Measurements: Male Holotype: Total Length, 21.0 mm. Chelicerae, 5.7 mm length; 2.5 mm width. Propeltidium, 2.6 mm length; 3.8 mm width. Palpi, 19.0 mm. 1st Legs, 15.0 mm. 4th Legs, 23.0 mm.
Female Allotype: Total Length, 23.0 mm. Chelicerae, 5.7 mm length; 2.5 mm width. Propeltidium, 2.4 mm length; 4.2 mm width. Palpi, 15.0 mm. 1st Legs, 13.0 mm. 4th Legs, 21.0 mm. Female paratype, same measurements.
Ctenidia Description: “there are three straight, flattened ctenidia on the first post-spiracular sternite of the abdomen. Although the holotype carries three ctenidia it is probable that two or four are typical” (Muma, 1951, p. 58).
Operculum Description: “Structure as in scaber (Kraepelin). Specific differences are found in the opercula of the genital segment of the abdomen (fig. 68)” (Muma, 1951, p. 58).

Other Information: “Although this species is described here as new, a comparison of the type with that of geniculatus (Simon) may prove it to be a synonym of that species” (Muma, 1951, p. 58).
