found in the province (Paquin and Duperre 2006). Paquin et al. (2008a) also documented 

 the occurrence of three species that maintain viable populations in an artificial ecosystem of 

 Montreal, but are not yet established on the territory. 



In this paper, we propose a second update of the faunistic knowledge for Quebec 

 spiders - following Paquin and Duperre (2006) - with eight new species records for the 

 province. We provide accurate illustrations with angles and style comparable to Paquin and 

 Duperre (2003) to ease comparison and species level identification. Up-to-date faunistic 

 knowledge facilitates the detection of introductions, the recognition of invasive species, 

 or potential changes in species distribution. Shifts in ranges may be induced by climatic 

 changes (Dukes and Mooney 1 999; Parmesan and Yohe 2003) that push further north species 

 that were earlier restricted to regions south of the province. 



Materials and Methods 



Specimen Collection 



The records reported here were gathered from three bio-inventories/ecological 

 projects carried out in different regions of Quebec: the spiders of the Pare National de la 

 Yamaska (Paquin et al. 2008b); the arboreal spider fauna of sugar maple forests in southern 

 Quebec: Oka and Mont-Saint-Bruno National Parks, and the Mont Saint-Hilaire world 

 biosphere reserve (M. Larrivee); and the spider bio-inventory of the Reserve Nationale de 

 faune du cap Tourmente (C. Simard). 



Specimen Examination 



Specimens were examined in 70% ethanol under an SMZ-U Nikon dissection 

 microscope. A Nikon Coolpix 950 digital camera attached to the microscope was used to 

 photograph all the structures to illustrate. The digital photos were used to trace proportions 

 and the illustrations were detailed and shaded by referring back to the structure under 

 the microscope. Female genitalia were excised using a sharp entomological needle and 

 transferred to lactic acid to clear non-chitinous tissues. A temporary lactic acid mount 

 was used to examine the genitalia under the compound microscope. After each record, 

 an acronym indicates where the specimens are deposited: CPAD: Collection of Paquin- 

 Duperre (Shefford, Quebec, Canada); CNC: Canadian National Collection of Insects and 

 Arachnids (Ottawa, Ontario, Canada). 



The general terminology follows Ubick et al. (2005), but Dondale et al. (2003), 

 Levi (1953, 1957), Millidge (1981) and Piel (1992) were also consulted. Latitude and 

 longitude data are given in decimals and should be considered an approximation. Other 

 acronyms used are MCZ (Museum of Comparative Zoology at Harvard, Cambridge, 

 Massachusetts, U.S.A.), and AMNH (American Museum of Natural History, New York, 

 New York, U.S.A.). Abbreviations used: A atrium, C conductor, CD copulatory ducts, CO 

 copulatory openings, E embolus, M suprategular apophysis, membranous part, MA median 

 apophysis, PTA palpal tibia apophysis, R radix, S spermathecae, SD sperm duct, SubTA 

 subterminal apophysis, TA terminal apophysis, TP tailpiece.
