This species is reported from several specimens collected in Prince and Kings Counties (Table 2). Habitat. In Newfoundland, this species has been collected from flooded grasses and emergent Carex along the margins of beaver ponds and roadside ponds. Specimens, which occurred on peaty substrates near boggy areas, were collected from areas exposed to the sun as well as from shorelines shaded by overhanging alder. In Prince Edward Island, Hydroporus goosei was collected in similar habitats, in addition to Sphagnum bogs and eutrophic creeks (Table 1). Distribution in the Maritime Ecozone. This large, distinctive Hydroporus Clairville species has generally been confused with Hydroporus rectus Fall. In the Maritime ecozone, Hydroporus gossei is also reported from the neighboring Province of New Brunswick ( Larson et al. 2000 ).
