Hypselodoris zephyra is characterized by oblique dark blackish lines, and orange/red rhinophores with opaque white tips. The gills are edged with orange/red, and have diffuse white spots on the outer side. This shot shows a 2 mm juvenile specimen identfied by Dr. Richard C. Willan, he writes:
"I'm usually very cautious about identifying tiny juvenile nudibranchs because they differ so much from adults. However this one is quite straightforward. It's a tiny juvenile Hypselodoris zephyra. I call it that because it's a common species and I have seen lots of individuals of all sizes."
Pretty similar are
Hypselodoris maritima which differs by its longitudinal black lines, and by a blue submarginal mantle border, and a yellow band inside,
Hypselodoris nigrostriata which differs by its gills, triangular in cross-section, and by the rhinophores which lack the opaque white tips, the gills also lack the white spots. The black lines are parallel rather than oblique. The background colour of the body has a bluish or purplish tinge.
IPN writes on Hypselodoris nigrostriata: "Known from the western Indian Ocean of Tanzania, the United Arab Emirates, and the Red Sea."
NUDIPIXEL had additional pictures from the eastern Indian Ocean of Thailand, Indonesia, and from the western Pacific Ocean of Indonesia, Taiwan, and the Philippines, the website NUDIPIXEl is down, the pictures are gone.
This species was posted on 13 January 2010 at these websites as Hypselodoris zephyra  Gosliner & Johnson, 1999.
It is a convention in malacology to use the first initials of authors with the same family name to distinguish between them,
that is R.F. Johnson for Rebecca Fay Johnson and S. Johnson for Scott Johnson. I changed the authorship on 8 May 2016.
