Complete mitochondrial genome of Heterostomus Sp. (Diptera, Xylophagidae)

Among all species of flies, Xylophagidae is one of the most primitive Brachycera families. We sequenced and annotated the mitochondrial genome of Heterostomus sp., the first representative of subfamily Xylophaginae with complete mitochondrial data. This mitogenome is 15,897 bp totally, which consists of 22 transfer RNAs, 13 protein-coding genes, two ribosomal RNAs and non-coding control regions. All genes have the conservational arrangement like other published species of Brachycera. The nucleotide composition biases toward A and T, the overall A + T% was up to 78.7% of the entire mitogenome. Both Bayesian inference and ML analysis strongly supported the monophyly of Xylophagidae. Our results also suggested that Xylophagomorpha is the sister group to Stratiomyomorpha.
