Halgerda wasinensis? from East Timor

March 17, 2004
From: Nick Hobgood


Dear Bill,
This little guy (~2cm) was found in 5-6 m water here in East Timor. I cannot find him in my field guides. Can you offer some help?
Thanks much

Dear Nick,
Any chance of a date and a few more locality details please? If we have this sort of information then the photos become a valuable bit of information.

I am afraid this is a bit of a mystery to me. Although there has been some excellent recent work on Halgerda we still have a lot to learn about the group. I guess it's a question of 'the more we know, the more we know we don't know'! One possibility is that this is a form of Halgerda wasinensis, but the white pustules around the mantle edge are quite reminsicent of Halgerda toliara, but that species doesn't seem to include forms with black spots.

We still have much to learn about these animals so at present I would tentatively identify it as H. wasinensis. Keep on the lookout for other colour forms, as any variations might help give us a clue to its identity
Best wishes
Bill Rudman
