Type Material

 

            Holotype: “Male holotype, male paratype, and female allotype all form Novato, Marin County, California; holotype, June 10, 1965, M. A. Rentz; paratype, May 30, 1957, Frank Crimmers; allotype, July 25, 1960, E. L. Kessel, all deposited in the CAS” (Muma & Brookhart, 1988, p. 29). 

 

            Measurements: “Males (3) variable in size; CP varies from 7.1-10.4 (mean 8.2). Legs short; A/CP varies from 5.7-6.00 (mean 5.9). Fondal notches only about half width of base of fixed cheliceral finger and wider than long; fondal length/width ratio varies from 0.73-0.75 (mean 0.74)” (Muma & Brookhart, 1988, 30).

“Female allotype CP 13.5; A/CP 4.89, no mesal tooth on movable cheliceral finger” (Muma & Brookhart, 1988, p. 30).

 

            Ctenidia Description: “7-12 long, slender, post-stigmatic ctenidia…holotype has 12 long slender post-stigmatic ctenidia (fig. 97), one paratype has 11, another 9, and another only 7, slightly shorter ctenidia (mean 9.7)” (Muma & Brookhart, 1988, p. 30).

            

            Operculum Description: “Female distinguished by gradually enlarged distal ends of anterior opercular lobes, small convex-sided posterior opercular notch and wide, irregularly bowed, vulvular opening extending to posterior ends of posterior opercular lobes…Opercula 2.2 times wider than long with anterior lobes distinctly enlarged distally; posterior opercular notch convex along mesal margins and occupying 28% of opercula (fig. 98)” (Muma & Brookhart, 1988, p. 30).

            

            Chelicerae Description: “Males distinguished by short, rounded, blade-like, dorsal process peaked over distal fourth of fondal notch; fondal notch much narrower than base of fixed cheliceral finger and distinctly wider than long; closely spaced intermediate teeth of movable cheliceral finger with abruptly elevated anterior lobe…Either no or an indistinct mesal tooth on. Movable cheliceral finger which also has an indistinct ventral notch from lateral view (fig. 95)” (Muma & Brookhart, 1988, p. 30).

 

Diagnosis: “The relationships of this species to others of the series will be uncertain until the females of pyriflora have been identified. This variable sized species may prove to be two or more species when more collections are available from northern California” (Muma & Brookhart, 1988, p. 30).
