Unidentified Haminoeid #15
 
Unidentified Haminoeid #15
Maximum size:  4.5 mm.

Identification:  This species has a moderately thick shell with more prominent spiral striae on its apex and base than in Unidentified Haminoeid #13. The animal is translucent-brown patterned with clusters of compact white rosettes separated by irregular rings of red-brown flecks. Younger animals have a yellow background. It may be distinguished from Limulatys muscarius by its more compact rosettes.

Natural history:  Unidentified Haminoeid #15 is a rare species found in rocky habitats from < 1 to 5 m (< 3 to 16 ft). It occurs at moderately protected to moderately exposed sites. It shows a diurnal activity pattern when held in dishes.

Distribution:  Maui.

Taxonomic notes:  This species was formerly listed as a color form of juvenile Limulatys muscarius and its shells may be difficult to distinguish from shells of that species (pending further work). It was first recorded in Hawaii from Kapalua Bay, Maui by CP on April 22, 1996.
