Fernald's Aeolid

Cumanotus fernaldi

Misidentification (but good photos) in published field guides 1

Cumanotus fernaldi is one of two Cumanotus species in California - the other is still undescribed as of this writing, April 2018.

1) Behrens and Hermosillo, Eastern Pacific Nudibranchs (2005 and 1991).
According to Jeff Goddard, a photo of Cumanotus fernaldi is found in Behrens and Hermosillo, Eastern Pacific Nudibranchs (2005), Species #245, erroneously identified as Cumanotus sp. 1. Species #244 is actually the undescribed species. An earlier edition of this book (1991) misidentified it as Flabellina sp 1.

2) Lamb and Hanby, Marine Life of the Pacific Northwest (2005). Species MC357 on p. 269 "Burrowing Aeolid, Cumanotus sp 1" is actually Cumanotus fernaldi.

Another morphologically similar species, C. beaumonti, is not in California; it's an Atlantic species. Earlier papers often refer to C. fernaldi as C. beaumonti.
