Base circle sizemedium-sized. Base - special structuresSpecial structures at/ on embolus base absent (except for indistinct ridges or flat bulges that are often recognisable). Arising point6 o´clock-position. 7 o´clock-position. 8 o´clock-position. Direction of distalmost sectiondisto-prolaterally to prolaterally (with at least 51° angle from longitudinal axis of cymbium). width relation - at arising point - subdistallyfrom 4.1x to 7.5x broader. width relation - subdistally - centrallyfrom > 1/4 to < 1/2 the width of central section. Shapecircular curved. bent counterclockwise. General structurewithout or with 1-3 (at most) longitudinal ridges. medium-sized, between 1/2 and 1x the width of tegulum. with more than 1/2 winding but less than 3/4 winding. without distinct embolic lamella over entire embolus length. without apophysis. in ventral view subdistally not narrower or narrower, but not distinctly narrower than proximally (more than 1/7 as broad. narrow (centrally between 1/4 and 1/3 the width of sperm duct). narrow to medium-sized and hose shaped. Special structuresickle-shaped. distally pointed. without apohysis (apophyses). Legs: Leg formula3-4-1-2. 3-4-2-1. Colourationdark red-brown or brown with several lighter annulations, mainly at proximal articles and tarsi, but also at distal sections of tibiae and/or metatarsi. dark red-brown or brown with few lighter annulations, mainly at proximal articles and tarsi. Opisthosoma: Colourationthree bands; AM broadest; C second broadest (but only slightly narrower than AM), without dark chevron; PM narrowest. Distribution: Geographical DistributionSouth America.
