Cyphophthalmi is a suborder of harvestmen, with about 36 genera, and more than hundred described species. The six families are currently grouped into two infraorders, the Tropicophthalmi and the Temperophthalmi; however, these are not supported by modern phylogenetic analysis.
They are smaller than the more familiar "daddy long-legs" harvestmen, with adults ranging from 1 to 6mm, including legs. Moreover, their legs are comparatively short compared to their body length, typically shorter than the body. Some superficially resemble mites. Their coloration is almost always some shade of brown, with a heavily sclerotized body, and they are quite inconspicuous, residing in leaf litter or in caves. Many cyphophthalmids are eyeless, and presumably rely on olfactory cues to find food and mates. Their scent glands are located on special elevated cones called ozophores. They have low dispersal rates and consequently high endemism.
