%X The complete sequence of the mitochondrial gene encoding NADH dehydrogenase subunit 1 (ND1) from a megascolecid earthworm, Amynthas gracilis (Kinberg, 1867), is published in this study. The gene is 923 bp in size, encoding a polypeptide of 307 amino acid residues. Its nucleotide sequence and amino acid sequence are 71.8% and 77.7% identical to those of the European earthworm Lumbricus terrestris ND1 gene, respectively. In addition, the GC contents among some published annelid ND1 full sequences were compared, and the relationships among these sequences were reconstructed using a phylogenetic analysis. Accordingly, we believe that a 3000-bp sequence comprising the ND1 and the CO1 genes and the genes used by Jamieson et al. (2002) can be a good candidate to be used in the phylogenetic analysis to unravel the phylogeny of the Megascolecidae.
