is a rare species known from only a few animals. It's nocturnally
active and has been found under ledges and in small
moderately exposed to highly exposed habitats from 8-15 m (26-49

Big Island and Oahu.
some question whether this species is an Ardeadoris or Goniobranchus. However, it's similar to species with irregular white pustules that were moved to Ardeadoris in Johnson & Gosliner, 2012. It
was first recorded in Hawaii from Puako, Big Island by
Scott Johnson on
April 27, 1981.
