The genus Nipponodrasterius Kishii, 1966 was established as a member of the subfamily Conoderinae Fleutiaux, 1919 (now tribe Oophorini Gistel, 1848; subfamily Agrypninae Candèze, 1857) based on N. alpicola. The genus was suggested to be unlikely to belong to Agrypninae because it lacks diagnostic features of the Agrypninae. However, there are no taxonomic treatments for the genus or species. Here, we review the status of the genus and species by examining the holotype of N. alpicola. Consequently, the genus was found to be a junior synonym of the genus Gamepenthes Fleutiaux, 1928 and N. alpicola was found to be a junior synonym of G. pictipennis (Lewis, 1894). We review all species of Gamepenthes in Japan and provide a key to species.

Nipponodrasterius Kishii属（鞘翅目，Elateridae，Agrypninae），Gamepenthes Fleutiaux属的初级同义词（鞘翅目，Elateridae，Elaterinae），并回顾了日本Gamepenthes物种

Nipponodrasterius Kishii属，成立于1966年，是基于alpicola猪笼草的Conoderinae Fleutiaux家族（1919年，现在是Oophorini Gistel部落，1848年； AgrypninaeCandèze家族）的成员。由于该属缺乏Agrypninae的诊断特征，因此建议该属不太可能属于Agrypninae。但是，没有针对属或物种的分类学治疗方法。在这里，我们通过检查N. alpicola的全型来回顾属和种的状态。因此，该属被认为是Gamepenthes Fleutiaux属（1928）的初级同义词，而N. alpicola被发现是G. pictipennis（Lewis，1894）的初级同义词。我们回顾了日本的所有Gamepenthes物种，并提供了物种的关键。
