The true bug, Gonopsis affinis, is an important pest in China. Here, we determined the complete mitogenome of G. affinis, which is the first for the subfamily Phyllocephalinae. This 16,011-basepair (bp) mitogenome comprises of 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes, and an A + T-rich region. The gene order and the orientation are similar to those of other sequenced Hemipteran species. All PCGs start with ATN codons, except COI, and end with TAA. The 22 tRNAs have a typical cloverleaf secondary structure except trnS-Ser (AGN), which lacks a dihydrouridine (DHU) arm. Phylogenetic analyses highly supported the monophyly of each family, and confirmed the reasonable placement of G. affinis.
