Chalepus bicolor (Olivier), male
Moved from Anisostena ariadne. ID'd from specimen, now a photo-voucher. Thanks Lisa.

While superficially similar to some species of Anisostena, this guy lacks the noticeably bowed middle tibiae (although the dorsal photo here seems to suggest it is bowed). It is also larger in size than most Anisostena.

Chalepus bicolor usually has black spots on the pronotum, but sometimes is completely red like this specimen. They usually also have the base of the femora reddish.

Moved tentatively
Based on the description in Staines (2006) and geographic distribution, this is the best fit. It lacks the longitudinal basal groove on the pronotum (as seen in A. lecontei) and the pronotum looks too densely punctate for A. kansana. Still, I cannot complete rule-out the latter.

Staines (2006) did not record it from KY, but it's in many surrounding states (MO, TN, GA, VA, others...)

Moved from Beetles.
