ABSTRACT The distribution of the genus Paraleuctra (Hanson, 1941) in Canada, based on the examination of specimens in the Canadian National Collection of Insects, Arachnids and Nematodes, the University of Guelph Barcode of Life Data System website collection, and the Royal British Columbia Museum is presented. Most of the specimens in the Canadian National Collection of Insects, Arachnids and Nematodes (CNC; Ottawa, Ontario, Canada) were examined before the descriptions of R vershina and R alta. None of the specimens in the CNC, University of Guelph (UOG; Guelph, Ontario, Canada) Barcode of Life Data System (BOLD) collection, Royal British Columbia Museum collection (RBCM; Victoria, British Columbia, Canada), or the Illinois Natural History Survey (INHS; Champaign, Illinois, United States of America) were included in Stewart and Oswood (2006). Detailed collection data and photographs for specimens examined are also available at the following websites: the CNC online database (http://www.cnc-ottawa.ca/taxonomy/ SpecSearchD15.php) and the University of Guelph as part of the BOLD website (UOG) database, (http://v4.boldsystems.org/index.php/Public_BINSearch? searchtype=records; Ratnasingham and Hebert 2007).
