FEMALE. Holotype female, total length 1.24mm. Cephalothorax length 0.57mm, width 0.45mm. Abdomen length 0.67mm, width 0.58mm.
Carapace. Yellow with a thin lyre-shape grayish brown marking in the cephalic and inverted Y -marking in the thoracic area, 1.26x longer than wide. Lateral margins brown. Chelicerae yellow, 2x longer than wide (0.20mm: 0.10mm). Pedipalp, labium and maxillae yellow. Apical margins of maxillae not converging and narrower than base. Labium broad apically, constricted basally and connected to sternum. Sternum as long as wide, yellow with gray brown mottles.
Eyes. Six eyes arranged in three pairs of two, median pair distinctly more robust than the lateral pairs (0.11mm: 0.09mm). First row of four eyes slightly procurved. Second row straight and widely separated. Eye diameter (mm): AME (0.06)> PLE (0.05)> ALE (0.04). PLE-PLE separation 2.7x AME diameter. Clypeus height slightly more than 1 AME diameter.
Legs. Uniformly yellow. Venter of tibia IV with an apical spine and a dorsal bristle subposteriorly. Femur IV medially swollen with an apicolateral spine, inner area depressed and subdorsal border lined with short hairs. Pedipalp slightly longer than femur II and as long as femur IV. Leg formula 4213.

Diagnostic Features. This species is similar to S. pongo Deeleman-Reinhold but differs from the latter in the (1) pigmentation design in the cephalothorax, (2) color of sternum, (3) tibia IV with only two spines, (4) femur II as long as femur IV, and (5) longer pedipalps.
Etymology. Patronym, in honor of Dr. Robert R. Jackson for his untiring interest and pioneering works on the behaviour of jumping spiders.
