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 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 more or less parallel with longitudinal axis of palp. 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 - sizevery short and indistinct. Cymbium: Presence of prominent ridges or extensions ventrally absent. Tegulum: Widthtegulum narrower than cymbium. Shape of proximal halfproximal tegulum lobe present. 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). 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 point10 o´clock-position. 11 o´clock-position. 12 o´clock-position. Direction of distalmost sectionprolatero-distally (with between 11° and 50° angle from longitudinal axis of cymbium). disto-prolaterally to prolaterally (with at least 51° angle from longitudinal axis of cymbium). width relation - at arising point - subdistallyfrom 2.1x to 2.5x broader. from 2.6x to 4x broader. width relation - subdistally - centrallyfrom > 1/2 to < 3/4 the width of central section. from > 3/4 to < 1x the width of central section. General structurewithout or with 1-3 (at most) longitudinal ridges. very long, more than 1.5x the width of tegulum. with more than 1 1/2 windings . Special structuredistally pointed. distally rounded. tip bent proximo-ventrally. without apohysis (apophyses). Legs: Leg formula3-4-1-2. 3-4-2-1. 4-3-1-2. Colourationcompletely or mainly with dark colour (e.g. dark red-brown) ((hardly with lighter sections, e.g. only tarsi lighter). Opisthosoma: Colourationthree bands; C & PM medially interrupted or at least less distinct; C broadest, but still narrow (< 1/6 OL), without d. chevron; PM very narrow, but still slightly broader than AM, hence, O with large dark field occupying large part of anterior half of O. Distribution: Geographical DistributionSouth America. North America.
