Gyrinus aquiris LeConte

Note.

Gyrinus aquiris was the most abundant (45.4%) and one of the most frequently collected gyrinid (6%) in this survey. The species was collected in every county of Prince Edward Island (Table 2).

Habitat.

In Prince Edward Island, Gyrinus aquiris was collected both from lotic (50%) and lentic (50%) environments (Tables 1-2), which is similar to the observations made by Alarie (2009) in the Magdalen Islands. Oygur and Wolfe (1991), however, reported 80% of specimens from lentic habitats whereas Morrissette (1979) reported the species from ponds and lakes invaded by aquatic plants.

Distribution in the Maritime Ecozone.

Gyrinus aquiris was reported from the Magdalen Islands ( Alarie 2009), and the Maritime Provinces of New Brunswick ( Oygur and Wolfe 1991; Roughley 1991a; Webster 2016) and Nova Scotia ( Campbell et al. 1987). Although Roughley (1991a) reported it from Prince Edward Island, Majka (2008) removed it from the province’s faunal list since there were no voucher specimens or published records.
