Styposis is a genus of comb-footed spiders that was first described by Eugène Louis Simon in 1894.[3] It is a senior synonym of Cyatholipulus.[2]

They are unpigmented, small spiders, usually measuring less than 2 millimetres (0.079 in) long. Comb-footed spiders usually have eight eyes, but most species have six large eyes, with the anterior median eyes extremely small or absent entirely. Members of Comaroma also have six eyes, but also have a large colulus and are less sclerotized.[4]
