This species is a complex of several distinct genotypes, the most common of which are known as the Tea shot hole borer, Polyphagous shot hole borer, and the Kuroshio shot hole borer ( Stouthamer et al. 2017). The different lineages are supported by rapidly evolving mitochondrial genes and more conserved nuclear gene regions. Although these potential different species display morphological differences, reliable morphological diagnosis has not been established ( Chen et al. 2016).
