Three new species of the caddisfly genus Psilotreta (Trichoptera: Odontoceridae) from Japan are described: P. voluta sp. nov., P. moritai sp. nov., and P. flavida sp. nov. These three species are easily distinguishable by the male genitalia from previously known Japanese species, P. japonica (Banks 1906) and P. kisoensis Iwata 1928. The three new species are similar to P. vertebrata Yuan et al. 2008, P. cuboides Yuan et al. 2008, and P. excavata Yuan et al. 2008 from the Chinese mainland, and P. clyssan Malicky 2014 from Taiwan, in the shapes of the lateral processes and intermediate appendages of segment X of the male genitalia, but can be distinguished from these species and each other. All Japanese species of Psilotreta listed above belong to the P. chinensis Species Group.
三种来自日本的石蚕科 Psilotreta 属新种（鳞翅目：齿石蚕科）被描述：P. voluta sp. nov.、P. moritai sp. nov. 和 P. flavida sp. nov.。这三个种在雄性生殖器上很容易与以前已知的日本种 P. japonica（班克斯 1906）和 P. kisoensis Iwata 1928 区分开来。这三个新种与中国大陆的 P. vertebrata Yuan et al. 2008、P. cuboides Yuan et al. 2008 和 P. excavata Yuan et al. 2008 以及来自台湾的 P. clyssan Malicky 2014 相似，在雄性生殖器第十节的侧突和中间附肢的形状上，但可以与这些种和彼此区分开来。上述日本的所有 Psilotreta 种都属于 P. chinensis 种组。
