Materials Examined
Type material:Male holotype from Canada, Alberta, Waterton Lakes National Park, Granite Chief Mountain Hwy, 4500ft., 14–28.vi. 1980, interception trap, J.M. Campbell (CNC). EXAMINED.
Etymology
Etymology: The specific name is a noun in apposition taken from the type locality, Waterton Lakes National Park, in Alberta, Canada.
Diagnosis
Diagnosis: Males are diagnosed from all Agyneta by the curved posterior pocket of the paracymbium, creating a large cover (Fig. 104). From A. protrudens by the presence of a conical cymbial ventral tubercle (Fig. 105).
