ETYMOLOGY: The specific name is a noun in apposition taken from the
type
locality.
DIAGNOSIS: Males and females have not been collected together, and it is possible that the females treated here as
T. tulare
are actually those of
T. icenoglei
, and vice versa. Males resemble those of
T. heberti
but differ in having the tibial apophysis with a distally wider middle prong (fig. 54); females differ from those of
T. heberti
in having a posteriorly narrowed epigynal septum (fig. 55).
MALE: Total length 16. Coloration as in
T. californicus
. Leg spination: femora: I p0-4-1, r1-2-1; II r1-2-1; III p1-1-2, r1-2-2; IV p1-2-1; tibiae: I v6-6-4, r1-2-0; II d1-0-1, v6-6-4, r1-2- 0; III d1-0-0, p1-1-2, r0-1-1; IV r1-0-2; metatarsi: I, II p1-1-0, r1-1-0; III p1-2-2. Embolus twisted near base, distally narrow; median apophysis with subdistal and retrolateral projections; middle prong of tibial apophysis bifid but not deeply incised, dorsal prong large, wide, flattened (figs. 52–54).
FEMALE: Total length 13. Coloration as in
T. californicus
. Leg spination: femora: I r1-2-1; II p1-1-2, r1-1-2; tibiae: I d1-0-0, v4-4-4, r1- 1-0; II d1-0-1, v4-4-4, r1-1-0; III r0-1-1; metatarsi: II r1-1-0; III p1-2-2. Epigynal septum wide but short, posterior portion restricted to narrow, triangular bulge; posterior ducts oblique, spermathecae narrow (figs. 55, 56).
