Ardeadoris scottjohnsoni
Bertsch & Gosliner, 1989
 
Ardeadoris scottjohnsoni
Maximum size:  30 mm (Gosliner, et. al., 2008).

Identification:  This species has a soft, translucent-white body with an opaque-white submarginal band. The crenelate mantle edge overhangs slightly and has a pale gold marginal line. The rhinophores are black with a thin white vertical line on the anterior face and the gills are white basally with the distal two-thirds black. It is sometimes confused with Hiatodoris fellowsi which is also white with black gills and rhinophores. The latter species, however, has a firm body and lacks the gold marginal line.

Natural history:  Ardeadoris scottjohnsoni is rarely seen by divers on Maui but appears to be more common on Oahu. It may be found under rocks or in the open in rocky areas at moderately protected to exposed locations. It's been recorded at depths of 5-20 m (16-65 ft) and vibrates its gills.

Distribution:  Big Island, Maui and Oahu: also known from Okinawa.

Taxonomic notes:  This is the species that Bertsch and Johnson, 1981 listed as Chromodoris sibogae, Berge, 1905a. In the 5th printing, Hoover, 2006 refers to it as "Scott Johnson's nudibranch." It was first recorded in Hawaii from Kahe Point, Oahu by Terry Gosliner in July, 1973 and was named for Scott Johnson.
