Characterization of the complete mitochondrial genome of the Yunnan endemic grasshopper Longchuanacris curvifurculus (Insecta: Orthoptera: Catantopidae)

Longchuanacris curvifurculus (L. curvifurculus) was once a dominating grasshopper in the Yunnan province (People's Republic of China) that occupy important ecological niche. However, its population has severely declined because of the deterioration of ecological environment. Identifying the species and source of L. curvifurculus is important for biodiversity conservation and ecological/environmental preservation. In the study, the complete mitochondrial genome of L. curvifurculus was assembled from high-coverage (36.8x) Illumina MiSeq sequencing data. The circular genome is 15,450bp in length, harboring 37 typical mitochondrial genes and one control region. The nucleotide composition is asymmetric (43.0% A, 14.3% C, 10.5% G, and 32.2% T), with an overall A+T content of 75.2%. All the protein-coding genes (PCGs) are initiated with typical ATN start codons and terminated by the typical TAA codons or the incomplete T(aa) codon. The control region has a remarkably high A+T content (84.9%) and is located between genes rrnS and trnV.
