Hypselodoris lacuna has been recently described, published on 14 September 2018. It is characterized by an opaque white mantle with large translucent greyish round spots and irregular small blue/purple spots at the mantle margin, some of them are in the greysih spots. The rhinophores are translucent at the base followed by a white band, the upper half and the tips are orange.
This species is as Hypselodoris sp. 11 in IPN at page 270,
let me quote the description:" Body color opaque white with purple spots. Many of the spots are located in translucent circles on the notum. Gill and rhinophores tipped with red orange."
This specimen had been misidentified and was posted on 27 June 2006 at these websites as Hypselodoris sagamiensis (Baba, 1949) [Glossodoris] .
This species was posted on 26 November 2010 at these websites as Hypselodoris sp. C  Genus: Stimpson, 1855, and changed on 15 August 2011
into Hypselodoris sp. 03  Genus: Stimpson, 1855.
For some genera, such as Trinchesia was the alphabet almost through. I had to change the distinguishing alphabetic character into a number. I had chosen
2-digit numbers, even though '01' looks a little bit stupid, and now is only the genus italic written.
I changed it on 27 September 2018 into Hypselodoris lacuna  Gosliner & R.F. Johnson, 2018
Let me quote Epstein et al. (2018) on the etymology:
"This species is named Hypselodoris lacuna based on the translucent areas on the notum that resemble holes in the body wall."
