This species occurs primarily in the north-west Indian Ocean from the central Red Sea to Somalia; there is a separate population off South India and Sri Lanka; a further population may occur off the north of Madagascar (RÃ¶ckel et al.
1995). However, the Madagascan populations need verification, since these have not been confirmed since 1995; therefore these records are questionable (G. Raybaudi pers. comm. October 2011).
The EOO, AOO and number of locations exceed the thresholds for criteria B1 and B2 by a considerable margin.
