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 .
