Peripatopsis
Peripatopsis is a genus of South African velvet worms in the Peripatopsidae family.[1][2] The number of legs in this genus ranges from as few as 16 pairs (e.g., in P. clavigera)[3] to as many as 25 pairs (in P. moseleyi) and varies within species when the number is greater than 18 pairs.[4] Velvet worms in this genus feature a last pair of legs (the genital pair) that is rudimentary or reduced in size, mainly in males.[4] 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.[5]
