Bembidion (Pseudoperyphus) rufotinctum Chaudoir, 1868** Map 3

Material examined.

New Brunswick, Carleton Co., Jackson Falls, 46.2257°N, 67.7437°W, 12.IX.2009, 22.V.2010, R. P. Webster, river margin above waterfall, on exposed bedrock (23, CNC, NBM, RWC).

Collection and habitat data.

Bembidion rufotinctum lives in cracks of emergent bedrock in river channels ( Cooper 1976; Davidson 1981). A typical habitat for this species is illustrated by Maddison (2008; Fig. 1 D, p. 148). In New Brunswick, adults were collected during May and September by splashing exposed bed rock adjacent to fast-flowing water above a waterfall. It took 5-10 min. before the adults appeared on the exposed rock surfaces. The exposed bedrock at this site was similar to that illustrated by Maddison (2008), although less extensive.

Distribution in Canada and Alaska.

QC, NB ( Bousquet 1991; Maddison 2008). The closest localities of Bembidion rufotinctum to New Brunswick are in Quebec, Ste.- Raphaël, Bellechasse Co., on exposed bedrock near waterfalls along the Rivière du Sud (Webster, unpublished), and in New Hampshire ( Maddison 2008). Bembidion rufotinctum has not yet been reported from Maine ( Majka et al. 2011) but will undoubtedly be found in the state once appropriate habitats are sampled.
