Thordisa
sp. #14

 
Thordisa sp. #14
Maximum size:  about 13 mm.

Identification:  This is a yellow species with white branchia and mottled rhinophores. The center of the notum is decorated with a series of dusky patches.

Natural history:  The one known Thordisa sp. #14 was found at a depth of about 4 m (12 ft) crawling in fine sediment near rocks.

Distribution:  Big Island.

Taxonomic notes:  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.
