Image(s) of Habitus:

Description: Carapace is brown with a broken light brown to yellow (Kronestedt, 1981), or reddish (Chamberlin, 1908) band down the middle, and continuous lateral bands of similar colour, as well as two light spots behind the eyes. Chelicerae are yellowish brown with black streaks (Dondale & Redner, 1990). Sternum is dark brown with a light, but indistinct median stripe (Kronestedt, 1981), bordered by black lines (Chamberlin, 1908). Abdomen hairy and mottled grayish brown with a pale heart mark (Dondale & Redner, 1990). Legs are light brown and do not have rings, but femora have light longitudinal streaks (Kronestedt, 1981). Palp is distinguished by its stout terminal apophysis, with the conductor situated distal to the basal margin of the apical division, and by its small median apophysis (Dondale & Redner, 1990).

Male Dimensions: A = 3.36 mm  A+B = 6.71 mm  C = 2.41 mm

Description: Colouration as in male, except that the lateral bands on the carapace are wider, and the sides and venter of the abdomen have white pubescence. The epigynum is distinct because of its atrium, which is about as wide as long, and because of its median septum, which has a narrowed anterior part that is quite short, with the anterior margins of the cavity sclerites extending anterolaterally (Dondale & Redner, 1990).

Female Dimensions: A = 3.17 mm  A+B = 6.93 mm  C = 2.27 mm
