Abstract
The genus Tapiena (Orthoptera: Phaneropteridae: Phaneropterinae), consisting of species from around Asia and Africa, is reviewed. Henningian species concept was applied and morphology was used to estimate species boundaries. From Sakaerat Environmental Research Station, Thailand, two new species are described: Tapiena sakaerat Tan, Liu, Artchawakom sp. n. and Tapiena denticulata Tan, Liu, Artchawakom sp. n. This represents the first record of the genus Tapiena in Thailand. A key to the species of Tapiena (for males only) is also provided.
