Actually, I shouldn't have said "Scarabaeoidea"--as the striae/puncture pattern does look a fair bit like those of some Platycerus, e.g. marginalis or cribripennis.

  Subject: Pleistocene scarab fragments?

  Hi all,


  I am a little bit lost, so it's time to ask the list, I guess.

  I am working on scarab fragments of a Pleistocene site of Colorado. Most of them are Aphodius heads (or Aphodius s.l. heads, for the splitters). I also got a few elytral fragments with a pretty distinct sculpture, consisting of broad deep, largely punctured stripes and not much broader, elevated, equally largely punctured intervals (see attached photo).

  I thought I have seen such elytra before, but cannot remember. I got them as possible scarabs, but I am struggling to find a North American scarab with such elytra. Could it be something else? I cc to Mike Ivie because he knows all those little families that nobody else knows (or are you on the Scarbs-L list, Mike?).

  Any ideas? Thanks!
