Description of immature stages of Laccobius kunashiricus, with a key to genera of the Laccobiini based on larval characters (Coleoptera: Hydrophilidae).

Immature stages of Laccobius (Laccobius) kunashiricus Shatrovskiy, 1984 are described based on specimens reared from adults collected in the fi eld. The egg-case, all larval instars and pupa are described in detail, including primary and secondary chaetotaxy of the larval head. The biology of the species was observed and is briefl y discussed. We also summarize the knowledge of immature stages of Laccobius Erichson, 1837 and provide a key to identify larvae of the known Laccobiini genera. [ABSTRACT FROM AUTHOR]
