Small Brown Beetle - Ephistemus globulus

Small Brown Beetle - Ephistemus globulus
Cleveland, Cuyahoga County, Ohio, USA
July 1, 2011
Size: 1-2mm
Very small and tough for me to get a good photo of. I don't recognize the family but I'm assuming the very short bristly hairs (lateral photo shows them a little better) that cover the body give a clue.

followup: may or may not be a noteworthy record
as Dr Yves Bousquet told me last night, this sp. "is very likely introduced in North America and not a truly Holarctic species. (just what i thought. =v=) It is known in Canada from Ontario and British Columbia. Unfortunately I have no idea if it has been collected in the United States."
Anthony, could you pls describe the situation (habitat, technique) where this one had been collected?

This guy was collected at a garden within the urban core of Cleveland using a Combi-Trap about a meter off of the ground for aerial beetles (combination of a flight intercept trap and yellow pan trap see Duelli et al. 1999/Obrist and Duelli 2010). This particular garden has been an interesting and productive one, yielding three Blapstinus interruptus (in pitfalls/Det. C.A. Triplehorn) you will see if you scroll through my photos which is a rare/rarely collected species at least in Ohio among other things. There were plenty of Atomaria in this sample as well, maybe the result of an existing compost pile at the garden?

many thanks
sounds consistent with my idea of an environment where a rich adventive fauna (and flora!) would thrive; geographically, 'across the street' from the Ontario part of its NA range.
i know of no decent garden where Atomaria weren't aplenty --their ubiquity is notorious. lovely beasts, i wish they were as popular amongst collectors and enthusiasts as cicndelines or lucanids ))))))

V, regarding your previous comment, what is the best way to determine whether something has been collected in the States before?

the best -- and the only -- way i'm aware of... polling the specialists
--unless, that is, the species is covered in one of your handy general ref sources

followup: the status of our knowledge
nobody seems to know (incl. Colin Johnson and Rich Leschen), so i really have nobody else to run crying to...

Ephistemus sp., must be globulus
Moved from ID Request.

No wonder I didn't recognize it, so atypical of all of the other Cryptophagids I've come across...

to me it's just an Atomaria with a few pounds to lose...
