Material examined

MARTINIQUE • 1 ♂; Rocher du Diamant; 14°26.7ʹ N, 61°02.3ʹ W; depth 4–10 m; 14 Sep. 2016; st. AB123; MNHN-IU-2016-1069 • 1 ♀; Trois Rivières; 14°27.5ʹ N, 60°58.2ʹ W; depth 17–19 m; 9 Oct. 2016; st.

AD286; MNHN-IU-2016-1195/ MK411078 • 1 ♂; Anse Couleuvre; 14°50.4ʹ N, 61°13.4ʹ W; depth 7 m; 1 Oct. 2016; st. AB463; MNHN-IU-2016-1382.

Remarks

This is the first record of this species from Martinique, only from the Caribbean coast. Anoplodactylus petiolatus subsp. hedgpethi was originally proposed by Băcescu (without designating type material) in order to mark the difference between the West Atlantic material described by Hedgpeth (1948) and Mediterranean/Black Sea material. Differences noted by Băcescu include thinner legs, different propodal armature of the propodal sole and the longer coxae 2 of the fourth legs. In this regard, our material seems to be similar to Hedgpeth’s material.

Distribution

Widespread in Atlantic: West Atlantic (off New York state, North Carolina, Georgia, Bahamas, Gulf of Mexico, Caribbean, Guyana, Surinam, French Guiana, Brazil, Uruguay, Argentina), East Atlantic (northern Norway, Northern Sea, English Channel, British Isles, Irish Sea, Celtic Sea, Galicia, Portugal, Gibraltar region, West African Atlantic, Cape Verde, Azores). It is also recorded from the entire Mediterranean, Marmara Sea and Black Sea. There are additional records from India and Chile.

Depth range

4–1520 m; one record at 4825 m potentially linked to sampling contamination ( Child 1982b).
