Peripatus is a genus of velvet worms in the Peripatidae family. The name "peripatus" is also used to refer to the Onychophora as a whole, although this group comprises many other genera besides Peripatus. The genus Peripatus is found in Central America, the Caribbean and northern South America. Velvet worms in this genus may have as few as 24 or 25 pairs of legs or as many as 36 leg pairs. This genus is viviparous, with mothers supplying nourishment to their embryos through a placenta.
Macroperipatus is a genus of Neotropical velvet worms in the Peripatidae family. Velvet worms in this genus can have as few as 24 pairs of legs or as many as 42 leg pairs. This genus is viviparous, with mothers supplying nourishment to their embryos through a placenta.
Opisthopatus is a genus of South African velvet worms in the family Peripatopsidae. The number of legs in this genus range from 16 pairs to 18 pairs. The feet in this genus feature three distal leg papillae: one anterior, one posterior, and one median. Mothers in this genus give birth to live young. In particular, this genus exhibits matrotrophic viviparity, that is, mothers in this genus retain eggs in their uteri and supply nourishment to their embryos, but without any placenta.
Peripatopsis is a genus of South African velvet worms in the Peripatopsidae family. The number of legs in this genus ranges from as few as 16 pairs to as many as 25 pairs and varies within species when the number is greater than 18 pairs. Velvet worms in this genus feature a last pair of legs that is rudimentary or reduced in size, mainly in males. The feet in this genus feature three distal leg papillae: two anterior and one posterior.
Peripatidae is a family of velvet worms. The oldest putative representatives of the family herald from Burmese amber dated to the mid-Cretaceous, around 100 million years ago, with representatives from Dominican and Baltic amber attesting to a broader distribution in the Palaeogene / Neogene; molecular variability suggests that the family's crown group may have arisen in the early Mesozoic.
Peripatopsidae is one of the two living velvet worm families.

The type locality is in central Chile. Velvet worms in this genus have 16 pairs of legs. This genus exhibits matrotrophic viviparity, that is, mothers in this genus retain eggs in their uteri and supply nourishment to their embryos, but without any placenta.
Paraperipatus is a genus of velvet worms in the family Peripatopsidae. The number of legs vary within species as well as among species in this genus and can range from as few as 21 pairs up to 27 pairs in males and 29 pairs in females. The maximum number of leg pairs recorded in this genus (29) is also the maximum number of leg pairs found in the family Peripatopsidae. This genus exhibits matrotrophic viviparity, that is, mothers in this genus retain eggs in their uteri and supply nourishment to their embryos, but without any placenta. Species in this genus are found in New Guinea and Maluku, Indonesia.
