What is "neoophora"

Neoophora is a group of flatworms with ectolecithal eggs, i.e., yolk ist not present in the egg, but rather secreted by accessory organs called vitellaria or yolk glands.

The monophyly of Neoophora is disputed, since some recent molecular studies indicated that the most basal order, Lecithoepitheliata, is more closely related to Polycladida, a non-neoophoran order, than to other neoophorans.
