dipluridae
The family Dipluridae, known as funnel-web tarantulas, are a group of spiders in the infraorder Mygalomorphae, that have two pairs of booklungs, and chelicerae (fangs) that move up and down in a stabbing motion. A number of genera, including that of the Sydney funnel-web spider (''Atrax''), used to be classified in this family but have now been moved to Hexathelidae.
==Description==
Dipluridae lack a rastellum (stout conical spines) on their chelicerae. Their carapace is characterized by the head region not being higher than the thoracic region. Their posterior median spinnerets (silk-extruding organs) are much shorter than their posterior lateral spinnerets, which have three segments, and are elongated (almost as long as their opisthosoma). Most of the species are medium to small-sized spiders, with some, such as the endangered ''Microhexura montivaga'', as small as 3 mm, while others may measure about 15 mm.〔Murphy & Murphy 2000〕 The cave species ''Masteria caeca'' is eyeless.
