Complete mitochondrial genome of the non-biting midge Polypedilum henicurum Wang, 1995 (Diptera: Chironomidae)

Abstract

The complete mitochondrial genome of Polypedilum henicurum was sequenced and analyzed. The whole mitogenome is 15,964 bp in length and contains 13 protein-coding genes (PCGs), 22 transfer RNAs (tRNAs), and two ribosomal RNAs (rRNAs). The overall nucleotide composition is 39.5% A, 39.0% T, 13.1% C, and 8.4% G. Most PCGs start with ATN codon excluding COX1 (TTG) and all PCGs end with TAA codon. Gene arrangement stays the same with the ancestral mitochondrial genome. Bayesian inference phylogenetic tree supports its close relationship with P. unifascium. This work enriches the library of Chironomidae mitochondrial genomes and provides a valuable resource for understanding the evolutionary history of Polypedilum.
