Elaphropus sp.? - Elaphropus anceps

Elaphropus sp.? - Elaphropus anceps
Swanton, Franklin County, Vermont, USA
November 14, 2007
Size: about 2-3mm
Found under a rock.

Moved
Moved from Elaphropus.

size was a guess
It was more likely a little over 2mm. I've adjusted the approximation.

size confirmation please
Tom, are you sure of size "1.5mm" as only Polyderis laevis gets that small? I believe the convex body shape and pronotum outline shown better fits Elaphropus but almost all those species are in the 2 - 3 mm range. See past BG images of Polyderis vs Elaphropus. At any rate, there are about 10 species of Elaphropus known in Vermont but they have subtle differences difficult to photograph. The uniform red-brown color (assuming not from teneral state) would likely limit the choices to a few species as most species are dark. I'm not sure if life cycle events of Elaphropus would preclude tenerals in November.

 
I now favor Elaphropus anceps
based on dorsum with rather uniform brownish color and hint of pronotal sinuation.
