Cryptophagus mainensis Casey, 1924 NEWFOUNDLAND: Steady Brook, July 10, 1949, E. Palmen (2, MZHF). NOVA SCOTIA: Cumberland Co.: Westchester-Londonderry, August 22, 1992, S. & J. Peck, forest road, car netting (1, JCC); Hants Co.: Panuke Lake, 16–29 July, 1997, D.J. Bishop, red spruce/eastern hemlock (old growth), FIT (1, NSMC); Panuke Lake, 29 July-13 Aug, 1997, D.J. Bishop, red spruce (45 years), FIT (1, NSMC); Panuke Lake, 29 July-13 Aug, 1997, D.J. Bishop, red spruce (45 years), FIT (1, NSMC). Cryptophagus mainensis is newly recorded in insular Newfoundland, Nova Scotia, and Canada as a whole (Fig. 3). This is a Nearctic species previously known only from Maine, New Hampshire, New York, and Ohio (Woodroffe and Coombs 1961; Chandler 2001). In Nova Scotia specimens were collected in red spruce (Picea rubens Sarg., Pinaceae) and mixed eastern hemlock (Tsuga canadensis (L.) Carr., Pinaceae) and red spruce forests varying in age from old growth (120+ years) to 45 years. This is the first habitat information about this species. It is a very distinctive species on account of its small size (1.5–1.7 mm.) and very large pronotal callosities which subtend 1/3 of the lateral margin of the pronotum.
