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 across. Isoxya have a sclerotised (or porcelain-like) abdomen which is typical of the Gasteracanthinae.
Description
These spiders have a carapace that is usually as wide as it is long. Their abdomen is brightly decorated with yellow, red or black and white patterns. The dorsal part is hardened to form a rigid scutum bearing large spots and depressions, often prolonged laterally and posteriorly in spine-like extensions.
The spinnerets are surrounded by a sclerotised ring. Legs are relatively short. The eight eyes are in two rows (4:4). Males are much smaller than females and differ in color and shape.
Lifestyle
During the day box kite spiders can be found in large orb-webs usually made high between trees. The web is usually decorated with small silk tufts. The egg sacs are covered with silk and they attach it to vegetation.
