Clarifying phylogenetic position and reconstructing robust phylogeny of groups using various evidences are an eternal theme for taxonomy and systematics. In this study, the complete mitogenomes of
Longzhouacris mirabilis,
Ranacris albicornis, and
Conophyma zhaosuensis were sequenced using next-generation sequencing (NGS), and the characteristics of the mitogenomes are presented briefly. The mitogenomes of the three species are all circular molecules with total lengths of 16,164 bp, 15,720 bp, and 16,190 bp, respectively. The gene structures and orders, as well as the characteristics of the mitogenomes, are similar to those of other published mitogenomes in Caelifera. The phylogeny of the main subfamilies of Acrididae with prosternal process was reconstructed using a selected dataset of mitogenome sequences under maximum likelihood (ML) and Bayesian inference (BI) frameworks. The results showed that the genus
Emeiacris consistently fell into the subfamily Melanoplinae rather than Oxyinae, and the genus
Choroedocus had the closest relationship with
Shirackiacris of the subfamily Eyprepocnemidinae in both phylogenetic trees deduced from mitogenome protein coding genes (PCGs). This finding is entirely consistent with the morphological characters, which indicate that
Emeiacris belongs to Melanoplinae and
Choroedocus belongs to Eyprepocnemidinae. In addition, the genera
Conophymacris and
Xiangelilacris, as well as
Ranacris and
Menglacris, are two pairs of the closest relatives, but their phylogenetic positions need further study to clarify.
