Trapania cf. brunnea from Marshall Ids

Note added 12 March 2008: This species has been named Trapania euryeia. 

Hi Bill,

It looks to me like this species from the Marshall Islands is Trapania brunnea. There is some variation in distribution of white and brown coloration on the body, and one of the specimens, e050a-1, has orange anterior tentacles.

Size range:
e050a-1 = 6mm,
e050 = 16mm long.

Dear Scott,
It is similar, but I wouldn't be surprised if it is a different species. The white patterning is much more prominent in your animals. The other point is that Trapania brunnea seems to be a southeastern Australian endemic. It has been found in both New South Wales and South Australia, which could be due to tropical currents, but it is also found in Tasmania and Victoria, which usually do not have tropical stragglers.

The radular morphology is a quite useful character in Trapania, but until we know a little about the anatomy of your animal I will be cautious and call it Trapania cf. brunnea.

Best wishes,
Bill Rudman.
