Polyxenus is a genus of millipede in the order Polyxenida, containing at least 30 valid species as of 2012. [1]
Dendryphantes is a genus of jumping spiders that was first described by Carl Ludwig Koch in 1837.
Uloborus is a spider genus in the family Uloboridae with 80 described species. Most species occur in the tropics and subtropics, with only few species in northern America and Europe.
Lycosa is a genus of wolf spiders distributed throughout most of the world. Sometimes called the "true tarantula", though not closely related to the spiders most commonly called tarantulas today, Lycosa spp. can be distinguished from common wolf spiders by their relatively large size. This genus includes the European Lycosa tarantula, which was once associated with tarantism, a dubious affliction whose symptoms included shaking, cold sweats, and a high fever, asserted to be curable only by the traditional tarantella dance. No scientific substantiation of that myth is known; the venom of Lycosa spiders is generally not harmful.
Hogna is a genus of wolf spiders with more than 200 described species. It is found on all continents except Antarctica.
Dicranopalpus is a genus of harvestmen with twelve known recent species. Three fossil species have been described, all from Baltic amber, but only D. ramiger is currently considered valid.
Porcellio is a genus of woodlice in the family Porcellionidae. These crustaceans are found essentially worldwide. A well-known species is the common rough woodlouse, Porcellio scaber.
The Nemastomatidae are a family of harvestmen with about 170 described species in 16 recent genera. Several fossil species and genera are known.
The Pseudogarypidae are a small family of pseudoscorpions. Most recent species are found in North America, while one species is endemic to Tasmania.
Polyxenidae is a family of millipedes in the order Polyxenida containing approximately 47 species in 19 genera. Adults in all species in this family have 13 pairs of legs.
Phryssonotus is a genus of bristle millipedes containing around nine extant species. Species are characterized by the possession of dark, rear-projecting scale-shaped bristles (trichomes) on the tergites; all other bristles are long and hairlike. Adults in this genus have 17 pairs of legs, except for the species Phryssonotus brevicapensis, in which they have only 15 pairs of legs.
Lophoturus is a genus of millipedes belonging to the family Lophoproctidae. Species described after year 2000 include two from Queensland, Australia, three from Christmas Island, Australia, and three from the Caribbean and northern South America.
Nemastomatinae is a subfamily of harvestmen with over 125 described species in 19 (extant) genera. They are usually found in temperate regions.
Otostigminae is a large subfamily of centipedes, containing nearly half of all species in the family Scolopendridae. Members of this subfamily are abundant and widespread throughout the tropical and subtropical regions of the world, mostly in Africa, Asia, and Australia.
