Cephalothorax length 5.00 mm, width 4.20 mm. Abdomen length 4.90 mm, width 3.65 mm. <i>Carapace.</i> Brown except yellow brown cephalic posterior of the eye area. Fovea distinctly long and deep, about one-third thoracic width. Chelicerae yellowish gray, 2.5 x longer than wide, base with three humps including the lateral condyle. Promargin with three and retromargin with four teeth. Subbasal tooth of retromargin the largest. Pedipalp brown with dark brown palpal organ and paracymbium. Maxillae and labium yellow brown with retrolateral of maxillae and apical margin of labium yellow. Sternum yellow with a white median longitudinal band, posterior end acutely pointed and sclerotized lateral extensions present between coxae II and III reaching ventrolateral side of carapace. <i>Eyes.</i> In two rows. AER slightly longer than PER, both strongly recurved. Eye diameter (mm): AME (0.21)&gt; ALE=PME (0.17)&gt; PLE (0.14). Eye separation (mm): PME-PLE (0.54)&gt; AME-ALE (0.34)&gt; AME-AME (0.26)&gt; PME-PME (0.14). Clypeus height narrow barely 0.66 AME diameter. <i>Legs.</i> Relatively spinous, brown with a pair of subspherical yellow spots in the retrolateral of femur I, elongate longitudinal and transversely elongate yellow bands present in femur II, yellow posterior half of femur III and subbasal yellow band in tibia III and IV. Metatarsi III and IV with a subbasal and median yellow band. Spination in femur I 4 - 3 - 3-5 and femur II 6-10 - 5 - 5. Tibia II with 56 prolateral spines mostly short to peg-like. Leg formula 1-4 - 2-3. <i>Abdomen.</i> Blackish brown, ovate with long yellow hairs dorsally, midanterior with a black dagger-like band.

This species is very similar in facies to <i>Neoscona vigilans</i> (Blackwall, 1865) but differs from the latter in the following characters, namely, (1) number of prolateral spines in tibia II, (2) leg II and IV subequal in length, (3) shape of median apophysis, (4) tip of tegular apophysis, (5) number of long spines in the patella of pedipalp, and (6) structure of pedipalp’s tibia. <i>Etymology.</i> The from the type locality. specific epithet is derived
