Morphostenophanes yunnanus (Zhou, 2020) is widely distributed from central to eastern Yunnan with distinct geographical variations in morphology. Beetles were collected in Manwan Town, and a mitochondrial genome sequence (GenBank accession number MZ298928) of this species was sequenced using the MGI-SEQ 2000 platform, assembled using NOVOPlasty v4.3.1, and characterized. The mitogenome was a circular DNA molecule of 15,690 bp with 64.710% AT content, which comprised 13 protein-coding genes, 22 tRNA genes, two rRNA genes, and one control region. The protein-coding genes showed the typical ATN (Met) and TTG (Met) start codons, except nad1 and cox1 (TTG as start codon), and were terminated by typical TAN stop codons. The maximum-likelihood polygenetic tree was generated using protein sequences of thirteen protein-coding regions of seventeen mitogenomes with mtREV + G + F + I with 1000 replicates under the Bayesian information criterion using MEGA 11, which showed that M. yunnanus was the most closely related to M. sinicus. This study provides essential genetic and molecular data for phylogenetic analyses of the genus Morphostenophanes.
