B.A. Korotyaev & J.Ye. Meleshko
Abstract. Tylodrusus Stierlin, 1884 is paced in synonymy with Eustolus Thomson, 1859, and Chaerodrosus Reitter, 1916 with Metadrosus Schilsky, 1910. New subgenera are established: Poecilodrusus (type species P. viridicinctus Gyll.), Scythodrusus (type species P. inustus Germ.), Orodrusus (type species P. obliquatus Fst.) and Eurodrusus (type species P. confluens Steph.). The subgenus Caenotylodrosus Kono & Morimoto, 1960 is redescribed. Polydrusus (Metadrosus) svetlanae sp. n. from Uzbekistan and P. (Caenotylodrosus) sichuanicus sp. n. from China are described.
