Carapace 3.92 long, 3.01 wide. Opisthosoma 4.13 long, 2.09 wide. Total, 8.1.
I: 5.27, 1.67, 5.40, 5.40, 3.47, 21.21. II: 5.60, 1.87, 5.54, 5.60, 3.60, 22.21. III: 6.14, 1.74, 6.00, 6.80, 4.20, 24.88. IV: 7.47, 1.94, 7.07, 8.00, 4.60, 29.08. Palp: 1.74, 0.87, 1.54, -, 2.00, 6.15.
Colour. Carapace fawn with strong wide black sash medially from and including all eyes narrowing prefoveally and widening again posteriorly, black flecks laterally on caput, two at caput construction on margin and one subcentrally; opisthosoma dorsally fawn with long wide black sash medially breaking up slightly on posterior edges; venter pallid save for 2 black marks lateral of spinnerets; femora yellow brown with slightly black mottling. Carapace margins with long hoary white hair.
Eyes: Eight in 2 recurved rows; front edge of ALE in base of back edge of AME, likewise in back row. Relative sizes: AME>PME>PLE>ALE. Front width, back width, long, 41:49:32. Sizes: AME, 11; ALE, 6; PME, 8; PLE, 10. AME–AME, 6; AME–ALE, 6; PME–PME, 7; PME–PLE, 0. Chelicerae. Promargin with 3 teeth, retromargin with 2. Sternum pilosity: long white hairs on margins, rest short brown bristles centrally directed, more thickened.
Legs. Very long. Trochanter notches
ca
. x 1.5 wider than deep. STC with 6 long teeth. Tarsi bowed. Scopula thin in bands 1/2–2/3 of metatarsi I–IV; denser but still thin on tarsi I–IV; pseudotufts not dense but extend beyond claws. Spines. I: fe pv1p2d3r4; pa 0; ti p2d3r2v2.2.2; me p1.2r1.1.v2.2. II: fe pv1p3d3r3; pa 0; ti p2d3r2v2.2.2; me p0r1. v2.2. III: fe p4d3r4; pa 0; ti p2d2.1r2v2.2.2; me p1.1.1.1r2.1.1v2.2.1.

, male palpal bulb, cymbium and tibia, scanning electron micrographs: a, bulb, proventral view; b, ventral view.
Spinnerets: PLS and ALS long cylindrical; PLS
ca
. 0.5 x diameter of ALS with conical apical article; PMS smaller cylinders.
Palp. Tibia short with longitudinal ridge on prolateral edge. RTA large trianguloid, widest basally, laterally resembles lip of univalve mollusc with strong sclerotised ridged fold dorsally meeting rounded fold with less sclerotisation and basal twisting ridge ventrally. From above, dorsal process pointed, horn-like, ventral lobe rounded with subapical lobe, intervening area unsclerotised. Cymbium dorsally with long white hairs and brown bristles, none thick, scopula absent; apical cone short, sharply conical with pallid crescent under apex; lateral margins all narrow. Median apophysis large, like head of cobra with narrow prolateral edge, narrow ridge, and scooped retrolateral flare sclerotised for most of its length and fused on prolateral edge to base of embolus. Embolus originates probasally, sweeps above median apophysis, unsclerotised conductor extends from prolateral corner of tegulum to behind median apophysis. Tegulum deep, gourd-shaped. Subtegulum smaller L-shaped with narrow ridge between embolus base and basal tegulum.
