The mitochondrial genome of Xanthochlorus tibetensis (Diptera: Dolichopodidae)

Abstract

The long-legged fly Xanthochlorus tibetensis belongs to the subfamily Xanthochlorinae of Dolichopodidae. The mitogenome of X. tibetensis was sequenced, it is the first representative complete mitogenome from this subfamily. This mitogenome is 15,580 bp in size, includes 13 protein-coding genes, 22 transfer RNAs, and two ribosomal RNAs. All genes have the same location and coding strand as in other published species of Dolichopodidae. Nucleotide composition is biased toward A and T, which together made up 77.6% of the entire genome. Bayesian inference strongly supported the monophyly of Empidoidea, Empididae and Dolichopodidae, with the phylogenetic relationships within Empidoidea: ((Dolichopodinae + Xanthochlorinae) + Neurigoninae) + ((Trichopezinae + (Empidinae + Oreogetoninae)) + Ocydromiinae).
