Chromodoris joshi from Bali

From: Mirjam Broos

Dear Bill,

I have a lot of pictures of 'blue' Chromodoris species. Some of them trouble me a lot. I'm really not sure I have identified them well.

I hope the ones in this message are Chromodoris joshi. Do you agree?

Dear Mirjam,

Although this has no blue, it is best lumped with the other black-lined species such as C. quadricolor and C. elisabethina. I tend to call this colour group the 'C. quadricolor group' so we don't get confused with the 'blue chromodorids' - mainly of the genus Hypselodoris found in the mediterranean and nearby Atlantic.  Your animal is indeed C. joshi. The absence of blue colouration and the white granular spots all over the mantle are good characters of this species.

Best wishes,
Bill Rudman
