Peter, thanks for the explanation about this teneral beetle and its close appearance to C. rufa.

Clivina americana
based on my microscopic examination of this specimen which is deposited in the P.W. Messer collection as a photo-voucher. Thanks Tom.

NB: This lighter colored teneral (immature) stage of C. americana might be confused with uniformly reddish-yellow C. rufa. Immature americana usually has elytra with strial punctures finer and tend to fade more before apex. It also helps/biases the determiner that this specimen was captured very close in time & space with a typical dark americana posted here.
