Original description
Muma, 1951: 94-96, figs 174-177 (as Therobates imperialis):

male holotype:  Total length, 21.0 mm. 

                            LENGTH             WIDTH
Chelicerae         4.7 mm                2.0 mm.
Propeltidium    2.3                        3.3
Palpi                   20.0                      -       
1st legs               15.0                      -
4th legs               26.0                     -

           Coloration in alcohol white to light yellow with dusky purplish markings as follows: eye tubercle dark; propeltidium lightly dusky along anterior margin; tarsus and distal end of metatarsus of palpus dark. Malleoli white.
          Cheliceral dentition as shown in figures 174 to 176. Movable finger with principal tooth large, two widely spaced intermediate teeth, of which the basal is larger, a small anterior tooth, a distal tooth-like process that forms the proximal rim of a dorsal cup-like groove at the distal end of the finger, and a distinct mesal tooth. Fondal notch U-shaped, somewhat narrower than the base of the fixed finger and bearing a distinct denticule. Fixed finger broad basally and abruptly narrowed on the distal half in lateral view; in dorsal view it is gradually tapered from base to tip.
            Groove of fixed finger an indistinct series of mesoventral creases and carinae that extends nearly to the base of the finger. Flagellum complex consisting of a dorsal row of simple tubular bristles, a mesal row of lightly curved, weakly plumose bristles, and a basal group of simple tubular bristles. Mesal setae of movable finger plumose on the basal twothirds of the articulation area.
            Eye tubercle situated on anterior margin of propeltidium. Eyes separated by slightly less than one diameter. Propeltidium wider than long by a ratio of 1 to 1.4.
             Metatarsus, tarsus, and tibia sparsely provided with large cylinder bristles below and short, fine ones above as well as the usual long slender spines. Metatarsus of palpus without scopula and about three times as long as tarsus.
              First post-spiracular abdominal sternite provided with four long, slender ctenidia, of which the middle pair is shorter.
