Halgerda willeyi? from Philippines

From: Fredy Brauchli

Hello Bill

I am a Swiss scuba diver and hobby photographer and I like sea slugs very much.

In April this year I found on the island of Negros (Philippines) at a place called "Broccoli" Reef a specimen which looks similar to Halgerda willeyi. It is a small animal of about 8 - 10 mm.

Can you identity this slug?
Thanks very much for your help.
Kind regards from Switzerland

Dear Fredy,
I am pretty sure this is Halgerda willeyi. The papillae on its back, where the ridges join, are very elongate but I think this is a juvenile character. There are a number of people working on Halgerda at the moment so I am sure we will hear from them if I am wrong.

Best wishes,
Bill Rudman.
