Most of the species are distributed in Holarctic, Oriental, and/or Australasian realms while in South America only six species have been recorded, including a single one known from Peru.Two cucujid beetle species, Palaestes abruptus Sharp, 1899 and P. nicaraguae Sharp, 1899, are recorded from South America for the first time. The species are recorded from the Pasco (P. abruptus), and Cusco and Junín (P. nicaraguae) Regions of Peru, based in part o data collected through the iNaturalist citizen science database. Habitats of both species are presented on pictures for the first time. A country-level checklist to Cucujidae species currently known from South America is provided.
