Monomorium is one of the most species-rich yet taxonomically problematic ant genera. An East Asian species, M. triviale Wheeler, W.M., 1906, reproduces by obligate thelytokous parthenogenesis and performs strict reproductive division of labor. We sequenced the M. triviale mitogenome using next-generation sequencing methods. The circular mitogenome of M. triviale was 16,290 bp in length, consisting of 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNAs, and a single non-coding region of 568 bp. The base composition was AT-biased (82%). Gene order rearrangements were detected and likely to be unique to genus Monomorium. We announce the M. triviale mitogenome as additional genomic resources for phylogenetic characterization of Monomorium and comparative genomics of parthenogenetic ant species.
