Remarks

Müller & Krapp (2009) suggested that Anoplodactylus dauphinus and A. multiclavus are two junior synonyms of this species. The only specimen for which barcoding worked is a female (MNHN- IU-2016-877), meaning that it was not possible to validate its identification by the observation of cement glands. However, females attributed to this species are similar to identified males for all other characters (including length of the sole lamina, presence of a propodal heel, shape of the ocular tubercle, shape of chelae carrying teeth, constriction near the tip of the proboscis), which in turn fit with the descriptions of Stock (1954b) and Müller & Krapp (2009). In addition, both females were collected at localities where males of A. glandulifer were found. We are therefore confident in the attribution of the CO1 barcode sequence MK411187 to the species A. glandulifer .

This species is mostly known from the Indo-Pacific, although it has regularly been sampled in the Western Atlantic. This is the first record of this species from Martinique; the species was collected on the Atlantic and Caribbean coasts, and in the Baie de Fort-de-France.

Distribution

Pantropical: Tropical West Atlantic (Caribbean, Gulf of Mexico), Indian Ocean (Aldabra, Madagascar, Seychelles, Kenya, Oman, Malaysia, Singapore), Australia (Great Barrier Reef and Timor Sea), Southern China Sea ( Hong Kong), Pacific ( Samoa, Guam, Marshall Islands, Marianas Island).

Depth range

Intertidal to 78 m.
