Ectyonopsis is a genus of demosponges in the family Myxillidae. They are mostly known from the waters surrounding Australia and from the Southern Ocean.
== Description == This species was originally created for Ectyonopsis ramosa, an Australian species with acanthostyles (spiny styles (spicules with end pointed and the other rounded)) and acanthostrongyles (spiny strongyles (megascleres with both ends rounded)) that form a choanosomal isotropic structure. The genus Ectyonancora, which contained two South African species with acanthostyles, acanthostrongyles, ectosomal tornotes (spicules with both ends sharply pointed), and isochelae spicules (spicules with both ends alike) with protruding processes, was later synonymised with this genus.
