Tettigonia ussuriana and T. dolichopoda maritima differ in the length of tegmina, details in venation, and in females in details of the subgenital plate. The two species of the genus Tettigonia have the same number and morphology of autosomes but a different morphology of the X chromosome: in T. ussuriana it is metacentric, whereas in T. dolichopoda maritima acrocentric. In both species, euchromatic zones and breaks of one or to chromatids during meiosis and mitosis in the X chromosome were observed. Additionally, B chromosomes were noted in most individuals of both species.
乌苏里螽斯和滨海长跗螽斯在翅的长度、翅脉细节以及雌虫亚生殖板细节上存在差异。螽斯属的这两个物种常染色体的数量和形态相同,但X染色体形态不同:在乌苏里螽斯中它是中着丝粒的,而在滨海长跗螽斯中是近端着丝粒的。在这两个物种中,都观察到了X染色体在减数分裂和有丝分裂过程中常染色质区以及一条或两条染色单体的断裂。此外,在这两个物种的大多数个体中都发现了B染色体。
