Remarks :

Identification confirmed by David Behrens " Your Paradoris sp (upper photo) is definitely the same as our Paradoris sp. 10, but I am not sure about your second specimen (photo below), looks like it might different that any we have "
     According Bill Rudman " This species has been recognised by Dayrat (2006) as Paradoris sp. C "
    Under the name Paradoris sp. 10 in Nudibranch and Sea Slug Identification. Indopacific. 2015

Bibliographic data :

Like other species of Paradoris, the mantle tissue is packed full of opaque whitish spherules.
    This species looks like Paradoris sp. 2, but in Paradoris sp.4 the series of dark brown to black lines are transverse and running out to the mantle edge across the mantle skirt, not in Paradoris sp. 2
