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. Chelicera: Base furrow teeth number promarginal2 teeth. 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 - sizevery short and indistinct. Tibia - ventral bump - characteristicsinconspicuous. Cymbium: Presence of prominent ridges or extensions ventrally absent. Tegulum: Widthtegulum as broad as cymbium. Shape of proximal halfproximal tegulum lobe present. proximal tegulum lobe as such absent. Proximal lobe - positionat retrolateral half of tegulum. Proximal lobe - size rel.medium-sized. 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 clearly more than retrolateral half and at most 3/4. Sperm duct - shapedouble-stacked S-shaped, with proximal loop larger than others. 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 sizevery 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. Direction of distalmost sectiondisto-prolaterally to prolaterally (with at least 51° angle from longitudinal axis of cymbium). width relation - at arising point - subdistallyfrom 4.1x to 7.5x broader. width relation - subdistally - centrallyfrom > 1/4 to < 1/2 the width of central section. Shapecircular curved. bent counterclockwise. General structurewithout or with 1-3 (at most) longitudinal ridges. long. 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 distinctly narrower than proximally. 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 irregularly bifurcated. S-shaped. sickle-shaped. distally pointed. distally distinctly bent retrolaterally. tip bent retrolaterally (tip may be very fine and light). without apohysis (apophyses). Legs: Leg formula4-3-2-1. Colourationmoderately dark or light (red-)brown with many lighter annulations. Opisthosoma: Colourationthree bands; AM broadest; AM & C narrower (C < 1/6 OL), without light small stacked chevrons betw. C & PM. Distribution: Geographical DistributionSouth America.
