Apenborn (2013) gave a first overview of the water beetle fauna in the “Área de Conservación Privada Panguana” (ACP), Huánuco Department, listing 122 species in ten families but no Haliplidae . After more than 30 years of water beetle collecting a single specimen of Haliplus crassus Chapin, 1930 ( Fig. 1 View Fig ) was collected in small puddles, near the buildings of the Panguana Research Station, at the edge of primary lowland Amazon rainforest. Most probably, the specimen was a lost single animal, coming from a well vegetated pond or a slow flowing ditch in the open farmland, nearby the reserve. Until now H. crassus was only known from single locations in Panama, Venezuela, Brazil and Paraguay, where it has been collected in clear lowland ponds and lagoons overgrown with aquatic vegetation (Van Vondel & Spangler 2008, Van Vondel 2016). This is the first record of the species for Peru. Altogether four species of Haliplidae are now known from Peru.
