Peripatopsidae is one of the two living velvet worm families.[1][2]


The Peripatopsidae exhibit relatively many characteristics that are perceived as original or "primitive" with respect to the Peripatidae. They have between 13 and 25 pairs of legs, behind or between the last of which is the genital opening (gonopore). Both oviparous and ovoviviparous, as well as genuinely viviparous, species exist, although the Peripatopsidae essentially lack a placenta.[citation needed]


The distribution of the Peripatopsidae is circumaustral; in particular, they inhabit Australasia, South Africa and Chile.[3]


The family contains the following genera:[4]
