|Maximum size: about 13 mm (estimated from photos).
This species ranges from greenish-brown to yellow. The rhinophores, gills, cephalic
tentacles and foot are tipped with dark purple.
is a moderately rare species found in moderately protected to moderately exposed rocky habitats and in Halimeda kanaloana beds at depths of 3-15 m (10-50 ft). When offered a piece of the blue bryozoan eaten by Tambja morosa, a young animal appeared to show feeding motions.
Big Island and Maui: widely distributed in the western & central Pacific.
It was first recorded in Hawaii from Makena, Maui by PF on June 26, 1998 and was known as Tambja amakusana until Martadoris was erected by Willan & Chang, 2017. There's some question about whether the Hawaiian population is this species or Tambja kava.
