Nembrotha? or Hypselodoris nigrostriata?

June 18, 2000
From: Clinton Bauder

I saw this slug in Milne Bay, Papua New Guinea last summer. At the time I ID'd it as Nembrotha lineolata but Erwin Koehler thinks it is probably Hypselodoris nigrostriata. It isn't the best photo as I grabbed from a still frame of video but I was hoping you could help with a more definitive ID.

Thanks!

Dear Clinton,
Erwin is right. It is what I'm calling H. nigrostriata. It is quite similar to the recently described Hypselodoris zephyra but in that species the gills are a uniform orange, and the lines on the mantle are usually parallel not diagonal as in H. nigrostriata.

[Clinton has a website called Metridium Fields which is well worth a look. It includes photos of a number of nudibranchs from Monterey, California.]

Best wishes,
Bill Rudman.
