Ceratinopsis nigripalpis Emerton 1882  

( Figs 21–24 View FIGURES 14 – 24. 14 – 16 )

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, 2 ɗ 5 Ψ, 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 View FIGURES 14 – 24. 14 – 16 ) and the shape of the palpal tibia ( Fig. 23 View FIGURES 14 – 24. 14 – 16 ). 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 View FIGURES 14 – 24. 14 – 16 ).

Distribution.— Widespread on the eastern side of the continent, north from New Brunswick, Nova Scotia and Minnesota, south to Louisiana and Georgia.

Remark.— Kaston (1948) and Hutchinson & Bélanger (1994) report that C. nigripalpis   has been collected mainly from vegetation, which is supported by our collections. This is unusual for an erigonine Linyphiidae   as most species are ground dwellers.
