A large dark blue elongate species with yellow spots arranged in rows down the dorsum and in a row down each side of foot. Margin of foot and dorsum a lighter cobalt blue. Gills and rhinophores blue to black. Similar in appearance to H. ghiselini but that species differs in having a darker blue background colour and smaller more numerous spots of yellow and white on the mantle and foot. There are also small white spots as well. There are yellow spots on the rhinophore clubs and the inside of the gills, and no paler blue margin. Grows to about 60 mm.
