Type material examined. U.S.A.: California: Holotype male. Santa Clara County, 2 miles north of Holy City, Highway 17, 6.xii.1966, V. D. Roth & Ferguson ( CAS) . Paratypes: Specimens and locality data as in Copley et al. (2009).

Other material examined. U.S.A.: California: Monterey. 2♀, San Juan Grade Rd. , 5.i.1997, D. Ubick ( CAS); Santa Cruz. 2♀, Felton, 24.ii.1985, V . D. Roth & B. Roth ( CAS) .

Diagnosis. Both sexes of C. penedentatus are distinctive and unlikely to be confused with any of the other species in the consocius group. The male is diagnosed by its elongate patellar apophysis (as long as the width of the patella) with very few peg setae ( Fig. 43) as well as the posteriorly directed basal flange, longitudinal ventral keel, and acuminate slightly twisted tip of the proximal arm of the tegular apophysis ( Figs 44–45). The female is diagnosed primarily by the very small, transverse, medially located atrium ( Figs 46–47, 49–50, 52) and secondarily by the membranous copulatory ducts extending contiguously or in close proximity from the atrium to the anterior margin of the vulva before diverging and heading laterally and posteriorly to merge with the spermathecal heads and stalks ( Figs 47–51, 53–54).

Description. See Copley et al. (2009).

Distribution. Coastal central California west of San Francisco Bay south to Monterey Bay in San Mateo, Santa Clara and Santa Cruz Counties ( Fig. 86). The holotype, the single known male specimen of C. penedentatus , was collected in December.
