Epiperipatus imthurni is a species of velvet worm in the family Peripatidae. This species ranges from light orange or yellowish brown to a dark brown on its dorsal surface; the ventral surface is a lighter orangeish shade of the same color. The type locality is in Guyana. No males have been recorded from this species. Females can reach a large size, up to 2.25 g in weight, and range from 25 mm up to 96 mm in length. They have 29 to 32 pairs of legs, usually 30 or 31.

Epiperipatus barbadensis is a species of velvet worm in the Peripatidae family, first described based on specimens from Barbados. It is one of the velvet worms that most often is kept in captivity, and was the first member of the Peripatidae family to be successfully maintained by hobbyist invertebrate keepers; it is easier to keep than the majority of other velvet worm species that have been tried, but still has specialized requirements that resemble those necessary for keeping poison dart frogs. E. barbadensis is social, nocturnal and viviparous, can live for several years, and feeds on small invertebrates that are caught by ejecting an adhesive slime from glands on their head.

Epiperipatus acacioi is a species of velvet worm in the Peripatidae family. This species is dark purple with a bilaterally symmetric pattern on its dorsal surface and ranges from 13 mm to 47 mm in length.

Epiperipatus vagans from Barro Colorado Island (Panama) was originally described as subspecies of Epiperipatus brasiliensis, but is now treated as a full species.
