Revision of the Therates tuberosus group (Coleoptera: Cicindelidae)

The known species of the tuberosus group of the genus Therates Latreille (Coleoptera: Cicindelidae) are redescribed. Therates rugosoangustoides Wiesner and Anichtchenko, new species, is described from northern Vietnam while T. horni Wiesner, 1988, new status, and T. pseudotuberosus Wiesner, 1988, new status, are elevated to species rank. Identification keys for the twelve groups of the genus Therates and for the eight species of the tuberosus group are provided. Lectotypes are designated for Therates tuberosus Fleutiaux, 1893, Therates angustatus Horn, 1902, Therates crebrepunctatus Horn, 1923, and Therates rugosoangustus Horn, 1929, to stabilize their nomenclature to single specimens.
