Vietnam, Dong Bac, Ha Giang, VI.2013
22 mm

Polyzonus prasinus, sinensis, yunnanus, Parapolyzonus???
Bentanachs' keys seems confusing enough...

That is a spec. of the Chelidonium argentatum group.
This group is clearly different in the genital morphology !
Beside many other spec. of Chelidonium, Stenochroma punctigera Pascoe, 1869 is also a member of this group !
A group with very difficult spec.
Among the green species I have more than 6 spec. with nearly the same morphology. One spec. gives in totally green or like venereum with yellow spots !!!
Constant differences only in the genital morphology.
