Diagnosis.
Males (
Figs 17–19
) can by distinguished by the combination of tubercles on the carapace surface, an opisthosoma with a chevron pattern and a distinct dorsal posterior sclerotization, a long triangular RTA, and slender, sinuous embolus. Females (
Fig. 16
) can by distinguished by the small anterior hood and the long, forwardly-directed copulatory ducts.
Description.
See Dondale & Redner (1982) for male and female descriptions.
Natural history and habitat.
The range of distribution of this species covers the ecosystems of Cascade Province,
California
Coastal Chaparral Forest Shrub Province and
California
Dry Steppe Province. The combination of wet winters with dry summers produces a distinctive natural vegetation of hard-leaved evergreen trees and shrubs called sclerophyll forest. The vegetation varies between a dense conifer, cedar and hemlock forest, with numerous species of shrubs, sagebrush and grassland communities, to mixed prairie.
Distribution.
Pacific
Coast
from
Washington
