Diagnosis. This species is distinguished from other species of the E. (En.) canaster species group by a single paint brush-like preapical ventral lobe on the male hind femur, single digitiform basal process on the male hind tibia, and length of the dorsal setae on the male hind tibia slightly longer than width of tibia ( Figs 124–126 View FIGURES 121–126 ).

Geographical distribution and seasonal occurrence ( Fig. 130 View FIGURES 129–130 ). This species is only known from a single damaged male and two females collected in Marysville, British Columbia in July .

Nuptial gift presentation. Form unknown.

Remarks. This species was left undescribed because only a single male specimen is known, which is missing the left hindleg and the right hindleg is strongly contracted, obscuring clear view of the ventral processes. It appears to be a unique species in the E. canaster group based on the hindleg, but the male terminalia ( Fig. 127 View FIGURES 127–128 ) is rather similar to E. chillcotti sp. nov. This un-named species is included in the identification key to males of the species of E. ( Enoplempis ) from the Rocky Mountains westward.
