''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 * ''Peripatops ...
