, pitfall, 1ɗ 1Ψ, M. Larrivée (

Diagnosis.—
Males are characterised by the large tegular apophysis (TA) arising basally (
Fig. 43
) and the shape of the retrolateral apophysis (RTA) (
Fig. 44
). Females are characterised by the chevron pattern on the abdomen (
Fig. 42
), the presence of a median hoodlike pocket (arrow,
Fig. 45
) and the elongated, parallel spermathecae (S) (
Figs 45– 46
).
Distribution.—
From Québec (present records) to Alberta, with a record from Colorado. The few known specimens suggest that the species is boreal with a southern extension in the Rockies.
Remark.—
The Jamésie record given here comes from a naturally burned Black Spruce forest. The species was never collected again in any other habitat despite an intense sampling effort in that region.
Larrivée
et al
. (2005)
report the occurrence of the species in the province without details.

On Jerzy Proszynski’s web site (
Proszynski 2003
),
P. montanus
is listed as a junior synonym of the Palearctic species
P. lapponicus
(Sundevall 1833)
, but that synonymy has never been officially published. Illustrations provided on this web site show small differences in the spermathecae between Palearctic and Nearctic specimens. We prefer to use
P. montanus
for specimens collected in North
America
until that question is formally addressed.
