Siphopteron brunneomarginatum from Taiwan

From: Todd Garthwaite

Hi Bill,
I came across another tiny specimen of what I'm guessing is Siphopteron flavum. The population explosion of Chelidonura amoena is as big as ever, and still holding strong. Naturally, I'd be most grateful if you could help me identify this nudibranch!

Site: 'Nudibranch Alley', (Dragon Cave Bay, N.E. Coast, Taipei County, Taiwan)
Date: 05 April 2002
Depth: 13.9 meters
Temp: 22 degrees C.
Size: approximately 2 - 2.5 mm.
Thanks again!

Dear Todd,
This is Siphopteron brunneomarginatum. It is similar to S. flavum but this species has a brown borders to the parapodia. It is known from Guam, Marshall Ids, and Papua New Guinea, so your find increases the known distribution of this species.
Best wishes,
Bill Rudman
