Enaphalodes cortiphagus - female
Copyright © 2011 Frank Guarnieri

Enaphalodes cortiphagus - Female
7 Km East of Paw Paw, Morgan County, West Virginia, USA
July 25, 1999
Size: 25 mm
Collected at Ultra-Violet light. 39.5224, -78.3641

Steven Lingafelter at the Smithsonian made the ID based on microscopic inspection of the humeral punctation. Also note the more evenly distributed whitish pubescence (typically more patchy and yellow in E. atomarius). I only have three specimens of E. cortiphagus so I don't know if this would hold true for a larger series, but the background integument color seems to be intermediate between E. atomarius (dark chestnut brown) and E. rufulus (light reddish brown).

awesome...
thank you so much again for posting your wonderful images of those tough-to-tell-apart beetles.
Frank, would you consider rotating the beetles head up, the way they are traditionally shown both in ref. publications and web sites?
they are much easier to compare when put side-by-side...

Vassili,oops so
Vassili,
oops sorry about that. I remember you asked earlier and then forgot. Just because my small computer screen can usually fit more of the beetle that way. I'm using ancient mac and even older imaging softwear and then pixels get screwed up if I rotate 90 degrees. But from now on promise to shoot the images with correct orientation!
