Known only from the Hawaiian Islands, it was originally placed in the genus Sclerodoris, although the original authors (Bertsch & Johnson, 1982) had some doubts about palcing it in that genus. It has recently (Fahey & Gosliner, 2001) been moved to the genus Halgerda. It has the typical high body form and ridges of that genus and the ridges have prominent tubercles at their junctures. The body is translucent clear or pale yellow and the ridges are a deep yellow or orange yellow. The rhinophore clubs are brown with a whitish tip. The gill is light brown with white tips. There are also tiny, dark, perpendicular lines along the front of the foot and on the mantle edge. According to Scott Johnson this species is nocturnal.
