Distribution.

Arabian Gulf and Indian Ocean; Indo-West Pacific, from South China Sea to Australia ( Poutiers 1998 b; Robba et al. 2004). Records of fossils from the Early Miocene to Holocene in Indonesia, Japan, Malaysia, and Thailand ( Robba et al. 2004; Dharma 2005; Matsubara and Komori 2007; Raven and Vermeulen 2007).

Record in Thailand.
