Distribution and ecology. Widespread from the Western Indian Ocean to Hawaii (Núñez Pons et al. 2017). Only two species of Iotrochota have been recorded from Spermonde Archipelago, Iotrochota purpurea and Iotrochota baculifera Ridley, 1884 (de Voogd 2005). Our specimen was found in the north-west of Samalona Island, the Spermonde Archipelago; reef flat.
