Bennett in Copley et al. 2009: 387, figs 79–84. World Spider Catalog 2021.

Type material examined. U.S.A.: California: Holotype male. Tuolumne County, Fox Gulch, 1.5 miles north of Columbia , 2200’, 6.xii.1986, D. Ubick ( CAS) . Paratypes: Specimens (including one non-paratype female) and locality data in Copley et al. (2009).

Notes. Camp Connell is in Calaveras County, not El Dorado County as recorded in Copley et al. (2009).

Other material examined. U.S.A.: California: Amador. 1♀, 3 mi. W of Volcano , 25.iii.1995, D. Ubick ( CAS) .

Diagnosis. Among the males of the consocius group species, C. vulpinus is only likely to be confused with C. pan spec. nov. Distinguishing the males of these two species is discussed under the diagnosis of C. pan spec. nov. Among the females of the consocius group, the female of C. vulpinus is only likely to be confused with the other species which lack U-shaped copulatory ducts: C. ubicki spec. nov., C. penedentatus , C. opulentus spec. nov., C. pan spec. nov., and C. simplex . The females of C. vulpinus and C. pan spec. nov. are very similar; distinguishing them is discussed under the diagnosis of the latter. The females of the other four species are more easily distinguished; separating females of C. ubicki spec. nov., C. opulentus spec. nov., and C. simplex from females of C. vulpinus is discussed under the diagnoses of those species. Females of C. vulpinus and C. penedentatus are easily separated by atrial morphology: broad in C. vulpinus ( Fig. 40 View FIGURES 37–41 ) versus very small in C. penedentatus ( Figs 46–47, 49–50 View FIGURES 46–51 , 52 View FIGURES 52–54 ).

Description. See Copley et al. (2009).

Distribution and natural history. Western slopes of the south central Sierra Nevada region of eastern California in Amador, Calaveras, and Tuolumne Counties ( Fig. 86 View FIGURE 86 ). A very rarely encountered species known only from the holotype male, collected in December, and four individually collected females.
