Gyrinus pugionis Fall

Note.

Eight specimens were collected from four different localities of Kings and Prince Counties (Table 2).

Habitat.

Robert (1955), Morrissette (1979) and Alarie (2009) reported Gyrinus pugionis from peaty or semi-peaty lakes; Robert (1955) mentioned that it invades narrow outflow streams from such lakes. Oygur and Wolfe (1991) reported it primarily (88%) from lentic habitats. In Prince Edward Island, most specimens were collected from lentic habitats (Tables 1-2).

Distribution in the Maritime Ecozone.

This species was reported from the Provinces of New Brunswick ( Roughley 1991a; Webster 2016) and Nova Scotia ( Roughley 1991a), and from the Magdalen Islands ( Alarie 2009).
