| Outline of Final Research Achievements |
Specimens of grasshopper insects of the family Tettigoniidae were collected from various parts of Japan. Male calls are also recorded as much as possible. DNA extraction was performed from each individual, and molecular phylogenetic analysis was performed. As a result of sequencing the partial sequence of mitochondrial COI gene and performing molecular phylogenetic analysis, it became clear that phylogenetic groups that should be treated as some undescribed species are geographically differentiated in the genus Tettigonia. DNA samples were collected for species other than Tettigonia ones, partial sequences of the COI gene were determined, and DNA barcoding was performed.

| Academic Significance and Societal Importance of the Research Achievements |
バッタ目だけでなく昆虫類一般について分子系統学的な解析が急速に進んできているが、キリギリス科のヤブキリ属についても多数の未記載種が存在することが明らかとなった。いままで単一の種として考えられてきた種について分子系統解析を行うと実は複数の種が含まれていることが明らかになることがあるが、今回のケースはそれに該当するものである。解析を行った地域個体群の数が限られており、今後サンプリングする地域を増やすことにより、さらに詳細な分布情報が明らかになると期待される。
