New Brunswick, Restigouche Co., Pollard Brook at Pollard Rd., 47.9861°N, 67.6945°W, 31.VII.2012, R.P. Webster // Clear rocky stream, splashing gravel margin (1 ♂, RWC).

Natural history.

The only specimen of Parocyusa fuliginosa from NB was collected by splashing the gravel margin of a clear rocky stream in late July. In LB, adults were collected from rocks and gravel along a stream margin in early August.

Distribution in Canada and Alaska.

ON, NB, LB (Bousquet et al. 2013). Klimaszewski et al. (2011) reported this species for the first time for Canada from LB. Later, Brunke et al. (2012) reported an additional specimen from ON and suggested that this species might be more widespread in northeastern North America in habitats near running water.
