Re: Tambja or Roboastra ? from Indonesia

Concerning message #16009

Dear Bill,
I am also very confused with these species. I would like to have this specimen in order to dissect it since I could only check specimens from Guam. Nevertheless, what I can confirm is that T. tentaculata is phylogenetically very close to Roboastra species, since in all my morphological and molecular analysis there is a clade composed of Roboastra + Tambja tentaculata (submitted). Thus, the large and dorso-laterally grooved oral tentacles seems to be a very good character for this clade.

Regarding the specimen from Indonesia, I am not very sure if it is T. tentaculata. In this case, the colour of the gill, the rhinophores and the oral tentacles are quite different from it. T.tentaculata lacks blue pigmentation since the whole gill, rhinophores and oral tentacles are green.

My analyses also show that Tambja Burn, 1962 is not a monophyletic genus.

Best regards
Marta Pola

Dear Marta,
Thanks for your message. I must say it looks different to me. I guess I will leave it with T. tentaculata at the moment so it doesn't get lost among the 'unidentified'
Best wishes,
Bill Rudman
