NB (New Canadian record). This species was described from Cranberry Lake, NY (Notman, 1924: 270). No other localities or data were included at the time and the species has not been reported again until now.

Natural history.

In NB, this species was associated with various wetland habitats. Specimens were sifted from saturated moss in a mossy seepage near a creek in a hardwood forest, found in moss hummocks with grasses in an alder swamp, sifted from moist leaves on a vernal pond margin in an old red oak and red maple forest, sifted from grass litter on muddy soil along a stream, in moist leaf and grass litter near vernal pools in a wet alder swamp, and sifted from grass litter near a slow-flowing stream. One specimen was collected in a salt marsh by treading Spartina patens and other grasses near tidal pool. Adults were collected from April to July.
