TYPE: Male holotype taken at an elevation of 6000 ft at Tahoe City, Placer Co. , California (July 10, 1952; W. Gertsch), deposited in AMNH.
ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.
DIAGNOSIS: Males and females have not been collected together but are matched here on the basis of geography; males can easily be recognized by the tibial apophysis consisting of four prongs (fig. 34), females by the thumbshaped median lobe situated posteriorly on the epigynal septum (fig. 35).
MALE: Total length 8. Coloration as in T. californicus . Leg spination: femora: I r1-2-1; II p2-1-1, r1-1-2; III r1-2-2; IV p1-2-1; tibiae: I, II d1-0-1, v4-4-4, r1-1-0; III, IV r0-1-1; metatarsi: I p1-1-0, r0-1-0; II p1-1-0, r1-1-0; III, IV p1-2-2. Embolus expanded prolaterally just beyond base; median apophysis long, with large, subdistal projection; tibial apophysis with four prongs, only two most distal sharing common base (figs. 32–34).
FEMALE: Total length 19. Coloration as in T. californicus . Leg spination: femora: II, III r1-1-2; tibiae: I, II r1-1-0; III r0-1-1; IV p1-0-1; metatarsi: II p1-1-0, r1-1-0; III p1-2-2.
