Hello Bill,
Im very excited at a recent discovery of mine at Bare Island, La Perouse. Sydney. I have been looking for any species of Doto in this area as I haven't seen any reports of them here before. Finally after a long time searching I have found what I think is a Doto sp and from extensive searches it appears that its undescribed, woohoo!!! It seems that this Doto that was sent in by Gareth Jones in 2001 is the closest I have come in finding a match however the rhinophores in the specimen pictured are totally black and the ones that im sending in are clear. I am trying to obtain more detailed and clearer pictures along with other observations. It is definatley associated with the hydroid pictured as i found the same species a couple of months ago in a different area of the island but when i was diving without a camera. Im very interested in doing further study of this species and if there is anything in particular that i could do in order to have it properly identified please let me know. I have included a photograph with a Doto and a white egg ribbon. Both times that I have found these nudibranchs was in the presence of the same egg ribbons. On this particular dive I found four seperate clusters of Doto on their hydroid colony and each cluster contained several white egg ribbons. Although I havent seen them laying yet I believe them to be from the Doto sp. I will endeavour to capture this on camera to add to the data base.
I am very keen to be involved in the study of this species and I believe it to be endemic to this area considering the different areas where I have found it and on separate occassions spanning months.
Locality: Bare Island, La Perouse, Sydney, 18 m, NSW, Australia, Botany Bay, 14 November 2008, Broken reef,. Length: 20 mm. Photographer: Nicholas Missenden.
Hope to hear from you soon.
Kindest Regards

Dear Nick,
This is Doto ostentus. When I got your message I wondered what had happened to the Fact Sheet for that species, because it is the 'common' Doto in New South Wales. When I looked I found a half-finished Fact Sheet dating from 6 years ago, so my apologies for raisng your hopes of a 'new discovery'. It is possible that this species, which was named from southeastern Australia 50 years ago, is the same as one of the other black-spotted species of Doto reported from the Indo-West Pacific but we need to learn more about those other species before we can be sure. The animal from New Zealand that your refer to seems to differ in having bllack rhinophores.
Best wishes,
Bill Rudman
