First record of the Heterotoma planicornis (Hemiptera, Heteroptera, Miridae), an introduced species in the Korean Peninsula, with characterization of its complete mitochondrial genome

The West Palearctic genus Heterotoma Lepeletier & Serville, 1825, and its included species H. planicornis (Pallas, 1772) (Hemiptera, Heteroptera, Miridae, Orthotylinae) are reported from the Korean Peninsula. Heterotoma planicornis is diagnosed, and its dorsal habitus and the genitalia of both sexes are illustrated. The possible introduction of this European species into the Korean Peninsula is discussed.

The complete mitochondrial genome of the species is provided. The circular mitogenome of H. planicornis is 16,179 bp long, comprising 13 protein-coding genes, two ribosomal RNA genes, and 22 transfer RNAs, and shows the same gene order as the closely allied species Mecomma ambulans (Fallén, 1807). The A – T content of the total sequence was 71.54 %.

An analysis using a cytochrome oxidase I (COI) neighbor-joining (NJ) tree revealed that the Korean H. planicornis population formed two distinctive groups, with a 1.8 % sequence difference between them.
