| Abstract | The first reliable record of Dasyscopelus brachygnathos (Bleeker, 1856) distributed in the Andaman Sea of the Indian Ocean is proved based on the three specimens (62.364.6 mm standard length) caught from R/V Dr. Fridtjof Nansen trawling cruise survey on 8th September 1980, off the coast of the Andaman Sea, Phuket, Thailand, 300400 m depth. This species is different from other congeners by their combination of the following characters: body depth 2227% of standard length; eye diameter 4050% of head length; gill rakers on first arch 79 + 1821; dorsal margin on operculum smooth; body scales markedlyctenoid; scales over anal organ (AO) photophores without elongate spines; postero-lateral organ (Pol) located before a vertical from origin of base of adipose fin; first supraanal organ (SAO1) situated slightly anterior to fourth ventral organ (VO4); a line through SAO1 and second supraanal organ (SAO2) passing variously through or between second ventral organ (VO2) and third ventral organ (VO3); AO 69 + 36 = 1013. |
