Hybosoridae - Germarostes globosus

Hybosoridae - Germarostes globosus
Middleburg, Clay County, Florida, USA
May 28, 2009
Size: 4.5mm
Collected under lights. The 4.5mm measurement is in the rolled up position, est ~6mm
unrolled! I picked Byrrhidae solely for the round pill form. Had trouble unrolling this
guy to find an 11 seg geniculate ant w/3seg club. Tarsi appears to be 5-5-5 w/simple claw.
Strong ridges @ posterior elytra. Straight elongated "dashed" punctation entire elytra.
All tibiae are broad and give a completly "armored" appearance when rolled up. Any ideas?

Germarostes
V: Thank you for the ID. But, could you please help me out. What gave
you the clues to look in Scarab's for a pill bug?. I didn't even get
the family correct, and after reviewing Woodruff's Scarab's of Fl, the
only "globosus" I could find were Cloeotus and Acanthocerus, both
probably Syn's of Germarostes I would guess. Arnett (Vol II, pgs
33-35) only lists two species under Hybosoridae, and Germarostes
is listed under Ceratocanthidae.

 
What gave me the clues...
I just knew the beetle... so i'd recognize it no matter how ball-rolled it might be, all the more so that no other beetle, be it a leiodine, a byrrhid, a lamprosomine, or a dorcatomine looks exactly this way. The first [and only] time i bumped into this beast alive, it took me a look at its head & antennae to recognize a lamellicorn (=scarabaeoid) beetle, and then to figure it out immediately from the only guide i had back then (White 1983). The classif.used here places ceratocanthids in Hybosoridae; I don't pay much attention to such transfers, although they could be annoying in some cases where a group changes hands, so to speak, every couple of years -- just because sceintists can't agree on its relationships with others, mostly due to new findings (or lack thereof :). Unfortunately, this often creates taxonomic confusion but the existing nomenclature doesn't provide means to avoid that.

(pillbugs, as far as i know, are crustaceans rather than insects -- but i'm quite clueless about common names, they mostly confuse me)

 
Clues
Well thank you V for the reply. I have already figured out that the
more I look at, the easier it is. I will wear out my literature before
long. Need to go have a drink before I tackle Arnett again. Tks
