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:

CEPHALOTHORAX: Carapace yellow-brown, shiny, finely reticulate; margin, pars cephalica and radiating lines lightly suffused with dark gray; trident mark present. Sternum strongly suffused with dark gray. Clypeus height 2.5. Chelicerae yellow-brown, excavated; ~ 19 seta-tipped tubercles; promargin three teeth, retromargin three denticles and rounded projections near base of fang. Cheliceral stridulatory organ with ~38 well spaced striae, closer basally. ABDOMEN: Uniformly dark gray. LEGS: Light yellow; leg I total length: 3.29; leg III total length: 2.17; Tm I: 0.22, Tm IV: absent. GENITALIA: Palpal retrolateral tibial apophysis well sclerotized, with small pointed tip; dorsal tibial apophysis with rounded tip, smooth, not strongly sclerotized; two retrolateral and one dorsal trichobothria (
Fig. 246
). Cymbium triangular; glabrous depression present (
Fig 246
); dorsal cymbial tubercle smooth, anvil-shaped; ventral cymbial tubercle elongated, with rounded rugose tip; prolateral notch deep (
Fig. 247
). Paracymbium apically constricted, apical pocket long, anterior pocket short, deep and curved, making a small cover, posterior pocket absent (
Fig. 246
). Embolus tip pointed with rounded prong; ventro-retrolaterally with rows of spines; basally excavated with well sclerotized basal flange; Fickert’s gland elongated, set basally; ventral lamella transparent, pointed; thumb long, reaching beyond the embolus proper, with well sclerotized tip (
Fig. 248
). Embolus proper set basally (
Fig. 248
). Anterior terminal apohysis long and narrow with long protrusions; posterior terminal apophysis small with serrated tip and a large basal prong; lamella characteristica with bifid, wellsclerotized tip (
Fig. 249
).
