Geographical Distribution. — Thus far, this species is known only from the Maui in the 
Hawai’ian Islands. 
Etymology.— The name pittmani honors Cory Pittman who has been intensely studying the 
Hawai’ian opisthobranch fauna for nearly two decades and, together with Pauline Fiene, has doc¬ 
umented the diversity of this insular fauna. Cory has discovered many new taxa, including the 
species described here. 
Natural History.— This species has been found in fine sand basins and burrowed in Hal¬ 
imeda kanaloana beds in 3-17 m depth. No prey items were found in the gizzard and no other 
information about its feeding ecology is known. This species produces a lozenge-shaped to spher¬ 
ical, white egg mass containing a tangled egg string. The mass has a sticky surface and acquires a 
coating of strongly adherent sand. Hatching of veliger larvae occurs in 5-6 days in the laboratory.
