Characterization of the complete mitochondrial genome of the firefly, Luciola substriata (Coleoptera: Lampyridae)

Abstract

The firefly, Luciola substriata (Coleoptera: Lampyridae), is an aquatic firefly species, whose larvae inhabit ponds or lakes. Here we present the complete mitochondrial (mt) genome of the firefly (GenBank accession number KP313820) and provide its annotation. This circular genome is 16,248 bp in length and contains 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and a non-coding AT-rich region. Similar to other firefly species, the base composition of this mitochondrial genome is also biased toward A and T (44.09% A, 34.00% T, 12.89% C, and 9.01% G). All 13 protein-coding genes start with a typical mitochondrial start codon, and terminate with a usual stop codon TAA, or TAG or a single T. The non-coding AT-rich region (1636 bp in length) include one (A)₂₀, and two (T)₁₅ tandem repeats, and one (AAT)₅ element. This mitochondrial genome sequence will promote a better understanding for firefly evolution in the future.
