The coneweb spiders of the family Diguetidae are six-eyed haplogyne (lacking hardened female genitalia, or epigyne) spiders that live in tangled space webs. They fashion a cone-like central retreat in which they hide and lay eggs. The family is small (three genera and only 15 species) and is confined to the New World, where it is usually found in deserts. Members of the genus Diguetia usually build their webs in shrubs or between cactus pads. Although they have the same eye arrangement as the venomousrecluse spiders (family Sicariidae) , none of these genera are known to be harmful to humans. The epigyne or epigynum is the female genital opening in spiders. ...

They can be observed swaying from side to side, in order to cover the prey in a crisscrossed "Z" pattern; each of two pores in the chelicerae emits half of the pattern.
Like the Sicariidae and Diguetidae these spiders are haplogyne (lack hardened female genitalia) and have six eyes, which are arranged as three pairs.
They differ from these in having a dome-shaped carapace and in their characteristic flecked pattern of spots, which to Westerners often resembles Arabic or Chinese writing.
