Noumeaella isa
Maximum size:  8 mm.

Identification:  This is a translucent-cream animal densely flecked and reticulated with white. The rhinophores have papillae on their posterior faces and the cerata are more numerous than in the similar appearing Noumeaella rehderi.  In some animals, the white flecks may form irregular bands on the notum and there may be small dark spots in the basses of the cerata. (see photo)

Natural history:  Noumeaella isa is known from only three animals. The Maui animal was found in an algae wash from a silty Halimeda kanaloana bed taken at a depth of  6-9 m (20-30 ft). The Big Island animal was found at 4 m (12 ft).

Distribution:  Big Island, Maui and Midway: widely distributed in the Indo-Pacific.

Taxonomic notes:  It was first recorded in Hawaii from Midway Atoll by Terry Gosliner and PF in Sept., 1998.
