New taxonomic and distributional data for five species of the genera Pseudatheta Cameron, 1920 and Phymatura Sahlberg, 1876 from Japan are provided, and the following seven species are recognized: Pseudatheta crenulicauda (Bernhauer, 1907), comb. nov. (= Pseudatheta similis Pace, 2010, syn. nov.); Pseudatheta taiwanensis Pace, 2008; Pseudatheta hilaris (Sharp, 1888), comb. nov.; Pseudatheta cooteri Pace, 1998; Pseudatheta elegans Cameron, 1920; Phymatura japonica Cameron,1933, stat. rev. (= Phymatura cooteri Assing, 2005, syn. nov.); and Phymatura russa Assing, 2021. Pseudatheta cooteri, Ps. elegans, Ps. taiwanensis, and Ph. russa, are recorded from Japan for the first time. Platyola oligotinula (Sharp, 1888), comb. rev. is excluded from Pseudatheta and confirmed as a member of the genus Platyola Mulsant & Rey, 1875. Lectotypes are designated for two species, Atheta crenulicauda (= Ps. crenulicauda comb. nov.) and Homalota oligotinula (= Platyola oligotinula comb. rev.). Although the two genera were reviewed in this paper, there are some diagnostic problems in the two genera and in species classification and identification, and further studies, including DNA analysis, are required in the future. We also examined specimens from outside of Japan relevant to the taxonomic study of Japanese species.
提供了日本五个属 Pseudatheta Cameron, 1920 和 Phymatura Sahlberg, 1876 物种的分类和分布新数据，并确认了以下七个物种：Pseudatheta crenulicauda (Bernhauer, 1907)，组合新种（= Pseudatheta similis Pace, 2010，同物异名）；Pseudatheta taiwanensis Pace, 2008；Pseudatheta hilaris (Sharp, 1888)，组合新种；Pseudatheta cooteri Pace, 1998；Pseudatheta elegans Cameron, 1920；Phymatura japonica Cameron,1933，状态修订（= Phymatura cooteri Assing, 2005，同物异名）；和 Phymatura russa Assing, 2021。Pseudatheta cooteri、Ps. elegans、Ps. taiwanensis 和 Ph. russa 首次在日本被记录。Platyola oligotinula (Sharp, 1888)，组合修订，被排除在 Pseudatheta 之外，并被确认为 Platyola Mulsant & Rey, 1875 的一个成员。为两个物种指定了模式标本，Atheta crenulicauda（= Ps. crenulicauda 组合新种）和 Homalota oligotinula（= Platyola oligotinula 组合修订）。虽然本文对这两个属进行了综述，但这两个属以及物种分类和鉴定存在一些诊断问题，未来还需要进一步的研究，包括 DNA 分析。我们还检查了与日本物种分类研究相关的日本以外的标本。
