Remarks Anoplodactylus bahamensis is discriminated from Anoplodactylus micros by the conspicuously larger size of the specimens and the wider opening of the cement gland pores. We observed setae on the ventral side of the proboscis in both species (but not in all specimens), unlike observations in Müller & Krapp (2009) . Only one specimen was barcoded, a female. While it is not possible to confirm its identification using the cement glands, the specimen is similar to the male specimens regarding all available characters, including the propodal sole lamina and the dorsomedian tubercles on the lateral processes. This is the first record of this species in Martinique . The species was sampled at five different stations, four of them on the Caribbean coast, one (the barcoded female, MNHN-IU-2016-1264) on the Caribbean coast. Müller & Krapp (2009) mentioned that the species prefers sublittoral areas, where it is peculiarly abundant in sea-grass meadows. Fig. 20.
