Opisthopatus roseus is a species of velvet worm in the Peripatopsidae family. As traditionally defined, this species is rose pink with 18 pairs of legs. Known as the pink velvet worm, it is found only in the Weza Forest, a Mistbelt Forest in South Africa. Specimens have been found on the forest floor amongst leaf litter, beneath, and within fallen logs.
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. 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.
Peripatopsidae is one of the two living velvet worm families.
Eoperipatus is a Southeast Asian genus of velvet worm in the family Peripatidae. The number of legs in this genus varies within species as well as among species and ranges from 22 pairs to 25 pairs. This genus exhibits lecithotrophic ovoviviparity; that is, mothers in this genus retain yolky eggs in their uteri.
Eoperipatus horsti is a species of velvet worm in the Peripatidae family. This species is brown with pale spots and a darker line running down the middle of its back. Females of this species have 24 or 25 pairs of legs; males have 23 or 24, usually 23. The males of this species can reach 40 mm in length, and the females can reach 46 mm in length, but the average specimen is 34 mm in length. The type locality is in West Malaysia.

Opisthopatus cinctipes is a species of velvet worm in the Peripatopsidae family. This species has 16 pairs of legs, all with claws and all used for walking. The color of the dorsal surface varies from blue to olive green. Females range from 7 mm to 50 mm in length, whereas males range from 6 mm to 36 mm. Like other velvet worms in this genus, this species exhibits matrotrophic viviparity, that is, mothers in this genus retain eggs in their uteri and supply nourishment to their embryos, but without any placenta. The type locality is in South Africa.
Opisthopatus amatolensis is a species of velvet worm in the Peripatopsidae family. This species has 16 pairs of legs. The type locality is in South Africa. The validity of this species is uncertain: Although some authorities deem O. amatolensis to be invalid even as a subspecies of O. cinctipes, a similar species also found in South Africa, other authorities recognize O. amatolensis as a separate species, citing the significant distance between the type localities of these two species.
Opisthopatus amaxhosa is a species of velvet worm in the family Peripatopsidae. This species is a clade in the O. cinctipes species complex. This species has 16 or 17 pairs of legs in both sexes and varies from light to dark pink on the dorsal surface and from dark to light brown on the ventral surface. Males of this species range from 12 mm to 14 mm in length. Also known as the Xhosa velvet worm, this species is found in the Eastern Cape province in South Africa.
Opisthopatus drakensbergi is a species of velvet worms in the family Peripatopsidae. This species is a clade in the O. cinctipes species complex. This species has 16 pairs of legs. Specimens are brown and slate black with a line down the middle of the back and a brown ventral surface. The original description of this species is based on a male holotype measuring 13 mm in length. This species is found at high altitude in the forests of the Drakensberg mountains in KwaZulu-Natal province in South Africa.
Opisthopatus highveldi is a species of velvet worm in the family Peripatopsidae. This species is a clade in the O. cinctipes species complex. This species has 16 pairs of legs and varies in color from brown to black to indigo. The original description of this species is based on two holotypes ranging from 16 mm to 17 mm in length. Also known as the Highveld velvet worm, this species is found in indigenous forest patches along the Highveld in Mpumalanga province in South Africa.
Opisthopatus kwazululandi is a species of velvet worm in the family Peripatopsidae. This species is part of the O. cinctipes species complex. This species has 16 pairs of legs. The color of its dorsal surface varies from brown to rose pink, and the ventral surface ranges from light brown to creamy white. The original description of this species is based on a male holotype measuring 16 mm in length and a female holotype measuring 22 mm in length. Also known as the coastal velvet worm, this species is found in Eastern Cape province and Kwazulu-Natal province in South Africa.
Opisthopatus laevis is a species of velvet worm in the Peripatopsidae family. This species has 16 pairs of legs. The type locality is in South Africa. The validity of this species is uncertain: Some authorities consider O. laevis invalid even as a subspecies of O. cinctipes, a similar species also found in South Africa, but other authorities recognize O. laevis as a separate species, citing the significant distance between the type localities of these two species.
Oroperipatus lankesteri is a species of velvet worm in the Peripatidae family. This species is brownish grey and is notable for its large size, which ranges from 32 mm up to 82 mm in length. Females of this species have 37 or 38 pairs of legs; males have 33 to 35 pairs. Like other neotropical peripatid velvet worms, this species is viviparous, with mothers supplying nourishment to their embryos through a placenta. The type locality is in Ecuador.
Peripatus dominicae is a species of velvet worm in the Peripatidae family. Males of this species have 25 pairs of legs; females can have 28 to 31 pairs of legs, but usually have 29. Females in this species range in size from 29 mm to 56 mm in length, while males range from 17 mm to 25 mm in length. The original description of preserved specimens report that this species is usually reddish brown with a diffuse darker streak down the middle of the back, with a much paler "light grey or greyish yellow" ventral surface. Like other neotropical peripatid velvet worms, this species is viviparous, with mothers supplying nourishment to their embryos through a placenta. The type locality is in Dominica.
Peripatopsis intermedia is a species of velvet worm in the Peripatopsidae family. This species is about 33 mm long and has 19 pairs of legs: 18 pregenital leg pairs plus a last pair of much reduced legs. The type locality is in South Africa. Although some authorities doubt the validity of this species and deem it to be a junior synonym of P. balfouri, others consider these two to be separate species, citing the distance between their type localities.
Peripatopsis moseleyi is a species of velvet worm in the Peripatopsidae family. Males of this species have 20 to 24 pairs of legs with claws ; females have 19 to 23 pairs of legs with claws. Females range from 11 mm to 75 mm in length, whereas males range from 9 mm to 50 mm. The type locality is in South Africa.
Macroperipatus ohausi is a species of velvet worm in the Peripatidae family. Females of this species have 27 or 28 pairs of legs. The type locality is Rio de Janeiro, Brazil.
Opisthopatus herbertorum is a species of velvet worm in the Peripatopsidae family. The type locality is in South Africa. As originally described, this species is uniformly white with 17 pairs of legs. Subsequent phylogenetic results, however, cast doubt on this species delimitation based on morphology, indicating instead that O. herbertorum is a junior synonym of O. roseus.
Ooperipatellus spenceri is a species of velvet worm in the family Peripatopsidae. This species has 14 pairs of legs. Although found in Tasmania, Australia, these velvet worms were first assigned to O. insignis, a similar species found in Victoria, Australia, before being named as a separate species. Authorities recognize O. spenceri as a different species, noting the significant distance between the type localities of these two species and their separation by the Bass Strait.
