Menemerus bivittatus (Dufour, 1831) Cosmopolitan Jumping Spider

Note: some Menemerus bracteatus also on this page.

This is a cosmopolitan jumping spider associated with humans in the warmer parts of the world, found in houses and on walls in cities. In Australia it has been reported in coastal Queensland. Both the female and the male have white fringing sides of the cephalothorax, rather like a scarf or sash, giving rise to the species name which means wearing a decorative ribbon. The female has a mostly light coloured upper surface of the abdomen, the male has a central narrow dark V shape. The male palp is a rather uncomplicated affair, having a simple upward pointing embolus with a membranous conductor. The female has very large and fluffy palps. ♀ 10mm ♂ 9mm
