see text The Stygnopsidae are a small family of harvestmen, with almost all species found in Mexico.
[1] The body length of these harvestmen ranges from 2.5 (Karos) to 7 mm (Hoplobunus).
Their color ranges from dark brown to black, with much lighter appendages.
Almost all species occur in Mexico, with some found in the southern USA (Hoplobunus), and Guatemala, El Salvador and Belize (Paramitraceras).
Although they reach into the Nearctic, they are more closely related to neotropical harvestmen.
