Gyrinus pleuralis Fall, 1922

Gyrinus pleuralis was reported from New Brunswick (as well as Ontario and Québec) by Roughley (1991). Oygur and Wolfe (1991), however, pointed out that this species is easily confused with G. affinis because the variations in body shape and colour overlap. Gyrinus pleuralis is a western species recorded in Canada from British Columbia to Saskatchewan ( Oygur and Wolfe 1991). Thus, previous reports of the species from New Brunswick would certainly have been in error and the species is removed from the faunal list of New Brunswick.
