the experts have no consens whether
Lobiger viridis Pease, 1863 is a synonym of Lobiger souverbii P. Fischer, 1856 or not
there is the consens that both species might have the same colour variants (with blue lines or without),
some scientists (Terrence M. Gosliner, William B. Rudman, Kathe R. Jensen, et al.)
see Lobiger viridis as a species of the tropical Indo-Pacific and
Lobiger souverbii as a species of the tropical Western Atlantic Ocean and of the Eastern Pacific Ocean.
Kathe R. Jensen writes at the Sea Slug Forum:
"It is possible that it could be one "world-wide" species, but in that
case a number of genetically isolated populations seem to occur. This might
something for the molecular biologists to look into."
Dr. Richard C. Willan sees one world-wide species, just as NUDIPIXEL
Jörger, Stöger, Kano, Fukuda, Knebelsberger & Schrödl (2010).
