Sphindus trinifer Casey
Voucher specimen, thanks Tom.

My comments from the iNaturalist post:
On your last specimen (https://bugguide.net/node/view/2382762) I noted my confusion over the separation of this species from "Sphindus americanus". After looking at my small collection of 8 specimens, I think this individual and one you previously sent to me (https://bugguide.net/node/view/948302) are S. trinifer. They have very large eyes compared to the other specimens, as well as a larger 8th antennomere which can clearly be considered part of a 3-segmented club.

My other specimens, which I am considering S. americanus, have relatively smaller eyes and a smaller 8th antennal segment, though the latter seems to vary a bit in size.
