"Hypselodoris paradisa is named for the Greek word for paradise, referring to the tropical habitat of this species."
Pretty similar are:
Hypselodoris maculosa which differs by two orange bands on the rhinophore clubs,
Hypselodoris decorata which differs by an undulating brownish or purple mantle margin,
Hypselodoris yarae which differs by a broad orange marginal band, and
Thorunna australis which has a pale bluish or pink background colour, two longitudinal white lines, one on either side of the mantle and always one reddish band on the rhinophores.
The specimen of the picture #7 was misidentified and posted on 5 October 2018 at these websites as Thorunna cf. australis (Risbec, 1928) [Chromodoris],
I changed it on 15 September 2019.
