Dear Chris, why is this a Grypoctonus sp.? I miss the second crossvein, has something changed in the description of the genus? Or is it simply absent in the left wing and present in the right wing?
Indeed it looks like the crossvein is missing. I've never actually used that character as the gestalt is recognizable enough. If this is Cyrtopogon, then Grypoctonus is not a valid genus IMO.
