Dear Dr. Rudman and Mike Greenemeier
Concerning Mike Greenemeier's message #13508:

I think this animal is very similar to Diaulula greeleyi (MacFarland, 1909). Marcus and Marcus (1967) recorded this species in the coast of Florida.

For more information see:

  • Camacho-García, Y. and Valdés, A. 2003. Caryophyllidia-bearing dorid nudibranchs (Mollusca, Nudibranchia, Doridacea) from Costa Rica. Proceedings of the California Academy of Sciences, 54: 65-79.

Best wishes,

Dear Alma,
Thanks for drawing my attention to this paper. I had looked at Marcus's descriptions of Peltodoris greeleyi and hadn't been able to convince myself that it was the same thing. I guess I was looking for a clear description of the high rhinophore sheaths which to me seem a very chracteristic feature of the species.

Concerning the rhinophore sheaths, I am puzzled by some comments in Camacho-Garcia & Valdés (2003) where they transfer this species to Diaulula and consider the East Pacific Peltodoris nayarita Ortea & Llera, 1981 to be a synonym. They state 'the species [P. greeleyi] is transferred to the genus Diaulula due to a combination of features: ...... the low rhinophoral and branchial sheaths, ......' and yet later they say 'D. greeleyi is also different from D. aurila in radular morphology ..... the presence of high rhinophoral and branchial sheaths ......'. It is not clear from that whether D. greeleyi has high or low rhinophoral sheaths, and if high sheaths are considered a character of Diaulula, how is it that one species can have high sheaths and the other low?
Best wishes,
Bill Rudman
