Darkling beetle  Eleodes - Eleodes longicollis

Darkling beetle Eleodes - Eleodes longicollis
rural, Elbert County, Colorado, USA
September 30, 2008
Size: 1"
This looks like a Darkling beetle, but I didn't find any with a smooth back in the guide. It was black in color, but if the light was just right, it showed some red.

Late to the party
looks like I'm late to the party, but this is a Eleodes longicollis see

 
Yup.
E. longicollis - this form with the red stripe was described as E. haydenii, but just seems to be populational variation.

Moved
Moved from Opatrinae.

Eleodes
they come in all shapes, textures, and finish options; plenty of smooth ones

 
Thanks
Thanks for the ID.

 
Teneral?
In my experience, I find many teneral (newly-emerged) beetles to be this color of red or reddish brown, and soft, until the cuticle hardens and the normal pigments set in. This can take several days.

 
not necessarily
as i've learned the other day, some Eleodes spp. keep such reddish axial tint on elytra for life
