[[File:Eoperipatus_totoro.jpg|thumb|''[[Eoperipatus totoro]],'' a basal member of [[Peripatidae]]]]
Living velvet worms are divided into two families: [[Peripatidae]] and [[Peripatopsidae]]. These diverged around 274 million years ago during the [[Late Devonian]] and have since diversified.<ref name=":12">{{Cite journal |last1=Murienne |first1=Jerome |last2=Daniels |first2=Savel R. |last3=Buckley |first3=Thomas R. |last4=Mayer |first4=Georg |last5=Giribet |first5=Gonzalo |date=2014-01-22 |title=A living fossil tale of Pangaean biogeography |journal=Proceedings of the Royal Society B: Biological Sciences |volume=281 |issue=1775 |pages=20132648 |doi=10.1098/rspb.2013.2648 |pmc=3866409 |pmid=24285200}}</ref> Within Peripatidae, the genera [[Eoperipatus]] (found in [[Southeast Asia]]) and [[Mesoperipatus]] (found in [[Gabon]]) were the most basal, while the rest of the group is found in tropical regions of the [[Americas]].<ref name=":12" /> On the other hand, Peritpatopsidae can be divided into two main [[clade]]s.

Below is a [[genus]]-level [[cladogram]] of velvet worms. Note that this phylogeny doesn't analyze every species and lumps most peripatids into [[Neopatida]], as many [[Peripatidae]] genera are [[paraphyletic]].<ref name=":05">{{Cite journal |last=Giribet |first=Gonzalo |last2=Buckman-Young |first2=Rebecca S. |last3=Costa |first3=Cristiano Sampaio |last4=Baker |first4=Caitlin M. |last5=Benavides |first5=Ligia R. |last6=Branstetter |first6=Michael G. |last7=Daniels |first7=Savel R. |last8=Pinto-da-Rocha |first8=Ricardo |date=2018 |title=The 'Peripatos' in Eurogondwana? – Lack of evidence that south-east Asian onychophorans walked through Europe |url=https://bioone.org/journals/Invertebrate-Systematics/volume-32/issue-4/IS18007/The-iPeripatos-i-in-Eurogondwana--Lack-of-evidence-that/10.1071/IS18007.full |journal=Invertebrate Systematics |volume=32 |issue=4 |pages=840–863 |doi=10.1071/IS18007}}</ref> As of 2023, there are around 232 total living species, meaning this phylogeny should eventually be updated.<ref name="Oliveira 2023" />{{clade|{{clade
