We know so little about many of these animals and their normal distributions that it's not possible to make the assumption that this species is a recent arrival in Indonesia. I would suspect this species is widespread throughout the Malayo-Indonesian Archipelago and the central Pacific. At present we are recording the distribution of photographers as much as anything. I am afraid that we wont be able to make sensible judgements on whether 'new locality data' really represents a recent change in an animal's geographic distribution until we know a lot more about existing distributions.

Dear Dr. Rudman,
This was spotted on September 12th at Lembeh Straits [northern Sulawesi, Indonesia] in 8m meters of water on tiered rocks with light coral and sponge cover. I have not been able to identify it and was hoping you could help?
Length is approx 6 cm.

This is an unnamed species of which I have on the Forum as Philinopsis sp. 1. The previous records on the Forum are from Okinawa, so this find of yours certainly increases its known distribution.

Last week I went to Yonaguni Island located far western side of Yeyama Islands in Okinawa, Japan. Yonaguni Island is about 110km only from Taiwan as well.
My friend found a animal and show me while fun diving in this island. Is this a Chelidonura punctata? I'll be happy if this mail help your study a little.
data: 13 Jan 2002 water temp 23centigrade depth 21m on the rock, length 12mm

This is a very interesting find. I have seen a photo of this animal before but can't remember where. It is probably a species of Chelidonura or perhaps Philinopsis but I don't think it has a name. If you have any photos showing the animal from a different angle they would be very welcome.

How embarassing! I was sure I had seen this animal and spent an hour or two searching for it in books and other websites. Thanks for finding it for me

I found this opisthobranch at Ishigaki-Island, Okinawa, Japan. July, 2000.
Lengths: 50mm, 40mm
These animals crawled at very high speed on the top of the overhang. When I touched one, it put out purple ink like a sea hare. Could you tell me what kind of opisthobranch is this?

I am pretty sure that this is a new species of Philinopsis (Family Aglajidae). Looking at the shape of the head I would guess that it has a long muscular pharynx like Philinopsis gardineri. The only other species of Philinopsis with a colour pattern of transverse lines is Philinopsis lineolata.
The purple ink you describe is unusual, as most aglajids produce a yellow ink, when they are disturbed, from a gland which opens into or near the anus. As you mention, Sea Hares are the only sea slugs I know that produce a purple ink.
This is a very interesting, and beautiful, new find
