Bembidion 01 - Bembidion texanum

Bembidion 01 - Bembidion texanum
Martel Forest, Tippecanoe County, Indiana, USA
April 6, 2008
Size: ~ 5.8 mm
Any suggestions for this one?

Collected in dry sandy streambed. Dorsum dark with apex of elytra becoming brownish.

Bembidion texanum
Moved from Bembidion. David Maddison says this "is either Bembidion texanum or the related B. lacunarium. Easiest way to tell the difference is to see if there is microsculpture in main part of the elytra. If there is - B. lacunarium. If not, B. texanum."

It lacks the microsculpture (examined under high power), thus B. texanum.

Also have a B. lacunarium from this same site.
