Diagnosis. The male of this species has a unique form of the tibial apophysis: broad, bent outwards, and shovelshaped ( Fig. 69 View FIGURES 67–71 ). The female has an epigyne with a very wide and deep posterior pocket ( Fig. 72 View FIGURES 72–75 ).

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