is newly recorded from China. This genus and currently known species from around the world are discussed. The status of Eucorydia maxwelli (Hanitsch, 1915) is revived. Corydia plagiata Walker, 1868 is confirmed to be a junior synonym of Eucorydia ornata (Saussure, 1864). A checklist, key, and photographs of members of this genus are provided.
