Thordisa sp. #14
|Maximum size: about 13 mm.
is a yellow species with white branchia and mottled rhinophores. The
center of the notum is decorated with a series of dusky patches.
The one mature Thordisa sp.
#14 was found at a depth of about 4 m (12 ft) crawling in fine sediment
near rocks. The habitat of the potential juvenile was similar.
Distribution: Big Island and Maui(?).
It was first recorded in Hawaii from Honokohau Harbor, Big Island by Paul Okumura on
May 31, 2014. In its background color and dusky mid-line patches, it's
reminiscent of Thordisa sanguinea Baba, 1955 as illustrated on Bill Rudman's Okinawa site. However, the branchia (in both color and form) don't appear to match that species. (Note 1)

Observations and comments:
1: An ambiguous juvenile
photographed in 1996 may belong to this species. If that is ultimately
confirmed by further material, it was first been recorded in
Hawaii from Maalaea Bay, Maui by PF on May 3, 1996.
