Fabogethes nigrescens --det. A.R. Cline
Moved from Brassicogethes.

do you still have it? mind reshooting?

 
look around
should have it - I'll look around. This was imaged when I was still pointing a camera through the eyepieces of my steroscope (yuck!). I should be able to be considerably better these days.

And I think I get these fairly regularly on flowers incl. wild mustard, so should be easy to find some more come early spring.

 
great
by far the most important feature is the outer armature/denticulation and overall shape of the foretibiae; the texture of the dorsum, pronotal side margins & the general body outline also help a lot

Moved from Acrotrichis.

 
Definitely not Ptiliidae.
Definitely not Ptiliidae.

Sorry, that´s wrong!
I´d say, it is Meligethes sp. in Nitidulidae.

Ptilliids never have enlarged tibiae and antennae with a round club.

Ptiliidae: Acrotrichis sp.
Our largest ptiliids.

 
Thanks Don,
If this is the biggest, I don't know what I'd do with the "merely average" or smaller ones. What type of equipment and magnification do you use if you want to key these size beetles? I've got a stereo macroscope with 10x/20x which I'm pleased with for larger subjects, and some 20x eyepieces which get me to 40x, but not at the sharpness I'd desire (though perhaps a good cleaning would help too)
