Only those species with at least five specimens collected are considered. Canadian provincial records summarized in Bousquet et al. [2]; other available distributional references are supplied below.
*distributional classes from Danks [7] A = Arctic, southern boundary north of the tree line; SA = southern Arctic, transcontinental north of the tree line; SAxB = southern Arctic excluding Beringia, transcontinental north of the tree line; WC = western and central, range from western North America east to Hudson Bay; S = southern, northern boundary at the tree line; SHA = southern high arctic, arctic species extending south of the tree line; SLA = southern low arctic, southern species extending north of the tree line.
** all Dytiscidae were collected in aquatic habitats.
