Asian species of the little-known subgenus Lagria (Lagriella) (Coleoptera, Tenebrionidae, Lagriinae), with a new species and the first record from China

The little-known subgenus Lagria (Lagriella) Borchmann, 1916 is characterized by pronounced sexual dimorphism, notably manifested in apterous females. In this paper, the Asian species of Lagria (Lagriella) are reviewed, including three known species, Lagria (Lagriella) bimarginata Fairmaire, 1896, L. (Lagriella) andrewesi Borchmann, 1916, L. (Lagriella) mima Borchmann, 1916, and the newly described L. (Lagriella) cordata<b>sp. nov.</b> from Guangxi, Guizhou, Hong Kong, Hunan, China. The new species represents the first record of the subgenus in China. Lectotypes are designated for L. (Lagriella) andrewesi and L. (Lagriella) mima. Habitus images, key diagnostic characters, ecological habitats of the new species, and type habitus of three known Asian species are documented. An identification key to the four Asian species is also provided.
