Leaf-mining ceutorhynchine - Orchestomerus eisemani

Leaf-mining ceutorhynchine - Orchestomerus eisemani
Bridgewater, Plymouth County, Massachusetts, USA
August 31, 2013
Size: 2 mm
I've just reared two of these weevils from leaf mines collected two weeks ago. If the species can't be determined conclusively from these photos, to whom should I send the specimens?

Added 12/28/2015: this beetle is either the holotype or one of the paratypes of Orchestomerus eisemani.

Moved from Orchestomerus wickhami.
Bob has revised his determination, based on dissection & comparison with the type.

 
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 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:

 
terrific; thanks, Kollegen!

Moved tentatively; looks teneral... what about host plant?
Moved from Snout and Bark Beetles.

i suspect Brad Barnd could handle the voucher specimen
