The family Dipluridae, known as curtain-web spiders (or confusingly as funnel-web tarantulas, a name shared with other distantly related families [2]) 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.
Mated males are castrated in the process of mate plugging, though this may be an advantage in mate guarding, as mated males have been observed to fight more aggressively and win more frequently than virgin males. [4] So while the female spiders are still at least potentially polygamous, the males have become monogamous.
Nemesiidae is a family of mygalomorph [1] spiders first described by Eugène Simon in 1889, [2] and raised to family status in 1985. Before becoming its own family, it was considered part of "Dipluridae". [3] The family is sometimes referred to as wishbone spiders due to the shape of their burrows. [4]
Palpimanidae, also known as palp-footed spiders, is a family of araneomorph spiders first described by Tamerlan Thorell in 1890. [1] They are widely distributed throughout the tropical and subtropical regions of the world, the Mediterranean and one in Uzbekistan, but not Australia. They are not common and there is a high degree of endemism. [2]
