unknown beetle - Eulimnichus

unknown beetle - Eulimnichus
Medford, (~15 miles east of Philadelphia, PA) Burlington County, New Jersey, USA
July 26, 2006
Size: ~1.9mm
tiny convex beetle with lots of hair (not the moth scales), sometimes appears to have silver "spots" down lateral and apical elytra (but might just be my imagination)

any suggestions?

Thank you all
Thank you all for your assistance. Assuming this one stays as Limnichidae, there are lots of good images on-line from LeConte's collection at the MCZ site, including Limnichites punctatus LeConte 1854 (Limnichus) shown here , which might be a good possibility and is the only Limnichidae listed on the UNH site. Downie and Arnett list 5 others.
(These MCZ photos show me just how far my own microscope shots have yet to go :( But you can definitely see the silver "swirls" on a few of these (L. nebulosus).

Thanks again!
Tim

 
Eulimnichus cf. nitidulus LeConte, 1854
perhaps what is listed in D&A as sculpticeps (Casey)

 
sculpticeps Casey is synonym of E. ater (LeConte)
per Wooldridge 1978

 
Limnichidae
I offhand can't think of the definitive character as to why it is not a byrrhid, but byrrhids have the dorsal setae denser or thicker, or different in some way, while this is very typical density and length for limnichids.

Limnichidae
- my guess. Silvery spots may be due to reflective pubescence in swirled arrangement.

 
Limnichidae
I agree with Boris. Definitely a limnichid.

 
Why?:-)
Why is it 'not' a byrrhid? That was my first thought, also.

 
I can see the same swirled arrangement
on the sole representative of this family already posted on bugguide. Good work, Tim!

 
Limnichidae
Here in Iquitos I have thousands of Limnichidae at lights and this is definitively one. The antenna and general bodyshape are different. I never see any Byrrhids at lights, but I´m not sure if that´s much of an argument.

Just a guess: Byrrhidae... I'
Just a guess: Byrrhidae... I'll be interested to see what are beetle-ologists say on this one.
