Ophiotreta valenciennesi (Lyman, 1878) Material. Sta. CP 1646: 4 spms. Remarks. Currently, two subspecies are recognized within O . valenciennesi , the nominate Indo-Pacific form and the Atlanto-Mediterranean O . valenciennesi rufescens Koehler, 1896. The differences between these are more rugose disk granules and longer adoral shields in the nominate subspecies (Paterson 1985). Mortensen (1933 b) observed a large variability in the oral shields of Atlantic specimens, which he referred to rufescens , because he found them different from typical valenciennesi . This distinction cannot be maintained though, since Pacific specimens fall within the variability of rufescens (O'Hara & Stöhr 2006, and Lifou material). Given the high variability of several characters it is possible that these forms represent a species complex, but a subspecies distinction cannot be maintained. The delimitation of Ophiotreta from Ophiacantha rests mainly on the usually spatulate shape of the distal oral papilla in Ophiotreta (Verrill 1899 b) . This character has however also been shown for Ophiacantha bidentata (Bruzelius, 1805), the type species of Ophiacantha (Martynov & Litvinova 2008). Another generic character, the flat and serrated arm spines, is shared by Ophiopristis , of which Ophiotreta originally was a subgenus (Verrill 1899), and by Ophiocopa , suggesting possible affinities between these genera, which were placed in three different subfamilies (Paterson 1985). This may be additional evidence supporting Martynov's (2010 b) decision to drop the subfamilies. : Published as part of Stöhr, Sabine, 2011, New records and new species of Ophiuroidea (Echinodermata) from Lifou, Loyalty Islands, New Caledonia, pp. 1-50 in Zootaxa 3089 on pages 20-21, DOI: 10.5281/zenodo.279037 : {"references": ["Lyman, T.
