Psilodercidae
Psilodercidae is a family of spiders first described as a subfamily of Ochyroceratidae by Machado in 1951 and raised to family rank by J. Wunderlich in 2008. These spiders can be distinguished by the "segestriid positioning" of their six eyes, the absence of leg bristles, strong bristles on the cymbium, and several pairs of spermathecae in females. Genera. , the World Spider Catalog accepts the following genera, but it is relatively unstudied and may change as more information becomes available. In particular, Wunderlick remarked that "Psiloderces" is too broad and should be split into smaller, more distinct groups.
