In addition to the genus diagnosis, the following features characterize the species:

MALE

Body: MarkingsOpistosoma with dark or bright spots . basic colouring dark. Carapace: ColourationLaterally with light bands. Eyes: AERdorsal edge recurve. Labium: Lengthlonger than wide. Palp: GnathocoxaCorner present. Tibia - retrolateral tibial apophysis - characteristicsdorsal serration indistinct but present. base of RTA not or not distinctly wider than distal section. RTA in ventral view slim. RTA long. RTA in retrolateral view more or less parallel with longitudinal axis of palp. RTA in retrolateral view without bent (or just indistinct bent). Tibia - ventral bump - sizelong (at least 1.5x as long as width of sperm duct, sometimes extending beyond lateral margin of tibia in ventral view). Tibia - ventral bump - characteristicsvery large (extending prolateral margin of tbia in ventral view). Cymbium: Presence of prominent ridges or extensions ventrally present. Tegulum: Widthtegulum narrower than cymbium. Shape of proximal halfproximal tegulum lobe absent. 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 and distal loop equal in size. Embolus: Base positionin prolateral half of tegulum, but not reaching prolateral margin, between central and distal section of tegulum. Base circle sizemedium-sized. large (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 point6 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 - subdistallyfrom 2.1x to 2.5x broader. width relation - subdistally - centrallyfrom > 1/4 to < 1/2 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. massive (centrally almost as broad or broader than width of sperm duct). Special structuredistally irregularly bifurcated. S-shaped. distally distinctly bent retrolaterally. tip bent retrolaterally (tip may be very fine and light). without apohysis (apophyses). Legs: Leg formula3-4-2-1. 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 & PM longitudinally connected by large and broad light patch. Distribution: Geographical DistributionSouth America.
