Hypomecis punctinalis Scopoli, 1763 belongs to the Lepidopteran family Geometridae. We sequenced the complete mitochondrial genome (mitogenome) of H. punctinalis. The mitogenome is 15,648 bp long and contains a typical set of genes (13 protein-coding genes (PCGs), 22 tRNA genes, and two rRNA genes) and a 484 bp AT-rich region. All PCGs start with ATN codons and stop at TAA codon except for cox1 using CGA as initiation codon and nad4 and nad5 using incomplete termination codon T. Within the mitogenome, 17 intergenic spacers and seven overlaps are founded. The intergenic nucleotides are 294 bp in total and two longest intervals locate between trnGln and nad2 as well as trnCys and trnTyr. The overlap nucleotides are 47 bp in total and the maximum overlap lies between cox2 and trnLys. The AT-rich region of the mitogenome contains an ‘ATAGA + polyT’ motif, three copies of 30-bp-repeat and a short polyA tail. The phylogenetic tree shows the relationships of four subfamilies of Geometridae are (((Ennominae + Geometrinae)+Larentiinae)+Sterrhinae)) and the relationships within subfamily Ennominae are ((((Erannis+Biston)+(Jankowskia+(Hypomecis+(Apocheima+Milionia))))+Ectropis)+Abraxas)+Phthonandria)+Celenna).
