Abstract


Ad hoc collections of spiders were made in August and early September 2003 and pitfall trap collections were conducted from June to October in 2004 and 2005 in southern Labrador. These collections represent the first systematic spider sampling for the most easterly area of mainland Canada. In total, 161 species in 15 families were identified to genus and species and 16 were indeterminate. Of the identified species, 89 were new records for Labrador and, of those, 16 species were new records for the province. In total, 94 species (58.4%) have Nearctic distributions and 67 species (41.6%) are Holarctic. No Palearctic species were found. Our study brings the number of spider species recorded in the province of Newfoundland and Labrador to 377 (213 in Labrador).
