Holotype.
Male (Figs 86, 87) in UBC-SEM, with data: Canada: British Columbia: Mt. Baldy.

, 1180 m elev. 17 May 2013 W.Maddison & H. Proctor WPM#13-014.
Paratypes
(3♂♂ 2♀♀). Same data as holotype (1♂ specimen NA13-6071 and 1♀ specimen NA13-6083 in UBC-SEM). Canada: British Columbia: W of Midway, along HWY 3, 3.0 km E of crossing of Kettle River with HWY 3, ca.
49.0°N
118.83°W
, 2 May 1982, W. & D. Maddison, WPM#82-019 (1♂1♀ in CNC, 1♂ in AMNH).
Etymology.
Named for the country of the type locality, in honour of the 150th anniversary of
Canada's
confederation.
Diagnosis.
A typical member of
Pellenattus
with striped markings, more contrasting in males than females.
Pellenes canadensis
can be distinguished by the TmA being only slightly smaller than the embolus, diverging from the embolus initially, then curving distally to touch the tip of the embolus.
Pellenes levii
has a similar palp, but its TmA is shorter and considerably narrower, only 1/4 to 1/3 the width of the embolus, and also is pressed against the embolus its entire length (
Lowrie and Gertsch 1955
, figure 17; holotype in AMNH examined).
Description.
Male (focal specimen: holotype). Carapace length 2.0; abdomen length 2.1. Structure of body typical for
Pellenattus
. Embolus a short pointed blade, accompanied by a TmA of almost the same size, which opposes the embolus like a thumb against a forefinger (Fig. 86). The RTA is broad but pointed (Fig. 87). The cymbial lobe is small but distinct, projecting toward the retrolateral (e.g., visible behind the RTA in Fig. 86). Colour: Black except for paler femur, patella and tibia of palp, and coxae and trochanters of legs. Body with longitudinal stripes of white scales (Figs 90-91).
Female (focal specimen: paratype, specimen NA13-6083, Figs 88, 89, 93, 94). Carapace length 2.4; abdomen length 2.7. Structure of body typical for
Pellenattus
. Central pocket not on a raised sclerotized mound (it is in
Pellenes peninsularis
). Openings posterior to central pocket (Fig. 86), as in
Pellenes levii
(
Lowrie and Gertsch 1955
, figure 29). Colour paler than male, with more distinct chevrons on the abdomen. Clypeus white except black patches below AME (Fig. 93).

Natural history.
Collected at fairly high elevation on open ground with scattered small rocks, sticks and sparse vegetation (Fig. 98).
