Moved from Dineutus.

ID: Dineutus discolor
Based on the lightly colored venter, narrowly elongate oval body form, and elytral apices, this is Dineutus discolor.

Not Dineutus americanus
Much too large to be D. americanus, but also distribution precludes. See Epler's Florida beetle manual (http://bugguide.net/node/view/50813) for a discussion on the confusion surrounding this name. I'm having trouble seeing characters (elytra apex and the aedeagus, which is only barely visible in the ventral shot) but I'm leaning towards saying Dineutus nigrior since the protibia seems to be produced and not rounded.
