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.

The larval stages of the riffle beetle Hydora annectens Spangler and Brown are described and
illustrated for the first time. They are compared to Hydora larvae from New Zealand. A key to the
larvae of the New World genera is given. The distribution of known species of Larainae is
synopsized and a checklist of genera and species is given.
