Nembrotha nigerrima

Bergh, 1877
This species name is also known as Nembrotha kubaryana

Comment from Dr. Marta Pola: This species is highly variable but the tip of the rhinophores and the oral tentacle are always orange. The color of the pustules and the gills may vary between green and orange. There are also specimens with lines rather than pustules.

Comment from Dr. Marta Pola: Nembrotha kubaryana is a junior synonym of Nembrotha nigerrima, which is the type species of the genus.
