摘要

A new species of the subgenus Haplothemus Wittmer, 1973 of the genus Themus Motschulsky, 1858 is described: T. (H.) fissus sp. n. (China: Yunnan; Myanmar: Kachin). Themus (H.) particularis Pic, 1929 is redescribed and re-assigned from the nominotypical subgenus Themus to the subgenus Haplothemus. Its distribution is verified to be confined to Vietnam and, therefore, it has been excluded from the Chinese fauna. The descriptions presented are complemented with photos of habitus and female genitalia and illustrations of aedeagus and female abdominal sternites VIII.
