I collected one specimen of sea slug last week there I think is Navanax aenigmaticus because there are very similar animal photos on the Navanax aenigmaticus page. The animal was collected in Conchas Beach, Cabo Frio, Rio de Janeiro, Brasil. (Unfortunately I haven´t any photo of this animal)
Has this species been recorded in my country? Can I confuse Navanax aenigmaticus with another similar species?

Navanax aenigmaticus has not been recorded from Brasil under that name but Ernst Marcus described a species Chelidonura evelinae from Sao Paulo [Marcus, 1955) which is clearly the same species. So I guess if its in Sao Paulo it would not be surprising to find it also in Rio de Janeiro.
If you animal is similar in shape and colour to the animals in the Forum then I think you can be fairly certain that you have correctly identified it.
