Chasing ghosts: The phylogeny of Amaurobioidinae ghost spiders (Araneae, Anyphaenidae)

The family Anyphaenidae, also known as ghost spiders, includes a diverse array of nocturnal cursorial spiders that actively hunt on vegetation. The family is mostly distributed in the Americas and has been traditionally divided into three subfamilies. The mostly tropical and North American Anyphaeni...
