After this publication, the list of known barkfly species in the country contains a total of 67 species. A checklist is provided with references to the original records. Keywords: Balkans, barkflies, distribution Introduction Results The insects from the order Psocoptera are very poorly Philotarsidae studied in Bulgaria. Till the author began working on barkflies, only 29 species had been registered in the Philotarsus parviceps Roesler, 1954 country (Popov 1939, 1961, Drensky, 1953, Lienhard 1998, Giese, 1964, Grigorov, 1975, Meinander, 1978, Material examined: 6.8.2020, Rila Mountains, Bo- Lienhard & Smithers, 2002, Tomov & Trencheva, rovets Resort, pine forest dominated by Picea abies, 2013, Sziráki 2013).
