Note: This species was first recorded from Taiwan by CAMERON (1949) under the name " S. verecundus SHARP " from "Musha (= Nantou: Wushe). Most of the Taiwanese specimens have comparatively large (broad) elytra. First I thought, that this may be an indication for a separate subspecies. But measurements of some hundreds of specimens from Taiwan and from the mainland of China led to the result, that the Taiwanese specimens fit in the variability range of the nominate species.
