I've not personally seen Noumea sp. 2 in the waters of Okinawa's main island and Atsushi Ono mentions (pers. comm.) collecting no specimens; only photos of the featured individual are available.
Atsushi considers the species to be very rare in the Keramas as he has seen and photographed only the single featured animal. Atsushi found the solitary animal between dead corals. Noumea sp. 2 is very similar to Noumea sp. 6 illustrated in Gosliner, et al. (2008, p. 248), found in Vanuatu, an island nation located in the South Pacific Ocean.
I've previously added another unknown Noumea, Noumea sp. 1, also collected from the Keramas by Atsushi.
