Type material. U.S.A.: California: Holotype male. Colusa County, two miles northwest of Fouts Springs, 17.x.1955, Schuster, (AMNH) . Paratypes. Colusa. 1♂ 4♀, 2 mi. NW of Fouts Springs, 17.x.1955, Schuster, (AMNH); Lake, 1♂, Paul Hoberg Airport, nr. Howard Springs, 21.ii.1954, no collector (CAS); Mendocino. 2♀, 4.2 mi. S of Piercy, 17.ii.1967, V . D. Roth (CAS) .

Etymology. The specific name is taken from the Latin for “wayfarer” and refers to the resemblance of the patellar apophysis in dorsal and retrolateral views to the universal hitchhiker's thumb gesture.

Diagnosis. The male of C. viator spec. nov. is diagnosed by the form of the patellar apophysis (Figs 43–44) and the proximal arm of the tegular apophysis (Figs 45–46, 48) and is discussed in the diagnoses of C. chauliodous and C. somesbar .

The female of C. viator spec. nov. is distinguished by the small, parenthesis-like atrial openings (Figs 37–30) and the reduced vulval ducting (Figs 38–39); these characteristics are discussed in the diagnoses of C. chauliodous, C. lockeae spec. nov., C. septatus, and C. somesbar .

Description. As in diagnosis. Other descriptive characters are presented here. Ventral tibia I macrosetae 2–1p(or 0)–2–1p–0. Femora very lightly banded ventrally in some specimens.

Male (n=3). Patellar apophysis (Figs 43–44, 47) longer than width of patella; tip angular and arched dorsally; up to six peg setae with usually three on tip and one, slightly larger, isolated near middle of patellar apophysis.

Measurements (n=3). CL 2.10, 2.18, 2.40; CW 1.55, 1.65, 1.80; SL 1.05, 1.09, 1.20; SW 0.99, 1.05, 1.11. Holotype largest specimen.

Female (n=6). Vulva (Figs 38–39) heavily sclerotized with very thick walls; spermathecal stalks very short, nearly linear, not contiguous; spermathecal bases relatively small. Measurements (n=4). CL 2.05–2.23 (2.15), CW 1.38–1.50 (1.45), SL 1.03–1.12 (1.07), SW 0.98–1.04 (1.00). Distribution and natural history.
