Seven species of the genus Aulodrilus (Annelida, Clitellata, Tubificinae) are studied, based on new material from Japan. Aulodrilus dentosus sp. nov. is characterized as having tubular atrium, forked or bifid distal ends of dorsal crotchets, but no genital chaetae, and A. aestivus sp. nov. is characterized as having crescent-shaped atrium, median male bursa, and bifid chaetae in the dorsal bundles. Five other congeners are redescribed: A. limnobius Bretscher, A. pluriseta (Piguet), A. pigueti Kowalewski, A. japonicus Yamaguchi, and A. americanus Brinkhurst Cook. Comparison of taxonomic characters among the 14 species recognized in the genus to date shows that three species differ from other congeners in several features: A. paucichaeta Brinkhurst Barbour, A. adetus (du Bois-Reymond Marcus), and A. apeniatus Cui Wang. They are provisionally maintained in the genus.
基于来自日本的新材料，对 7 种 Aulodrilus 属（环节动物门，寡毛目，颤蚓科）进行了研究。新种 Aulodrilus dentosus 的特征为具有管状的鳃腔，背叉刚毛的末端分叉或二分叉，但没有生殖刚毛；新种 A. aestivus 的特征为具有新月形的鳃腔、中间的雄性精荚囊和背束的二分叉刚毛。其他 5 个近缘种被重新描述：A. limnobius Bretscher、A. pluriseta (Piguet)、A. pigueti Kowalewski、A. japonicus Yamaguchi 和 A. americanus Brinkhurst Cook。对迄今为止在该属中确认的 14 个种的分类特征进行比较表明，有 3 个种在几个特征上与其他近缘种不同：A. paucichaeta Brinkhurst Barbour、A. adetus (du Bois-Reymond Marcus) 和 A. apeniatus Cui Wang。它们被暂时归入该属。
