Siamcyclops isanus sp. nov. has been found from a cave in northeastern Thailand. It differs from the other member of its genus by having: 1) smooth free margin of anal operculum, 2) a different armature on the second endopod of the first and fourth legs, 3) the armature of the second endopod of the male third leg, and 4) the shape of spermatophore. The discovery of the second species from the genus Siamcyclops thus leads to the proposal for the generic diagnosis. The morphological differences between the genus Siamcyclops and other closely related genera is added.
