Original description
Rowland, 1974: 1-6, figs 1-5:

         Description.- The following description, except for the last paragraph under this heading, pertains to the males of this species.
         Coloration in alcohol purplish brown, chelicerae and pedipalps paler; dorsal sclerotized parts of exoskeleton darkly mottled, with membranous areas paler; eye tubercle very dark (Fig. 1); ventral surface of appendages becoming darker posteriorly, each one paler proximally; malleoli pale purple, slightly darker distally.
         Dentition of chelicerae as in Fig. 2. Movable finger with principal tooth large, intermediate tooth much smaller, anterior tooth even smaller (in some individuals anterior tooth only barely discernible), and mesal tooth missing; distolateral aspect with cup-shaped slot, subdistally flattened in a vertical plane (Figs. 3 and 4). Fondal notch shallow, vaguely U-shaped, about as wide as base of fixed finger, with a single, minute denticle; fondal teeth occurring in two rows, graded laterally I>II >III>IV, and mesally I>III>II>IV; first lateral fondal tooth large, with small accessory tooth on dorsal side, fourth mesal fondal tooth minute, but somewhat larger than denticle on margin of movable finger socket. Fixed finger slightly deflected distally; groove an indistinct mesoventral hollow becoming indistinguishable about two-thirds way to base. Flagellum complex, with apical bristles of dorsal tubular-striate series more distinctly pronounced apically; apical plumose bristle typical, not conspicuously, but somewhat, enlarged and flattened.
         Eye tubercle located on anterior margin of propeltidium, with eyes separated by slightly more than one diameter. Propeltidium wider than long by ratio of 1.4 to 1.
         Femur, tibia, metatarsus, and tarsus of pedipalps sparsely provided with large cylinder bristles, which become shorter distally. Metatarsus of pedipalps with with scopula of about 45 large papillae.
         First post-spiracular abdominal sternum provided with two short, stout ctenidia, whch do not extend quite half way to the posterior margin of next sternum.
         Females differ from males in the following respects: dentition of fixed finger typical of females of genus; movable finger of chelicerae much different from that in males, with larger principal and apical teeth, two smaller intermediate teeth, and several minute denticules beyond apical tooth; genital operculum with pair of vaguely triangular plates (Fig. 5).
