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.
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]
The Dysderoidea are a clade or superfamily of araneomorph spiders. The monophyly of the group, initially consisting of the four families Dysderidae, Oonopidae, Orsolobidae and Segestriidae, [2] has consistently been recovered in phylogenetic studies.
Heptathelidae is a family of spiders. [1] It has been sunk within the family Liphistiidae as the subfamily Heptathelinae, [2] but as of April 2024 was accepted by the World Spider Catalog. [1] It is placed in suborder Mesothelae, which contains the most basal living spiders.
Miturgidae is a family of araneomorph spiders that includes nearly 170 species in 29 genera worldwide. [1] First described by Eugène Simon in 1886, [2] it has been substantially revised, and includes the previous family Zoridae as a synonym, [3] and excludes the family Xenoctenidae. [4]
The family Pacullidae contains three-clawed spiders with six eyes, lacking a cribellum. They resemble spiders from the family Tetrablemmidae in some respects but are much larger, always exceeding 5 mm long, have a very wrinkled (rugose) cuticle, and females do not have large membranous receptacles.
Phrurolithidae is a family of araneomorph spiders, known as guardstone spiders. The family was first described by Nathan Banks in 1892. [ 1 ] First included in the Corinnidae as the subfamily Phrurolithinae, later phylogenetic studies justified a separate family.
Micrathena, known as spiny orbweavers, is a genus of orb-weaver spiders first described by Carl Jakob Sundevall in 1833. [5] [6] Micrathena contains more than a hundred species, most of them Neotropical woodland-dwelling species. The name is derived from the Greek "micro", meaning "small", and the goddess Athena. [7]
