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 long. 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 - sizeshort (between 0.5x and 0.8x the width of sperm duct). Tibia - ventral bump - characteristicspresent. inconspicuous. 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 narrower than cymbium. General shapeelongated. Shape of proximal halfproximal tegulum lobe present. Proximal lobe - positionstill retrolaterally, but slightly shifted centrally. Proximal lobe - size rel.medium-sized. Proximal lobe - shapeprolaterally with very flat extension. Special structureswith flat triangular lobe directed distally. Sperm duct - locationoccupying clearly more than retrolateral half and at most 3/4. Sperm duct - shapedouble-stacked S-shaped, with proximal loop smaller than distal. Median hematodocha - presencepresent. Terminal hematodocha - presencepresent. Embolus: Base positioncentro-distally (or even retrolatero-distally). Base circle sizemedium-sized. Base - special structureswith longitudinal ridge (division) leaving a basal part prolaterally (but sometimes not clearly recognisable!). Arising point6 o´clock-position. 7 o´clock-position. Direction of distalmost sectionprolatero-distally (with between 11° and 50° 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. short, between 1/3 and 1/2 the width of tegulum. with less than 1/2 winding. without distinct embolic lamella over entire embolus length. without apophysis. in ventral view subdistally distinctly narrower than proximally. differently shaped (not hose-shaped, not filiform, not massive) (e.g. irregular shape or...) . Special structuresickle-shaped. distally pointed. tip bent proximo-ventrally. without apohysis (apophyses). Legs: Leg formula4-3-2-1. Tarsal ClawsI: present. II: present. III: present. IV: present. 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 several lighter annulations, mainly at proximal articles and tarsi, but also at distal sections of tibiae and/or metatarsi. dark 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. Spination pattern: Femur I1-5-0-0. Femur II1-6-0-0.
