Oxyopes gracilipes is the only spider in the genus Oxypes in New Zealand.
Its a small jumping spider, with males having a body length of 4-5 mm and the females are larger with a body length up to 7mm. The cephalothorax (head and the thorax fused together) yellow-orange with three wide longitudinal brown to black stripes. The dorsal surface of the abdomen is orange with brown to black markings.

When the males are sexually mature, they ejaculate onto a sperm-web and suck up the sperm into their pedipalps. These inflate due to fluid pressure (as a state known as "being charged"). During mating, the males transfer sperm to the female from one of their pedipalps, which then will generally deflate.
