The (non) accuracy of mitochondrial genomes for family-level phylogenetics in Erebidae (Lepidoptera)

"The use of molecular data to study the evolutionary history of organisms has revolutionized the field of systematics. Now with the appearance of high throughput sequencing (HTS) technologies, more and more genetic sequence data are available. One of the important sources of genetic data for phylogenetic analyses has been mitochondrial DNA. The limitations of mitochondrial DNA for the study of phylogenetic relationships have been thoroughly explored in the age of single locus phylogenetic studies. Now with the appearance of genomic scale data, increasing number of mitochondrial genomes are available, leading to an increasing number of mitophylogenomic studies. Here, we assemble 47 mitochondrial genomes using whole genome Illumina short reads from representatives of the family Erebidae (Lepidoptera), in order to evaluate the accuracy of mitochondrial genome application in resolving deep phylogenetic relationships. We find that mitogenomes are inadequate for resolving subfamily-level relationships in Erebidae, but given good taxon sampling, we see its potential in resolving lower level phylogenetic relationships."
