Hypselodoris bertschi has a white body flecked with black-purple spots. The gills and rhinophores are translucent white, lined with orange tips and base. There has been some confusion in the naming of this species, and it is easily confused with Hypselodoris andersoni.
This species can reach a total length of at least 25 mm.
