Podismini族（直翅目：蝗科：黑蝗亚科）的成员主要分布在欧亚大陆和北美的西部和东部地区。本研究的主要目的是通过比较细胞色素c氧化酶亚基I（COI）线粒体基因的部分序列，探讨日本足蝗的系统发育关系。在分析中使用了40种podismine物种（包括19种日本物种）和37种来自其他部落的Melanoplinae（Dacacultini，Dichroplini，Melanoplini和Jivarini）。所有的日本Podismini，除了Anapodisma，被安置在一个支持良好的subdade。然而，我们的研究结果并不符合Tonkinacridina的地位的形态相似性的基础上的分类。这组日本物种与其他米拉梅利纳属和Podismina属的物种构成了一个单一的lade，而欧亚大陆的Tonkinacridina物种则被放置在其他单独的Hades。这种不一致性可能是由于大陆和古岛屿之间的历史迁移事件和随后的趋同/平行进化的形态。根据重建的系统发育，对Podismini和其他部落的系统发育位置也作了一些评论。
Members of the tribe Podismini (Orthoptera: Acrididae: Melanoplinae) are distributed mainly in Eurasia and the western and eastern regions of North America. The primary aim of this study is to explore the phylogenetic relationship of Japanese Podismini grasshoppers by comparing partial sequences of cytochrome c oxidase subunit I (COI) mitochondrial gene. Forty podismine species (including nineteen Japanese species) and thirty-seven species from other tribes of the Melanoplinae (Dactylotini, Dichroplini, Melanoplini, and Jivarini) were used in the analyses. All the Japanese Podismini, except Anapodisma, were placed in a well-supported subdade. However, our results did not correspond with the classification on the basis of morphological similarity for the status of Tonkinacridina. This group of Japanese species constituted a single lade with other species of Miramellina and Podismina, while Eurasian continental species of Tonkinacridina were placed in other separate Hades. This incongruence might have resulted from historical migratory events between continent and ancient islands and subsequent convergent/parallel evolution in morphology. Some remarks on phylogenetic positions in Podismini and other tribes were also made in terms of reconstructed phylogeny.
