DISTRIBUTION AND VARIABILITY OF PLASTOCERUS THORACICUS FLEUTIAUX, 1918 FROM CHINA (COLEOPTERA: ELATERIDAE: PLASTOCERINI)

Plastocerus thoracicus Fleutiaux, 1918 was originally described from Vietnam and later reported from Guangxi and Yunnan Provinces of China. Here, we examined four specimens and provided the first records for Henan, Jiangxi, and Hong Kong. We confirmed this species is variable in the shape of the pronotum, and we also report and illustrate variability in the male pregenital segments and aedeagus. Additionally, we provide an updated distribution map for P. thoracicus.
