Siphopteron quadrispinosum from New Caledonia

January 16, 2004
From: Bill Rudman

To accompany my discussion on Siphopteron quadrispinosum here is a record of the species from New Caledonia. This is the first time it has been reported from New Caledonia.
• Chenal de la Passe de Koumac, East side, New Caledonia, 20°40.4'S, 164°14.9'E, 26m, In lagoon, hard substrate 26 October 1993, 1 specimen, 3mm live alive. AM C200653

The animal was bright yellow with bright orange marks as shown in the photographs. Of particular interest are the transverse orange marks on the parapodia which can be seen on the right parapodia [in upper right photo] and on the left parapodia [in lower right photo]. These match the tranverse bands seen in the Japanese specimen in Nishina Masayoshi's earlier message.

I have posted a description of the radula in a separate message.

Best wishes
Bill Rudman
