Mitochondrial genomes (mitogenomes) have been widely used for studies on phylogenetic relationships and molecular evolutionary biology. Here, the complete mitogenome sequence of Spilosoma lubricipedum (Noctuoidea: Erebidae: Arctiinae) was determined (total length 15,375 bp) and phylogenetic analyses S. lubricipedum were inferred from available noctuid sequence data. The mitogenome of S. lubricipedum was found to be highly A + T-biased (81.39%) and exhibited negative AT- and GC-skews. All 13 protein-coding genes (PCGs) were initiated by ATN codons, except for cox1 with CGA. All tRNAs exhibited typical clover-leaf secondary structures, except for trnS1. The gene order of the S. lubricipedum mitogenome was trnM-trnI-trnQ-nad2. The A + T-rich region of S. lubricipedum contained several conservative features common to noctuid insects. Phylogenetic analysis within Noctuoidea was carried out based on mitochondrial data. Results showed that S. lubricipedum belonged to Erebidae and the Noctuoidea insects could be divided into five well-supported families (Notodontidae + (Erebidae + (Nolidae + (Euteliidae + Noctuidae)))).
