This spec. is Polyzonus (Chelidonium) siamense Podany, 1974.
In Bentanachs, 2012 as n. syn. of Polyzonus prasinus White, 1853.
P. prasinus is, after my experience, endemic to south India. P. siamense is widespread and common in China, Myanmar, Laos, Thailand and Vietnam.
Distinct morphological differences in length and width of the antennae and other things. The genital morphology is in this species very distinctive.
Another spec. of this group is known from Malaysia pen., might be new or described in Stenochroma.
A publication on this problem is in work.
