The complete mitochondrial genome (mitogenome) of Monopis longella Walker, 1863 (Lepidoptera: Tineidae) comprises 15,541 bp and contains a typical set of genes and one non-coding region. The gene arrangement of M. longella is unique for Lepidoptera in that it has a trnI-trnM-trnQ sequence in the A + T-rich region and ND2 junction. Unlike most other lepidopteran insects, in which the COI gene has CGA as the start codon, M. longella COI has an ATT codon. Phylogenetic analyses based on the concatenated sequences of 13 protein-coding genes and two rRNA genes, using the Bayesian inference (BI) method, placed M. longella in the Tineidae, sister in position to the cofamilial species, Tineola bisselliella, with the highest nodal support. Tineidae, represented by three species including M. longella, formed a monophyletic group with high support (Bayesian posterior probability = 0.99). Within Tineoidea the sister relationship between Tineidae and Meessiidae was obtained with the highest support, leaving Psychidae occupying the basal lineage of the two families.
