Is this Pseudobornella orientalis?

October 20, 2005
From: XiKun Song

Dear, Bill
I am a postgraduate student at Xiamen University. Two undergraduates and I are taking a great interest in the taxonomy, morphology, distribution and larval metamorphosis of nudis. We choose Sakuraeolis enosimensis as our research model as it has a relatively broad distribution in China [messages #14610; #13615 ]

Locality: Xiamen, China. South China Sea. Depth: 1 m - 3 m. Length: All about 1 cm. 15 April 2005. Intertidal, fouling colonies. Photographer: Qin Ji

While doing this work we found a batch of nudis in marine fouling colonies, including what we think is an adult Pseudobornella orientalis. At last, I am wondering whether this is a new records for mainland China?

Thank you!

Dear Song,
It is a bit hard to see the actual shape of the body, but I can see a long coiled papillae branching off the rhinophore sheath, which is rather characteristic of the species. In the lower right close up we can see eggs aranged in a spiral inside an egg case. Is this any thing to do with Pseudobornella, or is just something the animal was crawling on?
Best wishes,
Bill Rudman
