Box kite spider

Box kite spiders (Isoxya) is a genus of Afrotropical orb-weaver spiders first described by Eugène Simon in 1885. Like the spiny orb-weavers they have six prominent (but short) spines on their abdomen. They are small spiders, measuring 3 to 7 mm across. They have a sclerotised (or porcelain-like) abdomen which is typical of the Gasteracanthinae.
