Carabid - Selenophorus gagatinus - Male
Groton, Middlesex County, Massachusetts, USA
April 16, 2012
Size: 7mm

good lesson guys
Moved from Harpalus fulgens.

Selenophorus gagatinus
based on my microscopic examination of this male specimen which is now a photo-voucher in the P.W.Messer collection. Thanks Tom.

While superficially like northeastern Discoderus parallelus with its elytral striae 2,5,7 punctate and its wide pronotum strongly convex, cannot be D. parallelus because dorsum is very shiny (obsolete microsculpture) and the male protarsi are distinctly dilated.

Moved from Ground Beetles.
When Peter gets the specimen we'll know for sure.

habitus consistent w/Harpalus fulgens, to my eye
by no means an ID!

thats what I thought too
