(Muma): Muma, 1970a: 35; Muma, 1976: 20; Brookhart and Brookhart, 2006: 319

HOLOTYPE: United States. California: San Bernardino County - Mule Canyon, Calico Mountains, 17 March 1955 (P. D. Hurd), 1 male (holotype), beating Larrea; 11 March 1955 (Hurd and Wasbauer), 1 female (also reported as holotype).  Deposited in the American Museum of Natural History.  Muma (1962) also refers to "female paratypes from the same locality, taken in the same manner on the same date (M. Wasbauer)", and reports them as deposited in the collection of the "University of California".

Original description
Muma, 1962: 21-24, figs 26-29 (as Therobates larreae):

male holotype: Total length, 9.5 mm.

                            LENGTH         WIDTH
Chelicerae         2.4 mm             0.9 mm.
Propeltidium    1.4                     1.5
Palpi                   11..0                   -              
1st legs               8.0                      -
4th legs              14.0                    -

       Color in alcohol white to light yellow, with dusky purplish markings as in T. andreasana except mesopeltidium, metapeltidium, and abdominal tergites light and there are two faint dusky stripes on chelicerae.
       Dentition of chelicerae as shown in figures 26 and 27. Movable finger evenly curved from base to tip, principal tooth small, intermediate and anterior teeth missing, apical sixth of finger formed into mesially facing, cup-like structure, mesial tooth absent. Fondal notch obscure and without denticules. Fixed finger lightly curved upward, abruptly narrowed and hooked downward at tip; ventral margin of finger undulate but not bearing aborted teeth.
       Mesoventral groove of fixed finger distinct and occupying most of length of finger. Flagellum complex typical of group, with apical striate and plumose bristles strikingly prominent. Mesial plumose bristles of movable finger restricted to base of articulation area. Eye tubercle situated on anterior margin of propeltidium. Eyes separated by about one diameter. Propeltidium wider than long by a ratio of 1 to 1.1.
       Eye tubercle located on anterior margin of propeltidium, with eyes separated by slightly more than one diameter. Propeltidium wider than long by a ratio of 1 to 1.3.
       Metatarsus, tarsus, and tibia of palpus with usual clothing of cylinder bristles and long, slender spines. Metatarsus without scopula but with two unequal rows of stout spines and about four times as long as tarsus.
       First post-spiracular abdominal sternite with four long, slender ctenidia extending well beyond anterior margin of succeeding sternite (fig. 28). Middle pair slightly shorter.

FemaleS: Total length, 12.0-13.0 mm.

                            LENGTH         WIDTH
Chelicerae         2.8-3.1 mm      0.9-1.1 mm.
Propeltidium    1.3-1.6              1.6-2.1
Palpi                   8.0-9.0               -              
1st legs               6.0-7.0               -
4th legs              12.0-13.0           -

       Female allotype larger.
       Color and markings in alcohol similar to those of male.
       Dentition of chelicerae similar to that of T. andreasana except there are two intermediate teeth in front of medial tooth of fixed finger.
       Structure similar to that of male except ctenidia on first post-spiracular abdominal sternite scarcely distinguishable from setal clothing.
       Opercula of genital segment as shown in figure 29
