Hampe, 1863) and Chennium siculum Fiori, 1914, were collected in Sicily and three species, Panaphantus atomus Kiesenwetter, 1858, Bibloplectus pusillus (Denny, 1825), and Bibloplectus delhermi (Guillebeau, 1888), are recorded for the first time from Calabria.

    ABSTRACT
    So far, special attention to the endogean and MSS (Mesovoid Shallow Substratum) fauna was not paid in Bulgaria, though typical subterranean species of the Coleoptera have been described. The aim of present study is to put on record the results of a broad-scale study of the coleopteran fauna from the MSS and lower (euedaphic) soil horizons in the country. We carried out investigations in the period April 2006–July 2014, manly in the Vitosha Mt., Pirin Mt., Stara Planina Mts., Slavyanka Mt., Belasitsa Mt., Erma and Kresna Gorge, Western Rhodopes Mts., and Srednagora Mts. For the time being, material from the following families was identified to the genus and species levels: Anobiidae, Aphodiidae, Carabidae, Clambidae, Corylophidae, Curculionidae, Endomychidae, Histeridae, Leiodidae, Monotomidae, Scyrtidae, Silvanidae, Silphidae, Staphylinidae (Pselaphinae) and Zopheridae. We report for the first time the subgenus Antisphodrus Schaufuss, 1865 (Carabidae) and Zustalestus Reitter, 1912 (Curculionidae) from Bulgaria. Blemus discus discus (Fabricius, 1792) is recorded for the second time from the country.
