Hypselodoris tricolor

(Cantraine, 1835)
This species name is also known as Hypselodoris midatlantica

Debelius & Kuiter (2007: 113) have explained it nicely under Hypselodoris midatlantica: “Usually referred to Hypselodoris tricolor, but according to Gosliner the species in the original description of Doris tricolor is unidentifiable and instead to use Hypselodoris midatlantica Gosliner, 1990.”
