Small Carabid - Scaritinae? - Semiardistomis viridis
4 miles West of Winnsboro, Wood County, Texas, USA
June 16, 2013
Size: ~ 6mm
Attached this thorax image trying to show the setigerous punctures that I can see from my scope. Not a lot of them but I think you can see the ones on the lower right portion of the thorax having the setigerous punctures. If S. viridis is suppose to have none, then this might be the S. puncticollis?? Help appreciated, and thank you both for the assistance so far....Gary

Both species of Semiardistomis viridis and S. puncticollis
show setae along borders of prontum but only S. puncticollis shows prominent setae also centrally and across entire pronotum. My previous use of pronotal "disk" refers to the dorsal central area. So you tell me, what do you see? I don't see obvious seta on the pronotal disk. The differences seen in specimens examined under scope are obvious. Origin of "puncticollis" is "punctured neck (= pronotum)".

Thank you so much...
for your time and expertise. I'm getting a much clearer idea of what I'm looking at now, and totally agree with you that it must be S.viridis. I'll move them over to that species, and again thanks for you help.

Gary
