Three species of coelotine spiders of the genera Coelotes and Tegecoelotes from Kyushu District, Japan, are reviewed. Two new species of the genus Coelotes are described under the names, Coelotes bifurcatus n. sp. and C. hiradoensis n. sp. The former new species is distributed in Nagasaki, Saga and Fukuoka Prefectures, northern Kyushu, and is characteristic in having the bifurcate apophysis of male palp. The latter new species is recorded only from Hirado Island in Nagasaki Prefecture and characteristic with the palpal conductor extending in the direction of the tip of cymbium in males and long and slender epigynal teeth in females. Tegecoelotes muscicapus (Bösenberg & Strand 1906) described using a male holotype, and Tegecoelotes ignotus (Bösenberg & Strand 1906) described with two female syntypes are considered to be synonymous, and the former is regarded as a junior synonym of the latter. Tegecoelotes ignotus is recorded for the first time since the original description in 1906. The intraspecific variation recognized in epigynum of this species is reported.
