Keys to Sepidophilus opicus in Campbell (1976). Looks like a female, and the 8th tergite segments are a perfect match to figure 59.
Confirmation/correction appreciated.

I initially agree with opicus
I initially agree with opicus, but now I kind of doubt what I was seeing. I recently revised some of my material, and those I IDed as opicus have a slightly different habitus: https://www.inaturalist.org/observations/169936904

I would have called yours Sep. basalis, as the basal band of the elytra are not widely connected. Now your 8th tergite does really fit better with opicus, so I'm not sure either! I have added a picture of my Sep. basalis on Bugguide (dissected male) if it can help
