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. Tibia - ventral bump - sizeshort (between 0.5x and 0.8x the width of sperm duct). Tibia - ventral bump - characteristicsmoderately conspicuous. Cymbium: Presence of prominent ridges or extensions ventrally absent. Tegulum: Widthtegulum broader than cymbium (even though minimally broader). 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). 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 sizemedium-sized. Base - special structuresSpecial structures at/ on embolus base absent (except for indistinct ridges or flat bulges that are often recognisable). Arising point7 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 - centrallyeven > than the width of central section. Shapecircular curved. bent counterclockwise. 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 (centrally between 1/4 and 1/3 the width of sperm duct). Special structuresubdistally broadened. distally prolaterally with very fine candle-flame-like protrusion. distally pointed. without apohysis (apophyses). Legs: Leg formula3-4-2-1. Colourationdark red-brown or brown with several lighter annulations, mainly at proximal articles and tarsi, but also at distal sections of tibiae and/or metatarsi. Opisthosoma: Colourationthree bands; AM broadest; C second broadest, with dark chevron; PM narrowest. three bands; AM broadest; C second broadest (but only slightly narrower than AM), without dark chevron; PM narrowest. Distribution: Geographical DistributionSouth America.
