Family Pandalidae Haworth, 1825

Heterocarpus aff. ensifer A. Milne-Edwards, 1881 . Stn 32, Nuku Hiva, 380 m ( Fig. 3 c). R/V Marara , trap, Eiao, Fatu Hiva, Hiva Oa, Tahuata, Ua Pou, Nuku Hiva, 217–730m, mostly 300– 400m.

Remarks. Specimens photographed with the ROV have a large red lateral patch on the cephalothorax, a distinctive character of H. ensifer . This patch is also present in H. parvispinna De Man, 1917 , but this species has never been collected in the Marquesas, whereas H. aff. ensifer is common between 300–400 m ( Poupin 2005: 66, fig. 33). Heterocarpus ensifer has a worldwide distribution in the Atlantic, Indian Ocean and Central Pacific (Hawaiian Is, Kiribati, and Marquesas). Heterocarpus ensifer is probably a complex of species ( Crosnier & Forest 1973: 192, Chace 1985: 26, and Crosnier 1988: 71). According to Crosnier (1988) specimens from the Atlantic and southwestern Indian Ocean are referable to H. ensifer as described by A. Milne-Edwards (1881) from the Lesser Antilles, while H. aff. ensifer from the central Pacific have morphological variations that support a status as a separate species. Careful examinations of additional specimens from both regions and DNA sequencing are, therefore, needed to clarify the status of Pacific H. aff. ensifer .
