Oroperipatus is a genus of Neotropical velvet worms in the family Peripatidae. [1] [2] Species in this genus are found in South America west of the Andes and in Mexico. [3] This genus is viviparous, with mothers supplying nourishment to their embryos through a placenta. [4]
Velvet worms in this genus can have as few as 22 pairs of legs (in O. omeyrus ) or as many as 40 leg pairs (in O. bluntschli , O. weyrauchi , and O. tiputini ). [5] [6] Species in this genus have from four to seven distal foot papillae, with two or more on the anterior part of the foot and two or more on the posterior part of the foot. [7] This genus also features a nephridial tubercle on the fourth and fifth leg pairs inserted into a complete third spinous pad. [6]
The genus contains the following species:
Oroperipatus goudoti(Bouvier, 1899), Oroperipatus quitensis(Schmarda, 1871), and Oroperipatus peruanus(Grube, 1876) are considered nomina dubia by Oliveira et al. 2012.
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. 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.
Plicatoperipatus is a monospecific genus of velvet worm containing the single species Plicatoperipatus jamaicensis. It is endemic to Jamaica. Females of this species can have as many as 43 pairs of legs, the maximum number found in the phylum Onychophora. In a large sample collected in 1988, however, females ranged from 35 to 39 leg pairs, with 37 as the mean and the most common number, and males ranged from 31 to 37 leg pairs, with 35 as the mean and the most common number. This species ranges from 25 mm to 65 mm in length. In the 1988 sample, the mean length for males was 33 mm, and the mean length for mature females was 51 mm. This species is viviparous, with mothers supplying nourishment to their embryos through a placenta.
Typhloperipatus is a genus of velvet worm in the family Peripatidae, containing the sole species Typhloperipatus williamsoni. This genus is notable for containing the only species in the phylum Onychophora found in South Asia. This species is also striking in that this velvet worm shows no external trace of eyes, although rudimentary optical vesicles are present internally.
Peripatidae is a family of velvet worms. This family includes more than 90 described species distributed among 13 genera, but some authorities deem only 80 of these species to be valid. 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. This family includes more than 140 described species distributed among 41 genera, but some authorities deem only 131 of these species to be valid. The French zoologist Eugène Louis Bouvier proposed this family in 1905 with Peripatopsis as the type genus.
Eoperipatus is a genus of velvet worms in the family Peripatidae. These velvet worms have been reported from locations throughout Southeast Asia, including Malaysia, Singapore, Thailand, and Vietnam. This genus exhibits lecithotrophic ovoviviparity; that is, mothers in this genus retain yolky eggs in their uteri.
Epiperipatus is the most diverse genus of neotropical velvet worms in the family Peripatidae. Species in this genus are found in Central and South America. Velvet worms in this genus can have as few as 23 pairs of legs or as many as 39 leg pairs. This genus is viviparous, with mothers supplying nourishment to their embryos through a placenta.
Heteroperipatus is a genus of Central American velvet worms in the Peripatidae family. The number of legs in this genus varies within species as well as among species and ranges from 26 pairs to 32 pairs. This genus is viviparous, with mothers supplying nourishment to their embryos through a placenta.
Cerradopatus is a monospecific genus of velvet worm containing the single species Cerradopatus sucuriuensis. Males of this species have 28 or 29 pairs of legs; females have 30 to 32. This species is native to the Brazilian savannah. This species is viviparous, with mothers supplying nourishment to their embryos through a placenta.
Paropisthopatus is a monospecific genus of velvet worm containing the single species Paropisthopatus umbrinus. Females of this species range from 20 mm to 70 mm in length. 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.
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. Males of this species have 24 to 27 pairs of legs, usually 25 or 26; females have 26 to 30, usually 27 or 28. The type locality is in Minas Gerais, Brazil.
Oroperipatus bimbergi is a species of velvet worm in the Peripatidae family. The female of this species has 27 or 28 pairs of legs, usually 27; the male has 24 or 25 usually, rarely 26. The type locality is in Colombia.
Oroperipatus bluntschli is a species of velvet worm in the Peripatidae family. The original description of this species is based on a female specimen measuring 100 mm in length; its 40 pairs of legs are notable for approaching the maximum number (43) recorded in velvet worms. The type locality is in Peru.
Oroperipatus corradoi is a species of velvet worm in the Peripatidae family. Females of this species have 26 to 29 pairs of legs, usually 28; males have 24 to 27. Females range from 14 mm to 60 mm in length, while males range from 14 mm to 25 mm in length. The type locality is in Ecuador.
Oroperipatus eisenii is a species of velvet worm in the family Peripatidae. Females of this species have 27 to 29 pairs of legs, usually 28; males have 23 to 26. Females range from 30 mm to 57 mm in length, while males range from 20 mm to 23 mm. The type locality is found in Brazil and central Mexico.
Oroperipatus lankesteri is a species of velvet worm in the Peripatidae family. This velvet worm is notable for its large size, reaching 82 mm in length. This species is known only from its type locality in the northern Pacific lowlands of Ecuador.
Oroperipatus omeyrus is a species of velvet worm in the Peripatidae family. This species is blackish red on its dorsal surface but lighter and brownish on its ventral surface. The original description of this species is based on female specimens with 24 to 26 pairs of legs and an embryo with 22 pairs of legs. The females range from 16 mm to 22 mm in length. The type locality is in Peru.
Oroperipatus weyrauchi is a species of velvet worm in the Peripatidae family. The original description of this species is based on only two specimens, a male with 40 pairs of legs and a larger female with 38 leg pairs. The type locality is in Peru.
Mongeperipatus is a genus of velvet worms in the family Peripatidae from Costa Rica. The biologists José Pablo Barquero-González, Steven Sánchez-Vargas, and Bernal Morera-Brenes introduced this genus in 2020 to contain the newly discovered type species, M. kekoldi, together with another species, M. solorzanoi. A phylogenetic analysis using DNA sequences placed these two species in their own monophyletic clade. Furthermore, these two species share morphological characters that indicate that these species do not belong in the other genera and instead belong together in a separate genus. The genus Mongeperipatus is named in honor of the Costa Rican biologist Julián Monge-Nájera.
