Doris auriculatus

Müller, 1776

Ab van Lenten Discodoris Atromaculata l'Escala, Spain Canon 40D, 60mm 2.8, 2x DS160, Subsea +10 1/125, f/16, ISO 250

João Pedro Silva Peltodoris atromaculata

Ab van Lenten According to wiki we are using a synonym, same species?

João Pedro Silva Quite, but you have to understand there are valid, accepted synonyms and unaccepted ones, usually junor (described later). That is why we don't use the invalid synonyms, otherwise we could still use Doris auriculatus, the name Müller gave to Facelina auriculata in 1776. http://en.wikipedia.org/wiki/Facelina_auriculata

Ab van Lenten Ok, I see I need to read some more about this, thanks

Kirstie Knowles For those of us still getting up to speed with the taxonomy of these beasties, I find using WORMS (World Register of Marine Species) to be very useful (and user friendly to non-specialists). Obviously updates happening all the time but the WORMS editors are specialists themselves and pretty onto it.
