Moved from Berosus.

Looks like B. moerens Sharp, as illustrated in Van Tassell (1963). I haven't dug into the Berosus literature for quite some time, so I'm not sure whether that's a good name or not. There is a key in the paper below with illustrations for several related species.

B. moerens Sharp is still valid
Will look into the paper when dust settles. Thanks much!

Neat beetle
Neat beetle, whether it is that species or another. When I first saw the photo, I was hoping it might be Hemiosus, as I've yet to see one of those. I've done a lot of dip-netting in Cochise County, but not in Santa Cruz Co. I've always meant to check out Pena Blanca Lake. I may be down that way next month, so maybe I'll try my luck.

If you need a PDF of the Van Tassel paper, let me know.
