Dayrat (2010) writes that it is possible that there are several species under the name P. erythraeensis.
The Sea-Slug Forum has a picture of a specimen from Eilat, Israel, Read Sea which has brown rhinophore clubs, whilst Medslugs has a picture from Saint John's Reef, Egypt, which has translucent tan rhinophores, just like the 3 pictures in Dayrat (2006), and like the picture in IPN page 166. Let me quote the IPN description:
"This species differs from other Indo-Pacific Paradoris in having a yellowish to white body with a few black spots scattered over the dorsal surface and with opaque white markings on elevated tubercles."
