Aeolidiella drusilla

See Glenys Greenwood's message for a discussion on the identity of Aeolidiella drusilla and Aeolidiella faustina.

Note added 21 Nov. 2007: To indicate there was some doubt about the identity of Australian specimens they were previously labelled  Aeolidiella cf. drusilla. However as discussed in a separate message [#21172] Miller (1971) described specimens of A. faustina and A. drusilla from New Zealand which clearly confirm that the Australian animal is A. drusilla despite earlier identifications as A. faustina.
