Anoplodactylus pectinus

Distribution Pantropical: Tropical West Atlantic (Caribbean, Gulf of Mexico, Florida), Indian Ocean (Madagascar, Indonesia), Easter Australia, Pacific Ocean (Philippines, Ryukyu Archipelago, Fiji Islands, Caroline Islands). It is possible that some of these records were mistaken with Anoplodactylus madibenthos sp. nov.
