Abstract
The coloured righteye flounder, Poecilopsetta colorata Gunther, 1880 was previously known from the eastern Indian Ocean to the South China Sea and Indonesia. Here, a new record from the western Indian Ocean is reported. The new record is based on a specimen collected on the Sakalaves seamounts at 375 m in depth in the Mozambique Channel during a recent oceanographic survey. Four other teleost fish species including an uncommon ophidiid species, Neobythites somaliaensis Nielsen, 1995 were also collected on the same seamounts. The presence of P. colorata in the Mozambique Channel suggests a broad and Indo-West Pacific wide distribution for this relatively rare deep-sea species. The sequence of the cytochrome oxidase subunit-I for the collected specimen is provided as a genetic reference for further DNA barcoding and systematic studies.
Highlights
The coloured righteye flounder, Poecilopsetta colorata Günther, 1880 was previously known from the eastern Indian Ocean to the South China Sea and Indonesia
Seven species of Poecliopsetta occur in the Indian Ocean (P. albomaculata Norman, 1939, P. colorata Günther, 1880, P. natalensis Norman, 1931, P. macrocophala Hoshino, Amaoka and Last, 2001, P. normani Foroshchuk & Fedorov, 1992, P. praelonga Alcock, 1894, P. vaynei Quéro et al, 1988, and P. zanzibarensis Norman, 1939) (Quéro et al, 1988; Hoshino, 2000; Guibord and Chapleau, 2001, 2002; Hoshino et al, 2001; Evseenko, 2004; Kawai and Amaoka, 2006; Kawai et al, 2010)
The authors examined 55 fish specimens collected during the 32-day multi-disciplinary cruise in 2014 of the Research vessel (R/V) Atalante deployed by the French Oceanographic Fleet in the Mozambique Channel in the western Indian Ocean
Summary
The coloured righteye flounder, Poecilopsetta colorata Günther, 1880 was previously known from the eastern Indian Ocean to the South China Sea and Indonesia. Seven species of Poecliopsetta occur in the Indian Ocean (P. albomaculata Norman, 1939, P. colorata Günther, 1880, P. natalensis Norman, 1931, P. macrocophala Hoshino, Amaoka and Last, 2001, P. normani Foroshchuk & Fedorov, 1992, P. praelonga Alcock, 1894, P. vaynei Quéro et al, 1988, and P. zanzibarensis Norman, 1939) (Quéro et al, 1988; Hoshino, 2000; Guibord and Chapleau, 2001, 2002; Hoshino et al, 2001; Evseenko, 2004; Kawai and Amaoka, 2006; Kawai et al, 2010). Only three species (P. natalensis, P. vaynei, and P. zanzibarensis) have been recorded from the Mozambique Channel in. The authors examined 55 fish specimens collected during the 32-day multi-disciplinary cruise (campaign: PAMELA-MOZ01) in 2014 of the R/V Atalante deployed by the French Oceanographic Fleet in the Mozambique Channel in the western Indian Ocean. The purpose of the present work is to record this species in the ichthyofauna of the Mozambique Channel and provide a molecular sequence from a mitochondrial gene as the genetic reference for further DNA barcoding and systematic studies.
