[Community] Cordulegaster wings pattern

[bernhard_renaud at bluewin.ch]

Good morning,

I'm studying the Needham's system for Odonata wings pattern.
There is something that is unclear for me at this point about the Cordulegaster genus' veins.
There is that distinctive vein (in sky blue on my graphic) that runs to the hind border of the wing

It is starting from the 
Bridge vein (in brown). Is it still considered as the Supplementary Radial Vein (Rspl) althou it doesn't start from the 
Radial vein (in Red) like it is on other genus (to my knowledge)?



Thanks in advance and Merry Christmas!
