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, CaliforniaCoastal Chaparral Forest Shrub Province and CaliforniaDry 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 Coastfrom Washingtonsouth to Baja California Norte.   FIGURE 15.  Meriola balcarce, genitalia. a, Female epigyne, ventral view (MACN-Ar 33021); b, vulva, cleared, dorsal view. c, male, left palp, prolateral view (MACN-Ar 33021); d, same, ventral view; e, same, retrolateral view.  New records.   U.S.A.: Washington: King Co.: Seattle, N 47.606210°, W 122.332071°,  8.X.1933, Exline-Peck, 1 female( CAS, CASENT 9059125).  Seattle, N 47.606210°, W 122.332071°,  6.X.1934, M.
