The mitochondrial genome of sp. (Diptera: Empididae).

The dance fly sp. belongs to the subfamily Hemerodromiinae of Empididae. The mitogenome (GenBank accession number: MT396991) of sp. was sequenced, the first representative of the mitogenome of the subfamily. The nearly complete mitogenome is 14,976 bp totally, consisting of 13 protein-coding genes, 2 rRNAs, and 22 transfer RNAs. All genes have the similar locations and strands compared with that of other published species of Empididae. The nucleotide composition biases toward A and T, which together made up 77.2％of the entirety. Bayesian inference analysis strongly supported the monophyly of Empidoidea, Empididae and Dolichopodidae. The phylogenetic relationship within Empidoidea is as follows: (Dolichopodinae + Neurigoninae) + (((Empidinae + Hemerodromiinae) + (Trichopezinae + Oreogetoninae)) + Ocydromiinae) in this study.
