Embolus: Base positioncentro-distally (or even retrolatero-distally). Base circle sizesmall (width between 1/3 and 1/2 the width of tegulum). Base - special structuresSpecial structures at/ on embolus base absent (except for indistinct ridges or flat bulges that are often recognisable). Arising point8 o´clock-position. 9 o´clock-position. Direction of distalmost sectionprolatero-distally (with between 11° and 50° angle from longitudinal axis of cymbium). width relation - at arising point - subdistallyat most 2x broader. from 2.1x to 2.5x broader. width relation - subdistally - centrallyfrom > 1/2 to < 3/4 the width of central section. 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 to medium-sized and hose shaped. Special structuresickle-shaped. distally truncated. without apohysis (apophyses). Legs: Leg formula1-2-3-4. 1-3-4-2. 4-3-2-1. Colourationdark 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.
