Dear Mickey,
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.
Best wishes,
Bill Rudman

Philinopsis sp. 1 from Sulawesi

September 24, 2003
From: Paul Whitehead

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.

Thanks
Paul

Dear Paul,
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.
Best wishes

Dear Hitoshi,
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.
Best wishes,

New Philinopsis from Japan

January 18, 2001
From: Rie Nakano


Dear Bill,

I found this opisthobranch at Ishigaki-Island, Okinawa, Japan. July, 2000.

Depth:13m
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?

Sincerely,
Rie

Nakano, R., 2001 (Jan 18) New Philinopsis from Japan. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/3547

Dear Rie,
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
Best wishes,
Bill Rudman
