Amerinus linearis
This rare species is at the top of my personal "want" list for North American Carabidae with respect to learning new range extensions, recent evidence that it is not extirpated from its historical range, and acquiring at least one specimen (donated or otherwise) for my synoptic-study collection of North American Carabidae. The historical range according to the catalogue by Bousquet & Larochelle (1993) is AR, DC, IL, IN, LA, MA, MO, MS, NC, NJ, NY, ON, PA, VA, WI. Everyone please check private and local institutional collections for collection records obtained within the last few years. Published body length range is 4.2 - 4.8 mm, therefore small and could easily be overlooked. This harpaline has an unusually narrow and prolonged pronotum. Habitat is in the vicinity of swampy places or recently flooded areas (under cover daytime in sandy wet soil, not subterranean). Thanks Kyle for sparking our interest.

 
I would also
I would also like to catch one of these; rarity is usually a bigger draw for me than size or shine. Although, big shiny rare things are pretty nice. This is our only specimen and I've collected my county fairly well without success. Hopefully by showing an example it may be recognized by someone in the wild. I know I usually ignore all the Steno. and Brady. that come to my lights.

 
NJ backyard
habitat describes my NJ backyard (at least after a good rain). I'll keep an eye out for them. Do you know if they come to lights (other collection techniques, pit-fall?)?

 
Yes,
they are known to fly to lights; also reported under leaf litter during the day, therefore to be had in pitfall traps. I proclaim that the race to find and capture one live Amerinus linearis in North America is on!

 
Got one
Hi Peter,

Not sure if this is still a topic of interest for you, but I just identified a specimen of this species for an Ontario survey project I am involved in. The Blatchley specimen helped me confirm my ID.
Have you had any luck finding this species elsewhere in the northeast??

Cheers,
Adam

 
Wonderful to have
another collection record. Adam, hopefully yours was captured relatively recently. Can you give us the details? Amerinus linearis is still a species void in my reference collection, so a donated specimen or possible trade for it would be much appreciated.

 
Unfortunately, the specimen i
Unfortunately, the specimen is not in my personal collection (it's at Guelph University) otherwise I'd have been happy to donate it.
However, I can certainly provide the data:

CANADA: ON: Hald.-Norfolk Co., Cronmiller Prop., 42.67 -80.49, forest nr. vernal pools, malaise pans, 17 to 30-V-2011, Brunke and Paiero, 1.

The specimen was collected in between two large vernal pools within a very large complex of slough forest. The particular property is immediately adjacent to an old growth slough forest and the general area is known for its sandy soils, and alternating ridges and flooded low areas. So basically, it fits perfectly with what was previously known.

Hope this is useful, glad to be able to contribute!
Adam
