Chromodoris albopustulosa
(Pease, 1860)
 
Chromodoris albopustulosa
Maximum size:  30 mm (Gosliner, et. al, 2008).

Identification:  This species has a pale yellow mantle with white pustules and violet scallops along its margin. The rhinophores are brown with white lamellae and the gills are cream. The latter feature distinguishes it from the similar appearing Chromodoris vibrata.

Natural history:  Chromodoris albopustulosa is commonly seen on rocky bottoms from the low intertidal to 21 m (70 ft). It occurs in protected to exposed locations. It is usually nocturnal but may be found under rocks during the day or resting in the open on shaded cliffs. It has been observed feeding on a species of yellow sponge. The egg mass is pale orange-yellow.

Distribution:  Big Island, Maui, Oahu, Kauai and Kure: also known from the Marshall Islands.

Taxonomic notes: Scott Johnson suggested on the Sea Slug Forum that Chromodoris aureopurpurea, Chromodoris alius, and Chromodoris rufomaculata might be synonyms of this species. The name refers to the white pustules. It's referred to as the "purple-edged nudibranch" in Hoover, 1998 and as the  "white-bump nudibranch" in Hoover, 2006. It was first reported from Hawaii in Pease, 1860.
