Abstract	The family Cephidae is a relatively modest phytophagous lineage within the suborder Symphyta of the order Hymenoptera. Members of this exclusively endophytophagous lineage feed on graminoids, berry canes, shrubs, and arboreal species. In this study, the nearly complete mitogenome of Trachelus stipa (Hymenoptera: Cephidae) was assembled and annotated as a third-party annotation and compared with the mitogenome of T. iudaicus and T. tabidus. The obtained length of the partial mitogenome of T. stipa was 16,085 bp with an A+T content of 79.02%. The mitogenome was containing 13 protein-coding, two rRNA, 22 tRNA genes and all of the protein coding genes (PCGs) are initiated with ATN as start codon, and all are ended with TAA or T− stop codon. All tRNA genes folded into the usual clover-leaf structure except for tRNA-Ser1. Compared with the inferred insect ancestral mitogenome, the gene orders are mostly conserved, except for the translocation of tRNA-Met and swapped positions of tRNA-Ile and tRNA-Gln. Phylogenetic analysis confirmed the position of T. stipa within genus Trachelus and recovered a relationship of Stenocephus + (Janus + ((Phylloecus + Pachycephus) + (Syrista + (Calameuta + (Trachelus + Cephus)))) in Cephidae.
