About this book

Contains two articles.

The Liatongus Species with Moveable Clypeal Horn (Coleoptera: Scarabaeidae)
Currently the genus Liatongus Reitter, 1892 contains the following five species with moveable clypeal horn: L. ancorifer sp. n. (China: Yunnan prov.), L. appositicornis sp. n. (China: Gansu prov.), L. clypeocornis Scheuern, 1988 (Bhutan), L. hastatus sp. n. (Nepal) and L. triacanthus (Bouccommon, 1920) (Sikkim, Darjeeling; first record for China: Xizang here given). Diagnostic characters including parameres of the three newly described species are illustrated. The female of L. triacanthus is described for the first time. A table with characters separating Liatongus species with a moveable clypeal horn from each other is given. The taxonomic position of the species closely related to L. triacanthus, distinctive defensive behaviour and potential necrophagy are discussed.
