Abstract
Taiwanese species of the genus Laccobius Erichson, 1837 (Coleoptera: Hydrophilidae) are reviewed based on newly collected material and published records. Five species classified in two subgenera are recorded for the region, including L. (Glyptolaccobius) politus Gentili, 1979, L. (Microlaccobius) formosus Gentili, 1979, L. (M.) hammondi Gentili, 1984, L. (M.) roseiceps Régimbart, 1903 and a new species from central and southern Taiwan: L. (M.) hoi. sp.nov. Laccobius philipinus Gentili, 2005 is excluded from Taiwanese fauna. We failed to re-collect Laccobius fragilis Nakane, 1966 despite sampling the area from which it was recorded, and its occurrence in Taiwan hence needs re-confirmation. Distribution data of all Taiwanese species is summarized, and a key of Taiwanese Laccobius and photographs of all species are provided.
