 Distribution. Previously known from Red Sea, Madagascar and Mozambique Channel, Comoro Islands, Farquhar Islands, Cöetivy Islands, Mauritius, Saya de Malha Bank, Chagos Archipelago, Gorong Island, Timor, Biak I. and Hollandia, New Guinea, Ternate, Taiwan, Ishigaki-jima, Okinawa-jima, Amami-oshima, Ryukyu Islands, Palau Islands and Yap Island, Fiji Islands, Ellice Islands, Loyalty Islands, Tuamotu Archipelago, French Polynesia; intertidal to 48 m. Now also known from South China Sea; intertidal to 50 m.   
 Remarks. The species is unique among congeners from the Indo-West Pacific in having the pterygostomian flap with one or two spines on the anterior upper margin near the linea anomurica and in the Mxp3 merus having a strongly median spine on the flexor margin. Seven of the specimens examined (two males and five ovigerous females of MBM 150333 and MBM 150215) have two spines on the flexor margin, the distal of which is much smaller than the proximal one.
