Negastriinae

Negastrius exiguus (Randall, 1838)

NEW BRUNSWICK: Restigouche Co.: Restigouche River and Stillwater Brook, 26.vi.2000, R.P. Webster, gravel on river margin, RWC.

Newly recorded from New Brunswick and the Maritime Provinces as a whole. Collected from a farm creek, drift from a lake, and on a fern (Stibick 1990). Common on sandy shores of streams ( Downie & Arnett 1996). Negastrius (sensu lato) species have been reported only in association with riparian habitats ( Wells 1996).

Paradonus olivereae Stibick, 1991

NEW BRUNSWICK: Restigouche Co.: Restigouche River and Stillwater Brook, 26.vi.2000, R.P. Webster, gravel on river margin, (2), RWC. NOVA SCOTIA: Colchester Co.: Portapique, 28.vii.1927, C.A. Frost, CNC; Guysborough Co.: Trafalgar, 19.vii.1992, S. and J. Peck, car net, JCC.

Newly recorded from New Brunswick. Several localities along a creek, a lake, and falls suggest waterside habitats ( Stibick 1991). Larvae of closely related species are found in sandy soils along waterways where they are predators on small invertebrates (unpublished data). Prior to Stibick's description of P. olivereae, Bousquet (1991) reported Paradonus obliquatulus (Melsheimer) from Nova Scotia based on the above specimen from Portapique. Consequently P. obliquatulus is removed from the faunal list for Nova Scotia.
