They are distributed in Africa ( DR Congo, Madagascar, South Africa, Tanzania); Asia ( China (Fujian, Yunnan), Christmas Is., Indonesia (Sumatra), Japan (Honshű, Iriomote Is., Ishigaki Is., Okinawa Is., Tokunoshima Is., Tsushima Is., Yona- guni Is.), Malaysia (Pahang, Pahang / Selangor, Sarawak), Nepal, Philippines (Leyte, Luzon, Palawan), Sri Lanka, Taiwan, Thailand), Australia-Pacific ( Australia, Fiji, Lord Howe Is., New Caledonia, Papua New Guinea, Samoa); Indian Ocean (Grand Comore Is., Mauritius, Reunion Is., Seychelles); extinct species were reported from the Eo- cene of Ukraine.

Cephennomicrus can be distinguished from all other Cephenniini by the antennae with a symmetrical dimerous or trimerous club; the pronotum with two pairs of antebasal pits (in some species one pair reduced or additionally a transverse groove occurs); the prothorax lacking glandular openings and internal 'cavities'; the prosternal process in ventral view subtriangular, also subtriangular in cross section, in lateral view only slightly bent caudad, with its apex directed posteroventrad, not extending ventrally beyond ventral margins of procoxae; and the mesoventral intercoxal process broad and nearly flat.
