AERdorsal edge recurve. PERequidistant between anterior and posterior margin of carapace. PER - AER widthPER < AER. AMEseparated of each other. touch each other. ALEseparated from AME. PMEsmall, < 1/3 as ALE. equidistant between ALE & PLE. PLEPLE = ALE. Labium: Lengthlonger than wide. Sternum: Length : width ratio< 2 : 1. Anterior borderwider than Labium. Shapeshield-shaped. Palp: GnathocoxaSerrula present. Tibia - retrolateral tibial apophysis - characteristicsretrolateral process - RTA. dorsal serration indistinct but present. base of RTA not or not distinctly wider than distal section. RTA in ventral view medium-sized in width (between 3x longer than broad and 4.5x). 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 - 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 narrower than cymbium. General shapeelongated. 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 - 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, in line with (or even extending) the prolateral margin; at distal section. Base circle sizelarge (width between 2/3 and 3/4 the width of tegulum). Base - special structureswith longitudinal division (ridge) dividing embolus base in a basal and a prolatero-distal part (prolatero-distal part in retrolateral view distinctly protruding from distal part of tegulum). Arising point7 o´clock-position. 8 o´clock-position. 9 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. General structurewithout or with 1-3 (at most) longitudinal ridges. very long, more than 1.5x the width of tegulum. with distinct embolic lamella (longitudinally associated hyaline membrane (homologous to conductor?), 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 to medium-sized and hose shaped. Special structuresickle-shaped. distally pointed. without apohysis (apophyses). Legs: Leg formula3-4-2-1. 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 few lighter annulations, mainly at proximal articles and tarsi.
