Remarks. This species has a bifurcated ventral plate like its sibling, Mimela semirubra new species. The specimens from Hainan possess shorter branches compared to most of the mainland individuals (except for a specimen from Zhejiang). No evident morphology differences could be concluded from the insular population, apart from the ventral plate. Therefore the material examined here is considered to be monospecific. This species is recorded from Laos for the first time.

Distribution. China: Fujian, Guangdong, Guangxi, Hainan, Hunan, Jiangxi, Yunnan, Zhejiang *; Laos *: Xieng Khouang; Vietnam: Bac Giang.
