Remarks

Martinique specimens are very similar to those described by Child (1977b), though the cement gland tubes are situated more proximally on the femorae (at about mid-length). The tubes are not arcuated in the present material; however, this character is known to be strongly variable ( Müller & Krapp 2009). All specimens were collected on the Caribbean coast.

Distribution

Anoplodactylus arcuatus is known from the Caribbean ( Curaçao, Barbados) and the Gulf of Mexico (Loggerhead Keys, Florida).

Depth range

Anoplodactylus arcuatus is known to dwell between 2.5 and 18 m. The present material was sampled between 10 and 56 m.
