The taxon relationshops based on Nei's genetic identity and genetic distance were consistent with results obtained from karyotypic analyses.

Nei的遗传距离和遗传一致度进行的聚类分析基本符合传统形态学、细胞学等研究结果：即同属于斑腿蝗科的中华稻蝗和长翅素木蝗遗传距离最小( D = 0.559)，遗传一致度最高( I =0.576)。

Each account describes the taxon's distribution in South Korea in general terms, the overall structure of the forms (which is considered a useful though rather variable feature, Ujihara in lit., pers obs), and then concentrates on the appearance of juvenile/first winter and winter adult plumages.
