Grows to about 40 mm. Densely pustulose mantle except in a median band behind the rhinophores where the pustules are often absent or very reduced in size. Colour normally a mottled brown or yellowish brown often with the median band being a darker colour than the rest of the mantle. It is common intertidally but is also found to about 8 m.

There are a number of other similar nodulose dorids which have recently been revised. See generic review of Hoplodoris. In New Zealand this species was known as Homoiodoris novaezelandiae Bergh, 1904 until Miller's review (1991) which showed that it was a species of Hoplodoris. On the evidence then available it was considered distinct from the eastern Australian Hoplodoris nodulosa. However, in Fahey & Gosliner's revision of the genus (2003), H. novaezelandiae is considered to be anatomically identical to H. nodulosa.
