New records of powder-post beetles (Coleoptera, Bostrichidae) from China

The Bostrichidae is a small family of Coleoptera, with up to 600 described species all over the world. Almost 90 species of the family have been recorded in China at present and several new species of powder-post beetles have been described in recent years. Since the 1940s, the family Bostrichidae has become a neglected group in the taxonomy research of the Chinese mainland compared with its extensive territorial and super complex ecological diversity. Thus, there is need for more field specimen collection and in-depth taxonomic study.In this study, two powder-post beetles species Trogoxylon spinifrons (Lesne, 1910) and Minthea bivestita Lesne, 1937, are recorded for the first time from China. New provincial distribution records of another 18 Bostrichidae also listed.
