Heterosternuta wickhami (Zaitzev)

Notes.

This species is reported from nine specimens collected in Victoria County and Inverness County (samples I78, I79, V85).

Habitat.

Like the previous species all specimens were collected in gravel along the margins of streams. Matta and Wolfe (1981) state this species is most common at the margin of medium to small streams.

Distribution in the Maritime Ecozone.

This is the first record of H. wickhami in the Maritimes. Prior to this study it had only been reported from Ontario and Québec. Its presence on Cape Breton Island represents a significant extension of this species to eastern Canada ( Bousquet et al. 2013).
