I give up on differentiating D. constricta from D. antica. Initially thought D. constricta, but looking at images of D. antica, this seems to qualify. I'm still not entirely sure what constitutes "downturned". Also, I believe the blue appearance of the venation is due to chromatic aberration from the brightness (could be wrong).
