We saw at least five of these between 1978 and 1985, all at night at Pupukea, Oahu, or Puako, Hawaii. All were in small ledges or caves at depths of about 9 to 12m. The genus is uncertain. We originally had tentatively considered it a Sclerodoris because of its irregular ridged and bumpy surface and its relative rigid texture, but its anatomy was not examined to verify this.
