TYPES: Male holotype and female allotype from Riverton , El Dorado Co., California (July 11, 1952; W. Gertsch), deposited in AMNH.
ETYMOLOGY: The specific name is a patronym in honor of the collector of the types.
DIAGNOSIS: Males resemble those of T. madera in having the dorsal prong of the median apophysis long and excavated, but differ in having only two projections on the middle prong of the tibial apophysis (fig. 39); females also resemble those of T. madera in having a gradually narrowed posterior projection on the epigynal septum, but have the septum much wider than in that species (fig. 40).
MALE: Total length 16. Coloration as in T. flavescens . Leg spination: femora: I r1-2-1; II r1-1-2; IV p2-1-1; tibiae: I, II d1-0-1, r1-1-0; III p1-0-1, r1-0-1; IV p1-0-1; metatarsi: I, II p1-1-0, r1-1-0; III p1-2-2. Embolus expanded prolaterally just beyond base; median apophysis with large, subdistal projection; middle prong of tibial apophysis bifid, dorsal prong long, ventrally excavated (figs. 37–39).
FEMALE: Total length 18. Coloration as in T. flavescens . Leg spination: femora: II p1-1-1, r1-1-1; III, IV p1-2-1; tibiae: I r1-1-0; II d1-0- 1, r1-1-0; III p1-0-1, r1-0-1; metatarsi: I p1-0- 0; II r0-1-0; III p1-2-2. Epigynal septum very wide, occupying most of epigynal width, with gradually narrowing posteromedian ledge; posterior ducts curved (figs. 40, 41).
