Coleoptera Beetles - Macropogon testaceipennis

Coleoptera Beetles - Macropogon testaceipennis
Angelo Coast Range Reserve, Mendocino County, California, USA
July 2, 2004
Size: about 7.6 mm
This beetle was captured in a sweep net at a large grassy meadow in the Angelo Reserve located near the Bay Area. I’m looking to identify this beetle as close as the Genus name but if anyone can help narrow it down that would be wonderful. The markings on the bottom are subdivisions of inches. This is for an undergraduate project that I undertook a few weeks ago. If you would like to know more about it please email me. Thank you!

More info from Blake (parts of 2 messages):
[Sophia] is an undergraduate here at Berkeley who saw a presentation I gave a little over a year ago and expressed interest in the invertebrates I had collected. As Sofia pondered potential projects for summer research, I gave her a disk of photographs I had taken of several of the invertebrates collected in sweeps and pitfall traps in a grassy meadow at the Angelo Coast Range Reserve, elevation approximately 1200' (Mendocino County, California 39 43' 45" N, 123 38' 40" W). All scale bars in the photographs are in millimeters. Invertebrates have been collected on May 31st, July 2, and August 1st for the past six years.

I collected that [species of] Artematopodid on July 2 2003, July 2, 2004 and May 31, 2006. Three of four individuals were collected in plots that had been subjected to experimentally extended rainfall -- 14 to 16 mm added from Raincurtain sprinklers every 3 days for 87 days from April through June.

Vegetation is a well-mixed assemblage of forbs and grasses of native and exotic origin. Exotic annual grasses from the Mediterranean represent the greatest portion of biomass, with the perennial forbs Eschscholzia californica (California poppy), Sanicula bipinnatifida (Shoe Buttons), and Rumex acetosella (Sheep sorrel) and the annual forbs Trichostemma lanceolatum (Vinegar weed) and Eremocarpus setigerus (Turkey mullein) also common.

date
Blake emailed me the date of this photo, so I added it. He says the scale bars in the photograph are in millimeters, which means the length is between 7 & 8 mm.
Sofia used photos Blake gave her for a potential project for summer research. I know Blake because Berkeley is a small place and everyone knows everyone ... (ok, not really, but apparently it's small enough)

New family for bugguide!
We didn't notice this when Don Chandler gave it a name but let us offer a belated congratulations on filling one more empty beetle family slot on bugguide.

We'd like to know:
Did you mean the Angelo Coast Range Reserve in Mendocino County? (We assumed you did.)
Are the "subdivisions of inches" 1/16 or 1/32 of an inch? (We assumed the former.)
What date (or around what date) was this collected?

 
some info...
These photos were actually taken by Blake Suttle. Yes, they were taken at the Angelo Coast Range Reserve in Mendocino County. I've emailed him to see if he can provide the other info.

 
I'm so confused.
Is Sofia Peeva Blake Suttle's Web handle or are they two people? And how do *you* know, Joyce?? Not that it matters. I hope we get some more specimen info/verification.

Artematopodidae: Macropogon testaceipennis?
Fits the description well for Macropogon testaceipennis in Hatch (Beetles of the Pacific Northwest). This is the only light colored member of this family in North America I believe - the rest are dark brown/black.

Coleoptera: Artematopodidae, genus?
I was hoping some Californian may have jumped on this one, as it has been a long time since this displaced Californian has seen one of these. It looks like one of the genera of the Artematopodidae, Macropogon or Eurypogon (or some other genus, there aren't that many). This group of genera used to be placed in the Dascillidae, but not for some time now.
