Parocyusa americana (Casey, 1906) View in CoL Figs 473-476

Parocyusa americana (For comparison with Parocyusa fuliginosa (Casey), see Brunke et al. 2012.)

Material examined.

New Brunswick, Carleton Co., Jackson Falls, 46.2257°N, 67.7437°W, 12.IX.2009, R.P. Webster, coll. // River margin near waterfall, splashing moss near splash zone of waterfall (1 ♀, RWC).

Natural history.

Brunke et al. (2012) reported specimens of this species from a hedgerow, from the bank of a sandy creek and from under a rock in a dry streambed. The specimen from NB was collected by splashing moss near the splash zone of a waterfall in September. Specimens from ON were collected during June, September, and October.

Distribution in Canada and Alaska.

ON, NB ( Bousquet et al. 2013). Brunke et al. (2012) reported Parocyusa americana for the first time for Canada based on specimens from ON and suggested that this species might be more widespread in northeastern North America in habitats near running water.

Comments.

Parocyusa americana may be distinguished from Parocyusa fuliginosa by antennal articles VI-X elongate (subquadrate to transverse in Parocyusa fuliginosa ), by elongate pronotum equal in length to elytra (pronotum shorter than elytra in Parocyusa fuliginosa ), and by the shape of spermatheca. The male of Parocyusa americana is unknown.
