Moved tentatively; venustus looks identical from above...
...but 'anterior margin of prosternum of male with a stout spine, that of female with a V-shaped lobe' -- you may want to check that or add a closeup

Moved from The Casebearers.

 
prosternum shot added
I hope it's good enough to see the details you need.

 
thanks much -- the ID stays.

 
nice to see some details
what about C. bispinus. That one is also very similar from above. Do you know how that one could be distinguished from calidus as well.

 
no, sorry --
not offhand; the southern bispinus is not in the differential for New England fauna; White's key (available online; you probably have it anyway) couplets are evasive: overlapping size diff. in females & geography -- it boils down to aedeagi where the two coexist, which is GA-FL-OK
