根据俄罗斯远东地区的材料，描述了Khasanensis Ameletus sp. nov.，并对Ameletus longulus Sinichenkova，1981进行了重新验证和描述。这两个物种的阴茎结构与Ameletus costalis（Matsumura 1931）相似，本文还提供了描述和绘图。A. khasanensis sp. nov.与A.由于前胫骨背面没有小刺，因此称为肋。A. longulus与A. khasanensis sp. nov.和A.前翅的颜色。A. khasanensissp. nov.肋在右下颌骨上的齿状突的长度，在没有在前股骨基部的背表面上的刚毛组和鳃的宽/长比VII。A. longulus与A. khasanensis和A.上颌骨第一梳状刚毛的齿状突的形状和数目以及股骨前基部背面刚毛的数目与肋的形状和数目有关。
Ameletus khasanensis sp. nov. is described and Ameletus longulus Sinichenkova, 1981 is revalidated and redescribed based on material from the Russian Far East. The structure of the penis of both species is similar to that of Ameletus costalis (Matsumura 1931), a description and drawings of which are also presented in this paper. The male imago of A. khasanensis sp. nov. can be distinguished from that of A. costalis by the absence of spinules on the dorsal surface of the fore tibia. The male imago of A. longulus can be distinguished from A. khasanensis sp. nov. and A. costalis by the color of the forewings. The larvae of A. khasanensis sp. nov. differ from A. costalis in the length of the denticles on the right mandible, in the absence of the group of setae on the dorsal surface at the base of fore femora and the width/length ratio of gill VII. The larvae of A. longulus differ from A. khasanensis and A. costalis in the form and number of the denticles of the first comb-shaped seta of the maxilla and the number of setae on the dorsal surface of the base of the fore femora.
