Chromodoris geometrica & C. conchyliata

December 20, 1998

Hi Bill,

Talking about Phyllidia mimics brings the subject to Chromodoris geometrica. I note that the 'Chromodoris geometrica' in Terry Gosliner's South African book has red gills and rhinophores. I've now seen quite a lot of the typical Indonesian ones, they have green rhinophores and gills and are probably
distinct.

Dear Bernard,
As you will see here, Chromodoris geometrica in the Western Pacific has greenish gills and rhinophores, although quite pale in some specimens. In the western Indian Ocean there is a similarly coloured species in which the gills and rhinophores are lined with red or reddish-orange and the pustules are often quite yellowish. It is possible that the western Indian Ocean "form" reaches the Indonesian Archipelago, but as yet I only know, as you do, of the greenish-gilled form.

I reported and illustrated the Indian Ocean colour form from Kenya in 1973 - my first publication on chromodorids! - as Chromodoris cf. geometrica and Nathalie Yonow (1984) described it from Sri Lanka as a new species, which she named Chromodoris conchyliata

Best wishes,
Bill Rudman.
