Abstract

The complete mitogenome of Smaragdina nigrifrons (GenBank accession number MN584924) is 15,903 bp in length, and includes 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), 2 ribosomal RNA genes, and a control region. The overall base composition was as follows: A, 38.18%; T, 35.25%; C, 15.97%; and G, 10.60%, with a total of A + T content of 73.43%. Eleven reading frame overlaps and thirteen intergenic regions were found in the mitogenome of S. nigrifrons. All 13 PCGs are initiated with the typical ATN codons, and are terminated with either the complete TAA/TAG codons or a single T residue. All tRNAs possess the typical cloverleaf secondary structures except for trnS₁ (AGN). Phylogenetic analyses showed that S. nigrifrons was closely related to Cucujus clavipes, which was consistent with the conventional taxonomy.
