Remarks

This species is reported for the first time from Martinique, where it was only sampled on the Caribbean coast. The species is morphologically close to A. madibenthos sp. nov., with the same characteristic pectinated propodal spine; however, this species is much more elongated, with a wider separation between the lateral processes.

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.

Depth range

0– 34 m.
