[3] The validity of this species is uncertain: [4] Some authorities consider O. laevis invalid even as a subspecies of O. cinctipes , a similar species also found in South Africa, [2] [5] but other authorities recognize O. laevis as a separate species, citing the significant distance (570 km) between the type localities of these two species.

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.

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.

<i>Peripatopsis</i> Genus of velvet worms

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. 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.

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.

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.

<i>Opisthopatus kwazululandi</i> Species of velvet worm

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 natalensis 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 have deemed O. natalensis to be a subspecies of O. cinctipes, a similar species also found in South Africa, and others regard O. natalensis as invalid even as a subspecies, still other authorities recognize O. natalensis as a separate species, citing the significant distance between the type localities of these two species.

Cephalofovea tomahmontis is a species of velvet worm in the Peripatopsidae family. This species is ovoviviparous, has 15 pairs of oncopods (legs), and lives in rotting logs and leaf litter. The type locality is Mount Tomah, New South Wales, Australia, after which this species is named. Like all members of the genus Cephalofovea, both sexes of C. tomahmontis have a furrow on the head, between the antennae, which the male everts to carry his spermatophore to the female.

Paraperipatus lorentzi is a species of velvet worm in the Peripatopsidae family. This species is a dark green-blue. Females of this species have 22 to 28 pairs of legs; males have 21 or 22 pairs of legs. Whereas the original description of this species records 19 mm as the length of a male specimen, females range from 33 mm to 60 mm in length. The type locality is in Western New Guinea, Indonesia. The validity of this species is uncertain: Although some authorities deem P. lorentzi to be a junior synonym of P. papuensis, a similar species also found in Western New Guinea, others recognize them as two separate species.

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.

<i>Peripatopsis moseleyi</i> Species of velvet worm

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.

Peripatopsis sedgwicki is a species of velvet worm in the Peripatopsidae family. Also known as the Tsitsikamma velvet worm, this species varies from blue-tan green to bright orange and brown violet. This velvet worm has either 19 or 20 pairs of legs in most populations, but a discrete population in the Fort Fordyce Nature Reserve has either 22 or 23 leg pairs and probably represents a novel species. The last leg pair in this species features a claw and is reduced more in the male than in the female. Females of this species range in size from 12 mm to 68 mm in length, whereas males range from 10 mm to 46 mm in length. 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. This species has a limited geographic distribution but is especially abundant in the indigenous forest of the Tsitsikamma mountains.

<i>Peripatopsis alba</i> Species of velvet worm

Peripatopsis alba, the white cave velvet worm, is a species of velvet worm in the family Peripatopsidae. This species has 18 pairs of clawed legs, with the last pair reduced, and no eyes. Specimens range from 32 mm to 48 mm in length. 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.

Peripatopsis leonina, the Lion's Hill velvet worm, is a species of velvet worm in the Peripatopsidae family. This species has 20 to 24 pairs of legs, usually 21 or 22 leg pairs, with the last pair of legs reduced. Females of this species range from 7 mm to 41 mm in length, whereas males range from 7 mm to 34 mm.

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.
