The hexapodid genera Hexapus De Haan, 1833, Hexapinus Manning & Holthuis, 1981, Latohexapus Huang, Hsueh & Ng, 2002, and Hexaplax Doflein, 1904, are revised and redescribed on the basis of their respective type species. Hexapus s. str. is redefined and a new species is described from Indonesia. Hexapinus is restricted for H. latipes (De Haan, 1835), H. edwardsi (Serène & Soh, 1976) and three new species from Indonesia, Philippines, China and Japan. A new genus, Mariaplax, is established for Lambdophallus anfractus Rathbun, 1909, Hexapus granuliferus Campbell & Stephenson, 1970, and 11 new species from the China, Japan, Vietnam, Philippines, Indonesia, Singapore, New Guinea and Australia. A new genus, Rayapinus, is recognised for an unusual new species from Japan. Two new species of Hexaplax from Papua New Guinea, Philippines, Taiwan, and Japan are described. A new genus, Theoxapus, is also established for the east Atlantic Hexapus buchanani Monod, 1956, which had previously been placed in Hexapinus. A revised key to the genera of Hexapodidae is presented.
