038287FEFFCCDF4EFF34F8CAFCE4FF37.taxon	discussion	Remarks. Stenopus pyrsonotus is a shallow-water species common in caves the Marquesas between 20 – 35 m. This species was photographed by the ROV at 129 m, being its deepest record. A specimen of S. pyrsonotus collected in 1997 with a dredge at 85 – 87 m off Hiva Oa (R / V Alis, unpublished record, MUSORSTOM 9, stn DW 1217) confirms the observations made with the ROV.	en	Poupin, Joseph, Corbari, Laure, Pérez, Thierry, Chevaldonné, Pierre (2012): Deep-water decapod crustaceans studied with a remotely operated vehicle (ROV) in the Marquesas Islands, French Polynesia (Crustacea: Decapoda).

Enoplometopus crosnieri was photographed at 50 – 60 m and 204 m which extends significantly its previous depth range of 84 – 120 m (Chan & Ng 2008).	en	Poupin, Joseph, Corbari, Laure, Pérez, Thierry, Chevaldonné, Pierre (2012): Deep-water decapod crustaceans studied with a remotely operated vehicle (ROV) in the Marquesas Islands, French Polynesia (Crustacea: Decapoda).

038287FEFFCFDF4EFF34FDCBFDF6FAE4.taxon	discussion	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. Plesionika edwardsii (Brandt, 1851).

038287FEFFCFDF4FFF34F934FD20F906.taxon	discussion	Remarks. This species is rarely reported. For a long time it was known only from its type locality (Natal, South Africa) but Chan & Yu (1995) and Richer de Forges & Laboute (1995) have indicated that it is widely distributed in the Indo-west Pacific. In French Polynesia it was already reported from the Tuamotu, 250 m (Poupin 1996: 14, pl. 6 f). Puerulus sp. Chan et al. (in press). Stn 36, Eiao, 227 m (Fig. 4 c – d).

A morphological re-examination coupled with DNA sequencing has shown, however, that the Marquesan specimens belong to a new species nested within the Puerulus angulatus complex of species (Chan et al. in press)	en	Poupin, Joseph, Corbari, Laure, Pérez, Thierry, Chevaldonné, Pierre (2012): Deep-water decapod crustaceans studied with a remotely operated vehicle (ROV) in the Marquesas Islands, French Polynesia (Crustacea: Decapoda).

038287FEFFC1DF40FF34FAA9FE2FF98F.taxon	discussion	Remarks. Metadynomene devaneyi is known from the Hawaiian and Marquesas Is (Ng & McLay, 2010). In French Polynesia, a distinct species is reported from the Tuamotu Fangataufa atoll, 310 m, Metadynomene tuamotu Ng & McLay, 2010.	en	Poupin, Joseph, Corbari, Laure, Pérez, Thierry, Chevaldonné, Pierre (2012): Deep-water decapod crustaceans studied with a remotely operated vehicle (ROV) in the Marquesas Islands, French Polynesia (Crustacea: Decapoda).

038287FEFFC0DF42FF34F887FAC3FE87.taxon	discussion	Remarks. Tanaoa serenei (Richer de Forges 1983) was described based on specimens from Tahiti (R / V Tainui, trap, 400 – 500 m), Samoa, and Guam (Richer de Forges 1983: 634). Galil (2003: 402) has synonymised T. serenei with T. distinctus (Rathbun, 1894). Recently, however, Ng & Richer de Forges (2007: 16) concluded that the two species are distinct, with T. distinctus known with certainty only from the Hawaii Is. and T. serenei from French Polynesia, Wallis & Futuna, Samoa, Guam, and questionably from the Solomon Is. (as T. distinctus; in Galil 2007), and New Zealand (as T. distinctus; in Galil 2003 and Yaldwyn & Webber 2011).	en	Poupin, Joseph, Corbari, Laure, Pérez, Thierry, Chevaldonné, Pierre (2012): Deep-water decapod crustaceans studied with a remotely operated vehicle (ROV) in the Marquesas Islands, French Polynesia (Crustacea: Decapoda).

If our identification of Quadrella aff. coronata is confirmed when specimens collected are available for examination, it will represent a significant geographic extension for this species. This coral associated crab is widespread in the Indian Ocean, the Philippines, Papua New Guinea, and Vanuatu, from 2 – 26 m to 189 – 194 m (see Galil 1986; Castro 1999, 2009), and was recently reported at 442 – 491 m off Madagascar (Castro, in press: MIRIKY Expedition, Madagascar, stn CP 3210, 29.6.2009, 12 ° 44 ' S, 48 ° 12 ' E, 442 – 491 m).	en	Poupin, Joseph, Corbari, Laure, Pérez, Thierry, Chevaldonné, Pierre (2012): Deep-water decapod crustaceans studied with a remotely operated vehicle (ROV) in the Marquesas Islands, French Polynesia (Crustacea: Decapoda).
