authors consider the Hawaiian population to be Hypselodoris whitei (Adams &
1850) rather than H.
maridadilus (restricting the latter to the Indian Ocean). See
the See Slug
Forum for further discussion. Described from East Africa, its
scientific name comes
from the Swahili
word "maridadi" which means "beautiful." It's referred to as the
"magenta-striped nudibranch" in Hoover, 1998 & 2006. It was
probably first reported from Hawaii in Eydoux and Souleyet, 1852 (as Doris lineata).
