Palp: GnathocoxaSerrula present. Tibia - retrolateral tibial apophysis - characteristicsretrolateral process - RTA. dorsal serration indistinct but present. base of RTA distinctly wider than distal section (consider also retrolateral view). RTA in ventral view medium-sized in width (between 3x longer than broad and 4.5x). RTA medium-sized in length. RTA in retrolateral view with slight ventral orientation (less than 10° angle). Tibia - ventral bump - sizeabsent or at least not recognisable as such. Tibia - ventral bump - characteristicsabsent. Cymbium: General shapeelongated. Scopula lengthmoderate or short (covering less than distal 1/2 of dorsal cymbium). Presence of prominent ridges or extensions ventrally absent. Tegulum: Widthtegulum as broad as cymbium. General shapeelongated. Shape of proximal halfproximal tegulum lobe absent. Special structureswithout special structures. Sperm duct - locationoccupying clearly more than retrolateral half and at most 3/4. Sperm duct - shapeshape not recognisable, as only parts of sperm duct visible through tegulum surface. Median hematodocha - presencepresent. Terminal hematodocha - presencepresent. 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 sizeextremely small (width less than 1/4 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 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 > 3/4 to < 1x the width of central section. General structurewithout or with 1-3 (at most) longitudinal ridges. very short, shorter than 1/3 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. Special structuresickle-shaped. distally pointed. without apohysis (apophyses). Legs: Peculiaritieswith fringe hairs on tibiae and metatarsi of leg III (and legs I-II; but there maybe less distinct). Colourationdark red-brown or brown with few lighter annulations, mainly at proximal articles and tarsi. Opisthosoma: Colourationthree bands; AM broadest; C second broadest (but only slightly narrower than AM), without dark chevron; PM narrowest. Ecology: Geographical DistributionSouth America.

Field - widthclearly broader than long. Window - presencepresent. Window - shape(approximately) round (length / width < 1.1). without transversal division. anterior 1/3 of epigynal window narrower than posterior 1/3.
