We determined from behavioral and ecological observations that there are two subspecies in Schizotetranychus miscanthi Saito which distributes in Japan. Next, we examined morphological characters of two spider mites species, in order to determine characters reflecting mite body size regardless of mounting methods. Several body characteristics of flattened and non-flattened specimens of Schizotetranychus longus Saito and S.miscanthi Saito were investigated. There are several characters which are not influenced by mounting conditions regardless of sex and species, and which reflect well body length and width.We conducted studies on the phylogeny of Teteranychini by the use of traditional morphological and DNA based methods. The analyses of DNA variation mainly on the genus, Schizotetranychus suggested that there is a consistency between genera categorized by morphological observations and those detected by DNA based method. However, there appears to be a discrepancy between the phylogenic tree expected from morphological data and that by DNA variation. Thus we should conduct more detailed study on them in the future.

通过行为学和生态学观察，确定分布于日本的米氏裂爪螨有两个亚种。接下来，我们研究了两种叶螨的形态特征，以确定反映螨体大小的特征，无论安装方法如何。对长裂爪螨和米氏裂爪螨扁平标本和非扁平标本的若干身体特征进行了研究。利用传统的形态学方法和DNA技术对Teteranychini的生殖发育进行了研究。对裂爪螨属的DNA变异分析表明，形态学鉴定的属与DNA鉴定的属具有一致性。然而，从形态学数据和DNA变异预期的遗传树之间似乎存在差异。因此，我们将来应该对它们进行更详细的研究。
