Moved from Nitidulid series.

Andrew Cline replies, "Interesting... definitely not a Kateretid. Looks more like a Carpophiline nitidulid ... I’m cc’ing Gareth Powell as he is the expert on the carpophilin-lineage."

Moved from Amartus tinctus.

James' concern is well-founded. I understand that Andrew Cline is an expert on this family, but he needs to take another look and explain his ID. Amartus has "Antennae with a loose, three segmented club and last segment subappendiculate" (1). Also, the pronotum is the wrong shape for A. tinuctus, being widest near the middle vs. near the base. None of the other Kateretidae genera appear to have such a compact spheroidal club (2). Many species in Nitidulidae do, though.

I don't think this can be Amartus tinctus?
Look at the antennae and shape differences compared to the others here.
