Japanese species of the genus Zaitzevia are revised taxonomically. Nine species including one new species, Zaitzevia wakayamana sp. nov. from Honshu (Wakayama Pref.) are recognized in Japanese fauna. All the species are described or redescribed with figures of habitus, elytra, elytral epipleura and male genitalia. Endophallic structures of seven species are described. A key to Japanese species is also given.

Podonychus gyobu sp. nov., a second species of the genus Podonychus J\äch \& Kodada, 1997, hitherto known only from Indonesia, is described from Kyushu, Japan. This new species is similar to P. sagittarius\ J\äch \& Kodada, 1997, but differs from it in the straight penis, arcuate 2nd labial palpomere, and in the 3rd antennomere being longer than wide. The endophallic structures and the larva of P. gyobu sp. nov. are described. A character matrix of the Macronychini genera and a key to the Japanese genera are provided.
