Thorunna cf speciosus? from Japan
June 9, 2000
From: Atsushi Ono
Dear Bill,
Here are chromodorid photos of different individuals. They are very small, the UPPER PHOTO is 7mm long, the LOWER is 5mm long.
I found them at 5m depth on a coral reef in May and Oct. 1999, at Kerama Is. near Okinawa in Japan.
Is this color variation of Thorunna speciosus?
PS. I have sent a photo separately, of an animal I think is Thorunna speciosus from the area.
Sincerely,
Atsushi Ono

Ono, A., 2000 (Jun 9) Thorunna cf speciosus? from Japan. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/2466Note: Previously on the Forum as Thorunna cf. speciosus this is now named Thorunna halourga.
Dear Atsushi,
It certainly looks a bit like Thorunna speciosus but the white border all around the mantle edge is certainly different. It is possibly a species of Thorunna but we could only be sure if that by looking at its anatomy.
Best wishes,
Bill Rudman.
