The semi-aquatic spider genus Dolomedes (Araneae Pisauridae) in the Canadian Maritime Provinces

The fishing (dock or wharf) spiders (Dolomedes spp. Latreille, 1804) of the Maritime Provinces of Canada were surveyed through a combination of new collecting and examination of specimens from the Nova Scotia Museum and the New Brunswick Museum. Four species (Dolomedes tenebrosus Hentz, 1844, Dolomedes triton (Walckenaer, 1837), Dolomedes scriptus Hentz, 1845, and Dolomedes striatus Giebel, 1869) were represented in collections made between 1961 and 2011 from New Brunswick and Nova Scotia, and Dolomedes triton was collected on Prince Edward Island in 2010 and 2011. Dolomedes is recorded for the first time in Prince Edward Island, and Dolomedes triton is recorded for the first time in the Maritime Provinces, extending its reported known eastern range from Maine and southern Québec.
