During the research, 561 individuals represented by 35 species of minute brown scavenger beetles (Coleoptera: Latridiidae) were recorded in the area of Kozienicka Forest and the vicinities of Radom (Central Poland). Both in the area of the Kozienice Forest, as well as in the administrative borders of the city of Radom, 25 species of Latridiidae were found in total. The number of species shared in both areas was 15. Of all Latridiidae identified, 15 species were not previously reported from the Mazowiecka Lowland, and 13 from the Małopolska Upland. The most rare species in Poland were: Corticaria alleni, Corticarina lambiana, Dienerella clathrata, Melanophthalma maura , M. rispini and M. suturalis.
Melanophthalma rispini RÜCKER et JOHNSON, 2007 is recorded for the first time from Poland, based on a male specimen collected in the Sieraków Landscape Park, Wielkopolsko-Kujawska Lowland.
Corticaria interstitialis MANNERHEIM, 1844 (Coleoptera, Latridiidae), collected in Puszcza Białowieska (Białowieża Primeval Forest), is new to the Polish fauna.
Philonthus coprophilus Jarrige, from Pobrzeże Bałtyku Sepedophilus lokayi (Smetana) from Nizina Wielkopolsko-Kujawska (Staphylinidae), Pocadius adustus Reitter (Nitidulidae) from Roztocze and Enicmus atriceps Hansen (Latridiidae) from Beskid Zachodni are new to the Polish fauna. Gabrius bescidicus Smetana (Staphylinidae), Neuraphes ruthenus Machulka (Scydmaenidae) and Euplectus infirmus Raffray (Pselaphidae) should be removed from the list of Polish species. New records, nomenclature data and correct identification for several other species are given.
