The mitochondrial genome of Prosthiochaeta sp. (Diptera: Platystomatidae)

Abstract

The mitochondrial genome of Prosthiochaeta sp. was sequenced and annotated as a new representative of family Platystomatidae. The nearly complete mitochondrial genome of Prosthiochaeta sp. is 16,169 bp totally, consisting of 13 protein-coding genes, 2 rRNAs, and 22 transfer RNAs, which gene frame is similar with other dipteran mitogenomes. The nucleotide composition biases toward A and T is 70.8% of the entirety. IQ-tree analysis revealed that Tephritoidea including Prosthiochaeta sp. was monophyletic as a sister group to Opomyzoidea and Syrphoidea. Tephritoidea as well as Syrphoidea and Opomyzoidea were nested in Ephydroidea, while Lauxanioidea and Sciomyzoidea were assigned to be sister groups. Platypezoidea was monophyletic as a basal clade of phylogenetic tree.
