Regal Jumping Spider ( Male )

Description

Adult males of P. regius average 12 mm in length (range 6 to 18 mm). Males are always black with alternating black and white fringes on the first pair of legs; on the dorsum of the abdomen are a white basal band, a central triangular white spot, and a pair of oval white spots posteriorly. The paired chelicerae are enlarged and iridescent (green-blue-violet); each has a subdistal tubercle on its anterior face. The first legs of larger males are disproportionately longer than smaller males, a type of allometry.
