Revision of Eucorydia Hebard, 1929 from China, with notes on the genus and species worldwide (Blattodea, Corydioidea, Corydiidae)

The cockroach genus Eucorydia from China is revised. Five new species are described and illustrated: Eucorydia linglong sp. n., Eucorydia pilosa sp. n., Eucorydia splendida sp. n., Eucorydia guilinensis sp. n., and Eucorydia tangi sp. 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
