Hypselodoris rudmani from sthn Queensland?

Concerning message #17554:

Hi Bill,
This may be a shot in the dark but, I found this animal in June 2006, and I find myself in a similar situation to Colin. If this animal is Hypselodoris rudmani then it is a long way from "home". I have spent quite some time trying to id it. The closest I have come is one of the animals in Colin`s message #17554. It is possibly a color form of H. maculosa, but to me it does not fit H.maculosa (banding on the rhinophores). What do you think?

Locality: Shag Rock, Point Lookout, North Stradbroke Island., 8 metres, Queensland Australia, Pacific ocean, 03 June 2006, rocky reef with sponges, hard & soft corals . Length: 15mm. Photographer: Bruce Wilkie.

PS. The other animal in the photo I think is Bullina lineata.
Many Thanks,
Bruce Wilkie.

Note added 5 June 2007: This is H. sagamiensis see message #19985.

Dear Bruce,

I'll do the easy bit first - yes the little bubble shell is a juvenile Bullina lineata.

As to the Hypselodoris. I feel a bit of failure not being able to identify a species named after me with certainty, but I would hesitate to say that this is H. rudmani - but then again it definitely has similarities to the animal in Colin's message which you refer to. H. rudmani was described from the NE coast of South Africa so it most probably has a wider distribution in at least the Indian Ocean. Perhaps Terry Gosliner or Rebecca Johnson could give us their opinion.

Best wishes,
Bill Rudman
