Identification
Don Buckle told me that, "The teeth bordering the carapace are one of the distinctive characters for the genus." … John Sloan, 17 February, 2012 - 2:00pm


Palp with tibia for comparison:(E. aletris, E. atra, E. autumnalis, E. blaesa, E. dentigera, E. dentosa)
Range
Common and widespread
Remarks
Of western Washington: "E. dentosa is not as common in western WA as E. aletris, but occurs in "pioneer species" habitats like agricultural fields, mud flats, and recently cleared ground." - pers. comm. Rod Crawford (here)

"Erigone dentosa outnumbers all other Erigoninae species combined throughout much of the Pacific coast states." - 2008 pers. comm. Devin Carroll
