The grasshopper, Catantops pinguis Stål (Orthoptera: Catantopidae), is a worldwide pest in agriculture. We have obtained the whole mitochondrial genome of C. pinguis (GenBank accession No. MH671309). The entire mt genome is 15,604 bp long with an A + T content of 73.58%. This grasshopper mt genome encodes all the 37 genes that are typically found in animal mt genomes, consists of 13 protein-coding genes, 2 ribosomal RNA, and 22 transfer RNA genes. The gene order is consistent with other sequenced mt genome of grasshoppers. The A + T-rich region of this genome is 754 bp long with the A + T content of 87.27%, and located between the rrnS and trnI genes. Phylogenetic analysis was performed using 13 protein-coding genes with 11 grasshoppers of the family Catantopidae and it was seen that C. pinguis is closely related to Xenocatantops brachycerus.
