This species is as Eubranchus mandapamensis in IPN at page 354, let me quote:"Eubranchus rubropunctatus is a synonym."
NUDIPIXEL writes "Eubranchus mandapamensis (Rao, 1968) Also known as: Eubranchus rubropunctatus, Eubranchus madapanamensis"

"See discussion [message #22443] as to whether this is a synonym of Eubranchus mandapamensis."
Very similar in the colour pattern are:
Eubranchus mandapamensis which differs by the spaced annulations on the rhinophores and
Eubranchus cf. mandapamensis (Rao, 1968) which has no spaced annulations on the rhinophores and
Eubranchus cf. rubropunctatus which differs by the smooth rhinophores
let me quote Bill Rudman:"While it is possible that one species could have this degree of rhinophoral variability I can't think of an example. At this stage I suggest we take a conservative approach and keep the three rhinophore types separate until we know more about the anatomy and variability of this species or group of species."
I will keep the specimens with papillae scattered over the rhinophores as Eubranchus rubropunctatus, and if there turns up a specimen with spaced annulations on the rhinophores, I will post this as Eubranchus mandapamensis!
On 15 July 2011 sent Gordon Tillen pictures of a specimen with annulate rhinophores and a similar colour pattern, I posted it as Eubranchus cf. mandapamensis (Rao, 1968).
Many phantastic shots of Eubranchus rubropunctatus are at Jun Imamoto's website umiushi,
and one more picture of a specimen with annulate rhinophores is at the umiushi-zukan website without information on the location.
