Heterosternuta allegheniana (Matta & Wolfe)

Notes.

This species is reported from 39 specimens collected in Richmond County and Inverness County (samples R31, R32, R64, I72).

Habitat.

All specimens were collected on pebble substrate or in leaf litter along the margin of cold creek and streams in accordance with Matta and Wolfe (1981).

Distribution in the Maritime Ecozone.

Prior to this study, Heterosternuta allegheniana had only been reported from New Brunswick and southern Québec ( Bousquet et al. 2013). Its presence in Nova Scotia therefore represents its easternmost distribution in Canada.
