Diagnosis. The male of this species has a unique form of the tibial apophysis: broad, bent outwards, and shovelshaped ( Fig. 69 ). The female has an epigyne with a very wide and deep posterior pocket ( Fig. 72 ).

Etymology. The species is dedicated to Wayne P. Maddison, the creator of the new salticid phylogenetic systematics.

Description. Male. Measurements. Cephalothorax: length 2.4–2.9, width 1.7–2.1, height 1.3–1.5. Eye field: length 1.2–1.4, anterior width 1.7–2.0, posterior width 1.5–1.8. Abdomen: length 2.3–2.9, width 1.2–1.5. General appearance as in Fig. 61 . Carapace very high, abruptly sloping posteriorly, dark brown, with slightly lighter foveal area. Anterior median eyes encircled by white and reddish-orange hairs, other eyes surrounded by black rings. Some colourless bristles and hairs on carapace. Mouthparts brown. Chelicerae stout, with two separate teeth on both margins and long fang with two short apophyses ( Figs 63 , 67 ). Sternum light brown. Abdomen narrow, yellowishgrey, lighter medially, with slightly darker patches at margins. Venter grey. Spinnerets long, yellow. Legs long, first pair yellow, with brown femora and tarsi, tips of tibiae and metatarsi also darker. Tibia I with four pairs of long ventral spines and 1-1 on prolateral side, metatarsus with three ventral pairs and 2 spines on both lateral surfaces. Patella I with single prolateral spine ( Fig. 64 ). Other legs yellow. Pedipalps brownish, hairy, tibia long, with big retrolateral extension ( Figs 68, 71 ). Tibial apophysis very wide, with straight truncated tip bent outwards (shovelshaped) ( Figs 66 , 69, 70 ).

Female. Measurements. Cephalothorax: length 2.1–2.2, width 1.6–1.7, height 1.1–1.3. Eye field: length 1.1– 1.3, anterior width 1.6–1.7, posterior width 1.4–1.5.Abdomen: length 2.4-2.5, width 1.6–1.7. General appearance as in Fig. 62 . Smaller than male, lighter coloured. Carapace light yellowish, eye field fawn, eyes with dark rings. White hairs encircle anterior median eyes and form small spots in front of eyes of last row. Few light hairs on eye field. Mouthparts yellowish. Abdomen yellow, with few pairs of blackish markings ( Fig. 62 ), venter light. Legs yellow. Spination of first leg as in male, spines brown, ventral spines very long. Palpal tarsus with single retrolateral spine. Epigyne with wide depression and big deep pockets at its posterior edge ( Figs 72, 73 ). Internal structure as in Figs 74, 75 , copulatory openings placed laterally at posterior edge of epigynal depression, seminal ducts very wide in inlet part, but narrowed and looping at spermathecae.

Distribution. Known from Gabon only.
