V aricition. Males: A comparison of the two small samples of two 
males each indicates rather strong geographic variation. The Oak 
Creek Canyon sample has a markedly larger body size ( CL = 4.8 
mm, 4.9 mm), a proportionately longer pedipalpal patella (CL/ 
PPL = 1.53, 1.64), and darker coloration than the Santa Catalina 
Mountain sample (CL = 3.5 mm, 3.8 mm; CL/PPL = 1 .75, 
1.77)* The conductor tip is proportionately a bit narrower and is 
bent more strongly (Figs. 107-109) in the Oak Creek Canyon males. 
Females: No marked geographic variation occurs in any of the ratio 
characters. The Oak Creek Canyon sample averages larger in body 
size, but the ranges of the two samples overlap. Seminal receptacle 
stalks are more irregularly sinuous in the Santa Catalina Mountain 
sample than in the Oak Creek Canyon sample (Figs. 144-146). The 
two samples show broadly overlapping color variation.

Type specimens and etymology . Holotype male from Grizzly 
Creek Redwoods State Park, Humboldt Co., California, 8 August 
1972 (F. A. Coyle). One male and 14 female paratypes. The 
specific name is a Latin adjective meaning northern. 
Diagnosis. Males: The weakly sclerotized, finger-like extension 
at the tip of the palpus (Fig. 106) is distinctive. The pedipalpal 
patella is proportionately long (Fig. 81), so that appropriate ratios 
from among the following distinguish A. aquilonius from any 
other species (Table 1): PTL/PPL, PPL/PFL, CL/PPL, CL/ 
PSS, SW/PSS. A. aquilonius males are markedly smaller than 
those of coastal A. calif ornicus and some other species (Table 1). 
Females: The following characters best distinguish A. aquilonius 
from similar species: smaller AMD/AMS (Table 2) and more 
strongly coiled seminal receptacle stalks (Figs. 147-148) than in
