Cottony ash psyllid (CAP, Phyllopsis discrepans) is an important, invasive insect pest of ash trees in North America where it has established populations and is the host of a newly identified strain of 'Candidatus Liberibacter solanacearum'. However, not much is known about the diversity of its introduced population. In this study, a CAP mitochondrial genome (mitogenome) sequence was obtained from a collection in Saskatoon, Saskatchewan, Canada. The CAP mitogenome is a circular DNA of 18,824 bp, encoding 13 protein-coding genes, 21 transfer RNA genes, and 2 ribosomal RNA genes. BLAST search using the CAP mitogenome as query against GenBank sequence database showed the mitogenome of Euphyllura phillyreae (15,202 bp) was the most similar (Query Coverage = 77%; Percentage Identity = 78.90%). The CAP mitogenome is significantly different from other known psyllid mitogenomes with the presence of a 4,357 bp control region (CR). The mitogenome sequence will further genomic understand of CAP.
