Original description
Muma, 1962: 18-21, figs 20-25 (as Therobates adreasana):

males: Total length, 13.0 to 16.0 mm.

                            LENGTH         WIDTH
Chelicerae         3.0 -3.7 mm     1.2-1.5 mm.
Propeltidium    1.5-1.7              2.3-2.8
Palpi                   13.0-16..0         -              
1st legs               9.5-12.0            -
4th legs              15.5-20.5          -

       Holotype larger.
       Color in alcohol light to straw yellow, with dusky purplish markings as follows: eye tubercle dark, propeltidium dusky except for a light area on each side of eye tubercle and a light, median, ovate area; mesopeltidium, metapeltidium, and abdominal tergite irregularly marked; palpi dusky on tarsi, metatarsi, tibiae, and apical ends of femora; legs dusky on apical ends of femora and basal ends of tibiae. Malleoli white.
       Dentition of chelicerae somewhat variable but following general pattern of figures 20 and 21. Movable finger with principal tooth large; two minute intermediate teeth located on and at base of principal tooth; anterior tooth replaced by a rounded elevation, margin of which armed with nodules forming the dorso-ectal edge of mesial groove at tip of finger; mesial tooth absent. Fondal notch obscure, somewhat narrower than width of fixed finger and bearing two or three denticules. Fixed finger gradually tapered from base to tip which is lightly hooked downward; ventral margin of finger bearing aborted teeth which give it a
dentate profile.
       Mesoventral groove of fixed finger distinct apically but indistinct basally, apparently extending three-fourths of length of finger. Flagellum complex consisting of dorsal row of striate bristles, mesial row of plumose bristles that become striate apically, and basal group of tubular bristles. Mesial plumose bristles of movable finger extending nearly to apical end of articulation area.
       Eye tubercle situated on anterior margin of propeltidium. Eyes separated by less than a diameter. Propeltidium wider than long by a ratio of 1 to 1.5.
       Metatarsus, tarsus, and tibia of palpus sparsely provided with large cylinder bristles below and short fine ones above, as well as usual long, slender spines. Metatarsus of palpus without scopula and about four times as long as tarsus.
       First post-spiracular abdominal sternite provided with two long slender ctenidia that extend well beyond anterior margin of succeeding sternite (fig. 22).

FEMALE ALLOTYPE: Total length, 20.0 mm.

                            LENGTH         WIDTH
Chelicerae         5.6 mm             2.0 mm.
Propeltidium    2.3                     3.8
Palpi                   13.0                   -              
1st legs               17.0                   -
4th legs              Fragmented    -

     Color and markings in alcohol same as in males except dusky markingssomewhat fainter.
       Dentition of chelicerae as shown in figures 23 and 24. Movable finger with principal tooth large, one intermediate tooth nearer principal tooth, anterior tooth about two-thirds as large as principal tooth, indistinct serration in front of anterior tooth, and no mesial tooth. Fixed finger with principal tooth large, medial tooth slightly smaller and anterior slightly smaller than medial tooth; one intermediate tooth and one denticule between principal and medial teeth and one intermediate tooth between medial and anterior teeth. Fondal teeth same as in male.
       Structure same as in male except first post-spiracular abdominal sternite provided with only two trace ctenidia scarcely distinguishable from abdominal setal clothing.  Opercula of genital segment as shown in figure 25.

PUBLISHED RECORDS: California: Riverside County - Andreas Canyon, 24 April 1954 (M. Wasbauer), three males (paratypes?) [UCB]; Palm Springs, 20 April 1951 (E. I. Schlinger), one male (paratype?) [UCB].
