In this study, we examine the mitochondrial cytochrome oxidase subunit I (MtCOI) nucleotide sequence of <em>S. aurantiacus </em>in order to determine whether it represents a new harpactorine species. A sample from Pancasari, Bali, Indonesia was collected at the same location <em>S. aurantiacus </em>was first discovered in 2007<em>. </em>The selected mtCOI gene (650 bp) was successfully amplified using mtCOI primer pairs LCO1490 and HCO2198, and the resulting MtCOI sequence of the <em>S. aurantiacus</em> sample was compared with those from other hapactorine species recorded in GenBank. This comparison revealed low genetic similarity between <em>S. aurantiacus</em> and most other harpactorine species worldwide, except for the Genus <em>Sycanus </em>(JQ888697) from USA whose mtCOI shares approximately 91% similarity with the Pancasari sample. Phylogenetic analysis indicated a close genetic relationship between <em>Sycanus </em>from Bali and the Genus <em>Sycanus </em>(JQ888697) from the USA. The mtCOI sequence of <em>S. aurantiacus</em> had not been recorded previously, and our comparison with existing Sycanus sequences provides support to the understanding that <em>S. aurantiacus</em> is indeed its own species.</p> ER -
