TYPE: Male holotype from Mill Valley , Marin Co. , California (June 1951; D. Hardy), deposited in AMNH.
ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.
DIAGNOSIS: Males resemble those of T. humboldt and T. costa but can be distinguished by having the third most ventral prong of the tibial apophysis notched (fig. 79); females have a relatively narrow, ovoid epigynal septum (fig. 80).

Leg spination: femora: I p0-3-1, r1-2-1; II r0-2-1; III r1-1-2; IV r0-1-2; tibiae: I, II d1-0-1, v4-4-4, r1-1-0; III r0-1-1; metatarsi: I, II p1-1-0, r1-1-0; III p1-2-2; IV r1-2-1. Embolus prolaterally expanded near tip, distally narrow; median apophysis with only tiny subdistal projection; most ventral prong of tibial apophysis triangular, middle prong relatively short, distally incised, dorsal prong distally narrowed (figs. 77–79).
FEMALE: Total length 11. Coloration as in T. californicus . Leg spination: femora: I–III r1-1-2; IV p1-2-1, r0-1-2; tibiae: I p1-0-0, v4-4- 4, r1-0-0; II d1-0-0, p0-1-1, v4-4-4, r1-1-0; III r0-1-1; metatarsi III p1-2-2.
