'''Ptychophorae''' is a suborder of [[Biology:Rhizostomeae|rhizostome]] jellyfish, identified in 2013 by Gershwin and Davie.<ref name=GershwinDavie>{{cite web|url=http://www.qm.qld.gov.au/~/media/Documents/QM/About%20Us/Publications/Memoirs%20-%20Nature/N56-2/qmn56-2-gershwin-davie.pdf|author1=Gershwin, L.  |author2=Davie, P.J.F. |name-list-style=amp |date=30 June 2013|title=A remarkable new jellyfish (Cnidaria: Scyphozoa) from coastal Australia, representing a new suborder within the Rhizostomeae.

The word Ptychophorae is said to be derived from the Greek {{transl|grc|ptychos}} (fold, leaf, layer) and {{transl|grc|phoras}} (bearing), in reference to the hooded rhopalia.<ref name=GershwinDavie/> The proper word for 'fold' in ancient Greek is however ''ptyx'' (πτύξ).<ref name="Liddell & Scott">Liddell, H.G. & Scott, R.

* There are 4 velar lappets per octant.
* There 2 asymmetrical ocular lappets per octant.
