Abstract:
Kennelia is a small genus in Tortricidae that is distributed in the Oriental and Palaearctic regions, and its taxonomic position within the subfamily Olethreutinae is controversial. For a comprehensive understanding of the genus, we sequenced the mitogenome of Kennelia xylinana, the type species of Kennelia, and Ancylis unculana, a species of Enarmoniini; analyzed the mitogenome characteristics of K. xylinana; and explored its phylogenetic position. Similar to other members of Lepidoptera, the mitogenome of K. xylinana is 15,762-bp long and consists of 13 protein-coding genes (PCGs), two ribosomal RNA genes, 22 transfer RNA genes, and a noncoding control region. In particular, we found a structure (TATAATTAATAA)11 in the middle of the AT-rich region. Based on the Bayesian inference and maximum likelihood analyses of the 13 PCGs of 40 tortricid species, representing 8 tribes of 2 subfamilies, K. xylinana was clustered with two members of Enarmoniini, A. unculana and Loboschiza koenigiana, and formed highly supported monophyly. The results indicate that Kennelia should be placed in the tribe Enarmoniini.
