Epiperipatus is the most diverse genus of neotropical velvet worms in the family Peripatidae. [1] [2] [3] Species in this genus are found in Central and South America. [3] This genus is viviparous, with mothers supplying nourishment to their embryos through a placenta. [4]
Several traits are considered diagnostic for this genus. These traits include the number of scale ranks (four to eighteen) on the basal piece of the primary papillae, four complete spinous pads of the soles of the feet of the fourth and fifth pairs of legs, sometimes with vestiges of a fifth pad, a nephridial tubercle on the fourth and fifth leg pairs, located between the third and fourth spinous pads, and in males, one to three pairs of pregenital legs with crural papillae. Velvet worms in this genus can have as few as 23 leg pairs (in E. hyperbolicus ) or as many as 39 leg pairs (in E. titanicus ). [3]
The genus contains the following species:
Epiperipatus nicaraguensis(Bouvier, 1900) and Epiperipatus tucupi(Froehlich, 1968) 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.
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.
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.
Oroperipatus is a genus of Neotropical velvet worms in the family Peripatidae. Species in this genus are found in South America west of the Andes and in Mexico. This genus is viviparous, with mothers supplying nourishment to their embryos through a placenta.
Epiperipatus adenocryptus is a species of velvet worm in the Peripatidae family. This species is brown with a series of light brown arcs on each side forming a series of circles down its dorsal surface. Males of this species have 26 or 27 pairs of legs, usually 27; females have 28 to 30, usually 29. The type locality is in Minas Gerais, Brazil.

Mongeperipatus solorzanoi, also known as Solórzano's velvet worm, is a species of velvet worm in the family Peripatidae. This species is the largest known velvet worm, reaching 22 cm in length. This velvet worm is found in the Caribbean coastal forest of Costa Rica.
