Glossodoris dendrobranchia

I described a specimen of this species as 'Glossodoris sp. A' in 1986, but was not willing to name it from a single specimen. This second specimen found by Jim Cruise (see message below), seems to confirm its nondescript pinkish brown colour and general body shape. It is one of the 'G. atromarginata group' of species with a high, very rigid muscular body, with a narrow radular ribbon. In Jim Cruise's photo you can see paler translucent patches along the rounded mantle edge which mark the position of the mantle glands. The radular morphology is quite similar to that of Glossodoris dendrobranchia which is also known from only a few specimens. I suspect this is a good species but more specimens are needed before we can confirm its status.
