Key to species of Tapiena (for males only)
Tapiena emarginata Karny, 1923 , Tapiena latifolia Ingrisch & Shishodia, 2000 , Tapiena pentagona Karny, 1923 and Tapiena triangulata Karny, 1926 are only known for females and thus not included in this key. This key is modified from key for China species by Liu & Kang (2010).
