Orchestomerus new species

Further update: We've dissected males of the south Texas Orchestomerus wickhami and more northern specimens and they are different species. Turns out the more northern ones are a new species associated with Parthenocissus (Virginia Creeper) and the southern are O. wickhami and associated with Cissus.

Moved

Moved from Orchestomerus.
Bob Anderson says: "Specimens are here and in my opinion you are correct and these are Orchestomerus wickhami and this would indicate wickhami has a much larger range than we suspected… but it’s not surprising."
I'll upload non-teneral pics eventually--all three specimens had the dark cross on the elytra that wickhami is supposed to, and in the original description that was a main distinguishing feature from ulkei.
Based on this, I wonder if this is also really wickhami:
