I think...
this might be misplaced. It looks more like the dark form of Eugnamptus angustatus.

Thank you.
You are most likely correct as I can't tell the difference.
I'd appreciate it if you would point out what to look for to differentiate?
Thanks.

Okay
A couple things are the shape of the elytra, yours being clearly parallel sided and elongate, while Apionines are short and rounded (giving the common name pear-shaped). The vestiture of yours is long hairs, while I. virens are more appressed, less abundant and somewhat scale-like. Third, and perhaps the most obvious if you still can't differentiate, are the antennae. The last three segments of yours are long, enough to not appear club-like and are straight. I. virens has a typical weevil antenna with an elbow and a definite club.

Hope that helps!

Thank you very much.
