In 2009, this species had only been found off South Africa, in False Bay off Windmill Beach, in at least 10 m of water. It appears to be endemic.
Pierre's armina grows up to 70 mm in length. It is a black-bodied nudibranch with raised white longitudinal ridges. The edge of the mantle is yellow and the foot is pinkish with a yellow margin. It has small ridged rhinophores, which are close together at their base.
Pierre's armina burrows in sand and feeds on the purple sea pen, Actinoptylum molle.
