They are usually pale colored spiders that grow up to 2.45 millimetres (0.096 in) long. Males are smaller than females, but females are distinguishable by their finger-like extensions in epigyne.[3] There are four pairs of dark spots in an abdominal pattern that are connected to each other, creating two parallel stripes.
