Special structureswith (fine) transversal ridge (often at distal half at the area of the border between embolic division and tegulum).

Embolus: Base positioncentro-distally (or even retrolatero-distally). in prolateral half (or, depending on the size, prolateral 2/3, 3/4, etc.) of tegulum, but not reaching the prolateral margin; at distal section. 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. 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 > 3/4 to < 1x 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 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. narrow to medium-sized and hose shaped. Special structuredistally regularly bifurcated. S-shaped. without apohysis (apophyses). Legs: Leg formula3-4-1-2. 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; AM & C narrower (C < 1/6 OL), with light small stacked chevrons betw. C & PM . Distribution: Geographical DistributionSouth America.
