Three new species of the subgenus Distichalius Casey, 1915 of the genus Quedius Stephens, 1829 are described based on specimens collected in China: Q. (Distichalius) biprominulus sp. nov., Yunnan; Q. (Distichalius) fusus sp. nov., Beijing; and Q. (Distichalius) paululus sp. nov., Sichuan. The new species belong to the Quedius elpenor group and increase the number of species of this group to 10. Line drawings and color illustrations of adults and genitalia of the new species are given. A key to all species of this group is provided and their geographical distribution is mapped.
基于在中国采集的标本，描述了1829年斯蒂芬斯（Stephens）属Quedius下的1915年Distichalius Casey亚属的三个新物种：云南的双突Quedius（Distichalius）biprominulus sp. nov.；北京的梭形Quedius（Distichalius）fusus sp. nov.；以及四川的微小Quedius（Distichalius）paululus sp. nov.。这些新物种属于Quedius elpenor组，使该组的物种数量增加到10种。给出了新物种成虫和生殖器的线条图及彩色插图。提供了该组所有物种的检索表，并绘制了它们的地理分布图。
