August 8, 2011
Size: 2.2mm
Attracted to lights.

Moved from Trechinae.

Paratachys oblitus (Casey)
based on my microscopic examination of this specimen which is now a photo-voucher in the P.W.Messer collection. New to BugGuide. Thanks Tom.

Range: primarily northeast.
Distinguished from similar spp. by uniformly dark dorsum (no elytral cloud); poorly defined elytral striae lateral to the first; pronotum with relatively straight sides (barely sinuate) and hind angles rounder.

syn. Tachys obliquus (Casey) used in Lindroth (1966).

New species record for MA
which I conveyed to Yves Bousquet for his catalogue revision.

Moved from Ground Beetles.
I think this is the first I've seen at my lights. It must have come up from the wetland out back.

very Trechus-y
don't remember ever seeing them @ my lights
