Peripatopsis
''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 (e.g., in '' P. clavigera'') to as many as 25 pairs (in '' P. moseleyi'') and varies within species when the number is greater than 18 pairs. Velvet worms in this genus feature a last pair of legs (the genital pair) 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. Species The genus ''Peripatopsis'' consists of the following species: * '' Peripatopsis alba'' Lawrence, 1931 — white cave velvet worm * '' Peripatopsis balfouri'' (Sedgwick, 1885) * '' Peripatopsis birgeri'' Ruhberg & Daniels, 2013 * '' Peripatopsis bolandi'' Daniels et al., 2013 * '' Peripatopsis capensis'' (Grube, 1866) * '' Peripatopsis cederbergiensis'' Daniels et al., 2013 * '' Peripa ...

Peripatopsis Moseleyi
''Peripatopsis moseleyi'' is a species of velvet worm in the Peripatopsidae family. Males of this species (as traditionally defined) have 20 to 24 pairs of legs with claws (plus one pair without claws); females have 19 to 23 pairs of legs with claws (plus one pair without 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. More recent phylogenetic results indicate that this species as traditionally defined is instead a species complex In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each oth ... (''P. moseleyi sensu lato'') containing five genetically distinct clades, now described as separate species: '' P. birgeri'', '' P. hamerae'', '' P. janni'', '' P. stortchi'', and ''P. moseleyi sensu st ...

Peripatopsis Sedgwicki
''Peripatopsis sedgwicki'' is a species of velvet worm in the Peripatopsidae family. Also known as the Tsitsikamma velvet worm, this species has a narrow geographic distribution in South Africa but is especially abundant in the indigenous forest of the Tsitsikamma mountains. Recent phylogenetic analysis suggests that ''Peripatopsis sedgwicki'' is a species complex that contains three clades, each with a distinct geographic distribution, including at least one clade that may represent a novel species. Discovery This species was first described under the name ''Peripatus dewaali'' by the Dutch zoologist Max Weber in 1898 based on specimens he collected near the town on Knysna in the Western Cape province of South Africa. In 1899, the South African zoologist William F. Purcell provided a more detailed description of this species based on a male and eleven females that he found in 1896 in rotten wood in the forest and under heaps of weeds on farms near the town of Knysna. He named ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Onychophoran Genera
Onychophora (from grc, ονυχής, , "claws"; and , , "to carry"), commonly known as velvet worms (due to their velvety texture and somewhat wormlike appearance) or more ambiguously as peripatus (after the first described genus, ''Peripatus''), is a phylum of elongate, soft-bodied, many-legged panarthropods. In appearance they have variously been compared to worms with legs, caterpillars, and slugs. They prey upon other invertebrates, which they catch by ejecting an adhesive slime. Approximately 200 species of velvet worms have been described, although the true number of species is likely greater. The two extant families of velvet worms are Peripatidae and Peripatopsidae. They show a peculiar distribution, with the peripatids being predominantly equatorial and tropical, while the peripatopsids are all found south of the equator. It is the only phylum within Animalia that is wholly endemic to terrestrial environments, at least among extant members. Velvet worms are generally ...
