Material examined.— Canada: Québec: Pontiac: Les Collinesdel’Outaouais, 2 km North of Eardley [45°34’N, 76°05’W] 20.viii.2004, sifting litter in maple forest, 4ɗ 4Ψ, P. Paquin & N. Dupérré ( CPAD); Pontiac: Les Collinesdel’Outaouais, 2 km North of Eardley [45°34’N, 76°05’W] 20.viii.2004, sifting moss on rocks in maple forest, 1Ψ, P. Paquin & N. Dupérré ( CPAD); Pontiac: Les Collinesdel’Outaouais, 2 km North of Eardley [45°34’N, 76°05’W] 20.viii.2004, sifting litter in oakmaple forest, 1Ψ, P. Paquin & N. Dupérré ( CPAD); Kazabazua, La ValléedelaGatineau, Lac Danford [45°57’N, 76°08’W] 16.vi.2001, sifting litter (poplar/ Alnus ), 1ɗ, P. Paquin & N. Dupérré ( CPAD).
Diagnosis.— The male of the species is recognised by an abdominal scutum covering whole dorsum, a palp with long thin embolus (E) ( Fig. 71 View FIGURES 64 – 73. 64 – 68 ), and a curved conductor (C) ( Fig. 71 View FIGURES 64 – 73. 64 – 68 ). Females are characterised by a pale abdomen lacking a dorsal scutum, an epigynum with a wellsclerotized posterior epigynal margin (PEM) ( Fig. 72 View FIGURES 64 – 73. 64 – 68 ), complex copulatory ducts (CD), and oval spermathecae (S) ( Fig. 73 View FIGURES 64 – 73. 64 – 68 ).
Distribution.— Known from Québec (present records) and Wisconsin south to Florida and Mississippi (see Levi 1957b).
Remark.— Kaston (1948) reported that P. hirsutum is associated with forest litter, which is supported by our collection data. The distribution of the species and the records from deciduous litter suggest that the species may reach its northern limit below the conifer and boreal forests of North America. This species is likely to be confused with a small Erigoninae (Linyphiidae) .
