Chromodoris hintuanensis or R. pulchella?

May 10, 2003
From: Asther M. Lau


Hi...
Could these be a Chromodoris hintuanensis or Risbecia pulchella? I think it fits the latter.

The upper two pics were taken by one of my club members, Lim Eng Hoo.

I am still not quite sure what the lower picture is.

Please help to identify.
Thank you!

Dear Asther,
C. hintuanensis is easily identifiable by the few yellow spots which are ringed with purple. But one of the best ways of identifying a species of Risbecia is the trailing behaviour the animals in both the upper photos are exhibiting. These are Risbecia pulchella. So is the animal in the lower photo. Its widened 'veil' at the front of the head is an indication it is a Risbecia and the yellow spots, white line on rhinopores, and purple smudges on the mantle are all characters of R. pulchella.
Best wishes
Bill Rudman
