This species, the only one of its genus, is one of the small money spiders and is around 2.3 mm in length. It occurs throughout the United Kingdom, but is not particularly common. The pits on the carapace, in both sexes, are characteristic of the species. The carapace of the male is raised at the front, more so than that of the female and has an ocular sulcus (groove), as can be seen in the micrographs.
