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