Revision of the Tribe Hydarini in the Oriental region (Hemiptera, Heteroptera: Coreidae).

The tribe Hydarini Stal (Coreidae) from the Oriental region is revised: seven species in four genera are recognized, of which Hydarella chiangdaoensis from Thailand and Laos and H. sundae from the Lesser Sunda Islands are newly described. A key to the known taxa is given and new records are added which extend the distributional range of the Hydarini from China in the north to the Lesser Sunda Islands in the south
