Chlaenius impunctifrons - female

Chlaenius impunctifrons - Female
Wisconsin River at HWY 130 - found under shoreline debris, Sauk County, Wisconsin, USA
August 15, 2013
Size: about 15mm
I believe this specimen to be Chlaenius impunctifrons.

I keyed it out using the Bell monograph, and double checked it using Bousquet 2010.

Key traits include 3rd antennal segment not elongate, tip of prosternum lacking a margin, pronotum not sinuate basally, legs reddish, head lacking dorsal setae, pronotum flattened laterally.

I noticed no examples from Wisconsin were yet on the guide so I thought I would add it.

looks good -- thanks for sharing
