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.
