Morphological characteristics primarily revealed species described as the sicklefin chimaera, <em>Neoharriotta pinnata </em>(Rhinochimaeridae), longspine chimaera, <em>Chimaera </em>aff. <em>macrospina </em>(Chimaeridae) and Philippine chimaera, <em>Hydrolagus </em>cf. <em>deani</em> (Chimaeridae). The presence of <em>N. pinnata </em>in the Andaman Sea of Thailand provided a plausible extension of its distributional range, but the record of the other two ghost sharks were far outside their known ranges and remained tentative. Using DNA barcoding, the <em>Chimaera </em>aff. <em>macrospina </em>sample was different from Australian <em>C. macrospina</em> and any other <em>Chimaera</em> species whose DNA sequences were available in databases. The sample of <em>Hydrolagus </em>cf. <em>deani </em>showed slight differences in morphology with the known <em>H. deani, H. mitsukurii</em> and <em>H. africanus. </em>It was close to <em>H. africanus</em> based on the genetic information, but state morphologically, especially shape of second dorsal fin, this specimen was most similar to <em>H. deani.</em></p> ER -
