Halgerda johnsonorum? at Pulau Aur, Malaysia

August 11, 2007
From: Yap Ting Wee

Hi Bill,
I found this species of Halgerda in Pulau Aur/Dayang, West Malaysia on 23 June 2007. I was told it was Halgerda willeyi, but it looks more like H. johnsonorum to me. Please help me to confirm which of this it belongs to.

Locality: Pulau Aur, 15m, West Malaysia, South China Sea, 23 June 2007, Hard Corals. Length: 2 inches. Photographer: Yap Ting Wee.

Dear Wee,

I haven't seem many illustrations of H. johnsonorum but it seems that that species has yellow lines only on the ridges and does not have the high ridges and tubercles found in your animal. I am pretty sure your animal is H. willeyi.

Best wishes,
Bill Rudman
