Eoperipatus is a genus of velvet worms in the family Peripatidae.[1] These velvet worms have been reported from locations throughout Southeast Asia, including Malaysia, Singapore, Thailand, and Vietnam.[2] This genus exhibits lecithotrophic ovoviviparity; that is, mothers in this genus retain yolky eggs in their uteri.[3]

Description
editThe number of legs in this genus varies within species as well as among species and ranges from 22 pairs (in E. butleri)[4] to 25 pairs (in E. horsti and E. weldoni).[5] In this genus, the crural tubercles form a single complex united by a dermal fold on each leg of two pregenital leg pairs. Males in this genus feature a single and medial anal gland opening on a pad in front of the anus. The male also features a circular pit on each quadrant of the genital pad, which is divided by a cruciform genital opening.[6][7][2] The female genital opening is a transverse slit. Each leg features two distal foot papillae, one anterior and one posterior.[2][6][5][8]
Species
editThe genus contains the following described species:[2]
- Eoperipatus butleri Evans, 1901
- Eoperipatus horsti Evans, 1901
- Eoperipatus totoro Oliveira et al., 2013
- Eoperipatus weldoni Evans, 1901
Eoperipatus sumatranus (Sedgwick, 1888) is considered a nomen dubium by Oliveira et al. 2012.[9]
In addition to these species, an undescribed species is known to occur in Thailand.[2][6] Furthermore, reports of Eoperipatus in Borneo and an unidentified velvet worm in central Vietnam, north of the known distribution of Eoperipatus totoro, may represent still more undescribed species of Eoperipatus.[2]
