Material examined
MARTINIQUE • 1 ♂; Baie de Fort-de-France; 14°36.1ʹ N, 61°04ʹ W; depth 0–1 m; 29 Sep. 2016; st. AM034; MNHN-IU-2016-875 • 1 ♀; same collection data as for preceding; MNHN-IU-2016-876/ MK411186 • 1 ♂ ov.; same collection data as for preceding; MNHN-IU-2016-1152/ MK411065 • 1 ♂; same collection data as for preceding; MNHN-IU-2016-1328.
Remarks
This species is widely distributed through the Indian Ocean, with some records in the eastern Mediterranean (Arango & Maxmen 2006). On the other hand, records of this species in Atlantic are rare. It may have been found near the Azores, though the record is unusually deep for the species, and Arnaud (1974) mentioned that the sampled female was “close to A. digitatus, without being identifical” without further explanation. The species was already known from Martinique, only recorded from the port of Fort-de-France (Bourdillon 1955; confirmed by the present study).
Distribution
Tropical Indo-Pacific (Indonesia, Madagascar, India, Myanmar, Malaysia, Oman, Singapore, Great Barrier Reef), Eastern Mediterranean and Marmara Sea. Some records from Martinique and Azores (?).
Depth range
Intertidal to 75 m (most records between 0 and 5 m); one record of Anoplodactylus cf. digitatus in Arnaud (1974) at 600 m.
