Material examined.— Canada: Québec: Kazabazua, La ValléedelaGatineau, Lac Danford [ 45°57’N, 76°08’W] 22.ix.2004, beating vegetation along a trail to a fen, 2ɗ 5Ψ, P. Paquin & N. Dupérré ( CPAD).
Diagnosis.—This species is very similar to C. nigriceps(see Paquin & Dupérré 2003, figs 879–882) but males differ from the latter by the longer embolus (E) ( Fig. 21) and the shape of the palpal tibia ( Fig. 23). Females differ by the median region of the epigynal plate shaped like an invertedT (arrow) and by the oval spermathecae (S) oriented obliquely ( Fig. 24).
Distribution.—Widespread on the eastern side of the continent, north from New Brunswick, Nova Scotiaand Minnesota, south to Louisiana and Georgia.
Remark.— Kaston (1948)and Hutchinson & Bélanger (1994)report that C. nigripalpishas been collected mainly from vegetation, which is supported by our collections. This is unusual for an erigonine Linyphiidaeas most species are ground dwellers.
