Thordisa albomacula
Chan & Gosliner, 2007
 
Thordisa albomacula
Maximum size:  30 mm.

Identification:  This dorid has an irregularly pitted notum with variably developed tentacular papillae. It varies from cream to violet brown. The bottoms of the pits are usually darker and there may be a variable amount of white flecking. Nearly all animals have a short white band extending forward from the branchia and the rhinophores are brown, tipped with cream flame-like markings. Young animals are smoother and may have marginal white spots.

Natural history:  Thordisa albomacula is a moderately rare species found in the low intertidal and subtidally to about 1.5 m (5 ft) at protected to moderately exposed rocky sites. Rarely, it occurs in Halimeda kanaloana beds at about 6 m (20 ft). Egg masses range from orange to pink (perhaps depending on diet?) and hatch in four to five days in the laboratory.

Distribution:  Maui, Niihau and Midway: widely distributed in the western & central Pacific.

Taxonomic notes:  First recorded in Hawaii from Hekili Point, Maui by CP on May 5, 1993.
