Helsdingenia is a genus of dwarf spiders that was first described by Michael I. Saaristo & A. V. Tanasevitch in 2003.[2] The name is a reference to Dr. P. J van Helsdingen.[3]
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.
