Distribution.

China (Jiangxi, Fujian, Guangdong, Yunnan, Guangxi, Hainan, Taiwan).

Remarks.

These are new province records to Fujian, Guangdong, Yunnan, Guangxi, Hainan. Specimens from Hainan (Figs 24, 25) have smaller black marks, especially on the ventral side and legs, the second inner black spot is absent in approximately half of the specimens. However, no differences are found in sexual characters, suggesting that the Hainan population may represent a new subspecies. The species is very similar to Scaphidium baconi Pic, 1915 (see Pic 1915b) distributed in Nepal, India, Thailand, and Vietnam. Reliable distinguishing characters between them are unknown, and the validity of Scaphidium baconi is suspicious. The species is also similar to Scaphidium carinense Achard; for differences see remarks below.
