Agyneta danielbelangeri new species

Figs 246–249, map 17

Type material: Male holotype from Canada, Alberta, Waterton Lakes National Park, 20-28 June 1980, meadow with willows, edge of beaver pond, I. M Smith (CNC). EXAMINED.

Etymology: The specific name is a patronym in honor of Daniel Bélanger, a Québécois author-composer and singer, for his music and poetry that accompanied countless hours of spider studies.

Diagnosis: Males are diagnosed from all other Agyneta species by their wrench-shaped lamella characteristica (Fig. 246). From A. fratrella and A. pistrix by their smaller dorsal cymbial tubercle (Fig. 247).

Description: Male: Total length 1.56; carapace length 0.76, width 0.64.
