Hypselodoris bollandi is very similar in external appearance to the yellow spotted species of the previous genus Risbecia which was synomized by Johnson & Gosliner (2012) with the genus Hypselodoris : Hypselodoris pulchella, Hypselodoris godeffroyana and Hypselodoris imperialis.
Hypselodoris bollandi is characterized by a white body with 4-7 dark blue patches on each side, and a diffuse purple median region. The mantle is covered with irregular small yellow/orange spots. The rhinophores are translucent reddish/orange, the gills are translucent white with red/orange edging. The gills form a simple circle.

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.
