Holotype: Det. Martin H. Muma, 1950; originally identified as Therobates imperialis. "Male holotype from Palo Verde, Imperial County, California, August 17, 1946 (P. Hurd), in the collection at the University of California" (Muma, 1951, p. 96).
Chelicerae Description: "Chelicerae 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" (Muma, 1951, p. 96).
Chelicerae Setae Description: "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 two-thirds of the articulation area" (Muma, 1951, p. 96).
Ctenidia Description: "First post-spiracular abdominal sternite provided with four long, slender ctenidia, of which the middle pair is shorter" (Muma, 1951, p. 96).
Diagnosis: "The unusual development of a cup-like groove at the apical end of the movable finger causes the placement of this species in a separate group within the genus. Otherwise it seems to be a typical Therobates" (Muma, 1951, p. 96).
