A new species of Takedactylus Naruse & Maenosono, 2012, and a new genus and species of Aphanodactylidae are described from Japan. Takedactylus compressus n. sp. is collected from Ogasawara Islands. This new species is distinct from the only congener, Takedactylus masatsunei, by the shapes of the carapace, third maxilliped and the ambulatory legs. Another new species, monotypic Lichtylus kaisha n. gen., n. sp., is distinct from all other aphanodactylid species, in generic level, in the shape and position of the palp of third maxilliped, relatively long and slender ambulatory legs, and a combination of other important characters, i.e. the contour of the carapace, the degree of gap between third maxillipeds, condition of the distoflexor corners of second to fifth ambulatory propodi, and relative length of ambulatory dactyli. The present study brings the number of aphanodactylid taxa to 7 genera and 15 species.
