Embolus: Base positionin prolateral half (or, depending on the size, prolateral 2/3, 3/4, etc.) of tegulum, in line with (or even extending) the prolateral margin; at distal section. Base circle sizelarge (width between 2/3 and 3/4 the width of tegulum). very large. Base - special structuresSpecial structures at/ on embolus base absent (except for indistinct ridges or flat bulges that are often recognisable). Arising point5 o´clock-position. 6 o´clock-position. 7 o´clock-position. 8 o´clock-position. Direction of distalmost sectiondistally to minimally prolatero-distally (not more than 10° angle from longitudinal axis of cymbium). width relation - at arising point - subdistallyat most 2x broader. width relation - subdistally - centrallyfrom > 1/2 to < 3/4 the width of central section. Shapecircular curved. bent counterclockwise. General structurewith more than 3 longitudinal ridges. long. with less than 1/2 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. quite broad and hose-shaped. Special structuredistally regularly bifurcated. S-shaped. distally truncated. without apohysis (apophyses). Legs: Leg formula3-4-2-1. 4-3-2-1. Colourationcompletely or mainly with dark colour (e.g. dark red-brown) ((hardly with lighter sections, e.g. only tarsi lighter). Opisthosoma: Colourationthree bands; AM broadest; C second broadest, with dark chevron; PM narrowest. Distribution: Geographical DistributionSouth America.
