Click beetle at the lights - Diplostethus opacicollis

Click beetle at the lights - Diplostethus opacicollis
Santa Rita Experimental Range Station, Florida Canyon, Pima County, Arizona, USA
July 25, 2013
I think I measured this at 24mm but I could have it confused with another click beetle. It was crazy at the lights! gathering_2013

Moved Tentatively
Your sampling from this locality contained both D. peninsularis and D. opacicollis. The morphologic features separating them are visible ventro-laterally (primarily the prosternal process and mesosternal fossa).
When series of the two species are displayed side-by-side, opacicollis tends to be darker/black while peninsularis tends to be a lighter brownish. As such I am going to make the risky assumption this is one of the peninsularis you collected :)

Moved from Diplostethus.

Moved
Three species possible in southern AZ; I will look at the vouchers you sent to see if there was only one species in the sampling. If so, this would most-likely be that species.
I have the specimens mounted but not ID'd yet :).

Moved from Beetles.

 
by the way
This one is probably ~15.0 mm

Diplostethus?
