Darkling Beetle - Coelocnemis

Darkling Beetle - Coelocnemis
Junction Hwy's 36 and A21 in Westwood by outdoor light; elevation 5100ft, Lassen County, California, USA
July 23, 2010
Size: body length 26mm
Found at night walking about on the pavement under a bright outdoor light. I often find these beetles under old tree wood in the springtime.

Images of this individual: tag all
Darkling Beetle - Coelocnemis Darkling Beetle - Coelocnemis

Moved back to genus for now...
Moved from Coelocnemis magna.

Moved tentatively
Moved from Coelocnemis.

Moved from Darkling Beetles.

I also think Coelocnemis
Habitat is correct. Too bad the tibial setae are not visible.

I do not think this is magna
The shape and texture are wrong. The geographic range of magna and californica overlap, but this individual is most consistent with californica. I think I can rule out rugulosa also. A view of the underside would clinch the ID.

... for the update. I may still have this specimen; if I do I will add a ventral image.

only 2 sp it can be
only 2 sp it can be
- Hypomeron smooth; punctures obsolete or very fine, sparse, separated by two or three times diameter; subocular rugosity not extending to midventral line of head ---> C. magna LeConte

- Hypomeron distinctly punctate or punctato-rugose, punctures separated by one to two times diameter; subocular rugosity extending as continuous band across postoral region ---> C. californica Mannerheim

check out(1) -- something for you to gloat about and feel vindicated :))

Ah! to be human; or as my wife tells me from time to time, "to error is human" :))


we can't afford guess-based guide placement
Moved from Eleodes.

how was the ID obtained? doesn't look like Eleodes to me
in fact, the beast likely belongs in a diff. subfamily (i'd say, Stenochiinae: Cnodalonini) -- but i'm no teneb expert, and those may look notoriously deceptive

Just a bad Guess!
Thanks for the correction!

I was leaning towards Coelocnemis, too.
