MALE

Palp: GnathocoxaCorner present. Tibia - retrolateral tibial apophysis - characteristicsdorsal serration absent. base of RTA not or not distinctly wider than distal section. RTA in ventral view very slim. RTA very long (longer than width of tegulum). RTA in retrolateral view with slight ventral orientation (less than 10° angle). RTA in retrolateral view without bent (or just indistinct bent). Tibia - ventral bump - sizemedium-sized (as long or about as long as width of sperm duct). Tibia - ventral bump - characteristicsmoderately conspicuous. Cymbium: Presence of prominent ridges or extensions ventrally absent. Tegulum: Widthtegulum narrower than cymbium. Shape of proximal halfproximal tegulum lobe present. proximal tegulum lobe absent. Proximal lobe - positiondistinctly shifted centrally. Proximal lobe - size rel.broad. Proximal lobe - shaperegularly rounded. Special structureswith (fine) transversal ridge (often at distal half at the area of the border between embolic division and tegulum). Sperm duct - locationoccupying retrolateral half of tegulum or slightly more. Sperm duct - shapedouble-stacked S-shaped, with proximal loop larger than others. Embolus: Base positionin 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 sizelarge (width between 2/3 and 3/4 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. width relation - subdistally - centrallyfrom > 1/4 to < 1/2 the width of central section. General structurewith more than 3 longitudinal ridges. without or with 1-3 (at most) longitudinal ridges. long. with less than 1/2 winding. without distinct embolic lamella over entire embolus length. with apophysis. in ventral view subdistally not narrower or narrower, but not distinctly narrower than proximally (more than 1/7 as broad. massive (centrally almost as broad or broader than width of sperm duct). Special structureS-shaped. distally truncated. tip bent retrolaterally (tip may be very fine and light). with more than two apohyses. Legs: Leg formula3-4-2-1. Colourationdark red-brown or brown with few lighter annulations, mainly at proximal articles and tarsi. Opisthosoma: Colourationthree bands; AM broadest; C second broadest, with dark chevron; PM narrowest. Distribution: Geographical DistributionSouth America.
