Chlaenius nemoralis - male

Chlaenius nemoralis - Male
Hancock County, Indiana, USA
July 3, 2011
Size: 13 mm
Fairly sure this is Chlaenius nemoralis, but trying to judge the appearance of the pronotum (more opaque vs more shiny in C. tricolor) can be tricky.

C. tricolor ?
Antennomeres 4-11 being darker suggests C. tricolor

 
nemoralis vs tricolor
This Chlaenius clearly has the non-shiny pronotum due to granular microsculpture, which indicates C. nemoralis. I have seen that Ciegler (1) mentions antennal color (pale throughout for C. nemoralis and 4-11 darkened for C. tricolor) as a separator for the two species, but I don't know if that is a reliable characteristic.
