====== Euperipatoides sp. ====== {{ ::onychophora.jpg?200|}} Clade : Panarthropoda Phylum : Onychophora Order : Euonychophora Family : Peripatopsidae //Common name//: velvet worms NCBI:txid[[https://www.ncbi.nlm.nih.gov/Taxonomy/Browser/wwwtax.cgi?id=27570|27570]] Onychophora are the accepted sister group of arthropods. Nelson (2018) analyzed the CYPome of //Euperipatoides rowelli//, and reported the presence of a CYP51 (sterol 14-demethylase) that is absent from nematodes and arthropods, a CYP20 and a CYP26, along with representatives of the four usual CYP clans. No conserved CYP302, CYP314, CYP306, but two distant CYP315-like sequences and a CYP18-like sequence are found. A {{ ::euperipatoides.fasta |selection}} of 27 full length sequences from //Euperipatoides kanagrensis// and //Euperipatoides rowelli// is presented in FASTA format. This does not represent the full CYPome of velvet worms. Nelson (2018) estimates the CYPome size to be 89.
