Carapace (Figs 1, 2) length/width 1.15; flat, cephalic area slightly raised, thoracic furrows shallow and wide. Fovea: 1.0 wide; deep, straight. Carapace with many short, thin setae, interspersed with some longer and thicker setae; border with abundant long and thick setae pointing out, increasing in number towards posterior angles. Clypeus 0.3, frontal margin bearing 9 thick, long, erect setae (Fig. 3). Eye tubercle (Fig. 3) length 0.9, width 1.9, with sparse thin setae separating eyes of both sides and thicker, longer setae at the anterior and posterior borders. AME elliptical, with a milky lens, yellowish brown background, no retina or eye pigments visible. Left AME larger than right one. All other eyes (ALE, PME and PLE) fused in an asymmetrical, crescent shaped, lateral eye mass, with irregular borders, covered by a thin lens, with uniform white background. Right lateral eye mass thinner, shorter and with a more pronounced notch than the left one. Eye row curvature not definable, but AME anterior border a little advanced in relation to anterior border of lateral eye mass (Fig. 3). Right AME 0.3,

0.3, right lateral eye mass 0.6 long. Chelicerae (Fig. 2) length/carapace length 0.41, 11 and 12 teeth on promargin, on the left and right chelicera, respectively. Maxillae (Figs 5, 6) length\width: 2.1. Cuspules: 36 spread over ventral inner heel. Lyra at the ventral side of the maxilla, asymmetrical, formed by 4-5 modified thick, long setae, increasing in size from basal to distal one, strongly curved at apical portion, apex just tapering to a point. Right lyra with just 4 setae, left lyra with 5 large setae and a very small, thinner basal one. Thick, erect, regularly curved setae (Fig. 6, arrow) placed distally and a bit internally in relation to lyra, in number of 4 at the right maxilla and 3 at the left one. Labium: length/width 0.8, no cuspules. Labio-sternal groove deep, with elongated sigilla. Sternum (Fig. 5) length (up to labium border) 5.3, width 4.7. Posterior angle in a blunt point, not separating coxae IV. Sigilla: three pairs, elliptical, increasing in size backwards, all far from margin by its own size. Palp long, without spines at retrolateral side, one prolateral spine at distal third of femur, 2 prolateral spines at tibia, distal one longer and thicker. Tibia: length 6.3, thin and long, with similar diameter throughout, length/width 9.1. Leg formula 4123. Legs covered with more abundant short, thin, horizontal black setae and with

longer, thicker, erect black setae. Leg I with modified tibia and metatarsus, forming a retrolateral clasping mechanism (Figs 10-11). Tibia I with a retrolateral distal spur (or apophysis) relatively long, somewhat curved, blunt, bearing a curved, pointed spine at tip. Metatarsus I with small retrolateral tubercle, situated distally to basis of first ventral spine. Tarsal trichobothria much longer than covering setae, placed in a row along the midline of dorsal face. Scopula undivided, covering distal half of metatarsus I and distal third of metatarsi II-III; all tarsi covered with scopula throughout

Claws: ITC without teeth. Teeth at STC: leg I inner row 4-5, outer row 10-13; leg II inner row 4-5, outer row 10-12; leg III inner row 3, outer row 9-11; leg IV inner row 2-3, outer row 7-10. Bulb (Figs 7-9) globose, with moderately long embolus, a little longer than basis (ratio 1,3). Bulb with prolateral face convex, gently and uniformly curved, retrolateral face convex at basis and concave at end portion, due to an abrupt curve, forming a strong constriction of bulb near basis of embolus. Embolus with a broad

In frontal view, embolus placed at prolateral margin of bulb, slightly curved initially, straight through most of its length, with apex bent retrolaterally (Fig. 9). Also, there is a strong bulge of bulb near embolus basis at same view.
