A new species and a new record of Xistrella from China (Orthoptera: Tetrigidae)

The genus Xistrella Bolívar, 1909 (Orthoptera: Tetrigidae) is taxonomically reviewed. It can be easily recognised from other genera in SE Asia, and especially in the People’s Republic of China. It is distinctive by antennae inserted below the inferior margin of eye and considerably long; pronotum between the shoulders strongly elevated to obtuse gibbosity or slightly elevated in the posterior part of shoulders. This genus is distributed mainly in China, India, Indonesia, Sri Lanka, Myanmar, Nepal, Malaysia, and the Philippines. One new species, X. hainanensis Deng sp. nov. (China: Hainan), is described, and a new record of X. dubia (Brunner von Wattenwyl, 1893) from China is given. An annotated identification key to all species of the genus Xistrella is provided
