Gasteracantha quadrispinosa, the four-spined jewel spider, is a brightly coloured species of spider in the spiny orb-weaver genus Gasteracantha.

[2] It occurs in wet forests of Queensland, Australia, and New Guinea,[1][3] where it builds vertical orb webs approximately 1.5 m across and hangs in the centre of the web to wait for prey.

[4] Female four-spined jewel spiders are distinctively shaped and coloured.

Their abdomens are flat, oblong, and curved slightly forward, 5-6 mm wide, excluding spines.

The hard, shiny upper surface of the abdomen ranges from red to yellow in colour and is marked with a black spot and dark sigilla.
