The identity of Homoiodoris novaezelandiae

November 10, 2006
From: Bill Rudman

The message today from Kimberley Seaward [#18266 ] concerning Hoplodoris nodulosa is an opportune occasion to post this photo of it from New Zealand, kindly sent by Michael C. Miller. In New Zealand this species was known as Homoiodoris novaezelandiae Bergh, 1904 until Miller's review (1991) which showed that it was a species of Hoplodoris. On the evidence then available it was considered distinct from the eastern Australian Hoplodoris nodulosa. However, in Fahey & Gosliner's revision of the genus (2003), H. novaezelandiae is considered to be anatomically identical to H. nodulosa.
