Most species of Scydmaenus Latreille described by Herbert Franz are impossible to identify without re-examination of the type material. The Chinese fauna is no exception and it is easy to find specimens whose aedeagi resemble those illustrated by Franz, but the only way to identify them is to directly compare new material with types. On the other hand, the aedeagi of type specimens often look slightly or even strongly different from those illustrated in original descriptions, which increases the confusion. Six species of Scydmaenus described by Franz and occurring in continental China are here redescribed, and the aedeagi of holotypes are illustrated in detail: S. chinensis, S. fukiensis, S. kunmingensis, S. sinensis, S. szechuanensis, and S. kiautunensis. The first five species are confirmed to belong in the nominotypical subgenus; S. kiautunensis is transferred from Scydmaenus (s. str.) to the subgenus Nepaloscydmaenus Franz. As previous checklists of Palaearctic or Eastern Asian Scydmaeninae contain incomplete data, an updated and annotated checklist of Scydmaenus species so far recorded from the People's Republic of China, Taiwan and Hong Kong is given, with comments on possible misidentifications, possible synonymies and distributional issues.
弗朗茨描述的大多数 Scydmaenus Latreille 物种如果不重新检查模式标本，就无法识别。中国动物群也不例外，很容易找到与弗朗茨所描绘的类似的外生殖器的标本，但唯一的识别方法是将新材料与模式标本直接进行比较。另一方面，模式标本的外生殖器通常与原始描述中所描绘的略有不同，甚至强烈不同，这增加了混淆。本文重新描述了在中国大陆发现的由弗朗茨描述的 6 种 Scydmaenus 物种，并详细说明了模式标本的外生殖器：中华 Scydmaenus chinensis、福氏 Scydmaenus fukiensis、昆明 Scydmaenus kunmingensis、中华 Scydmaenus sinensis、四川 Scydmaenus szechuanensis 和九台 Scydmaenus kiautunensis。前 5 种被确认为属于指名亚种；九台 Scydmaenus kiautunensis 从 Scydmaenus (s. str.) 转移到尼泊尔 Scydmaenus Franz 亚属。由于之前的古北界或东亚 Scydmaeninae 清单包含不完整的数据，因此给出了截至目前记录在中国、台湾和香港的 Scydmaenus 物种的更新和注释清单，并对可能的误识别、可能的同物异名和分布问题进行了评论。
