Rhyncolus knowltoni (Thatcher, 1940)

Material examined.

Charlotte Co., St. Andrews , 45.0741°N, 67.0383°W, 22.VII.2012, R.P. Webster // Barrier beach (gravel), under large log (1, CMNC; 1, RWC) .

Distribution in Canada and Alaska.

AB, SK, MB, NB ( Bousquet et al. 2013). This is the first eastern record of this species. Previously, it was known from MB with additional records added from AB and SK by Douglas et al. (2013). Rhyncolus knowltoni (Thatcher) is associated with Populus tremuloides ( Douglas et al. (2013) and is undoubtedly more widespread than the records indicate.
