In this paper, I provide the list of the records of Cardiophorus anticus Erichson, 1840 in the Slovakia. The biotopes of this click-beetle species is described in detail and photo-documented. The website photogallery containing 61 photographs of the biotopes serves as a supplement of this paper.

In this paper, I summarize the distribution records of Adrastus circassicus Reitter, 1896 from the Caucasus, Turkey, Czech Republic, and for the first time from Poland. The biotopes of this click-beetle species are described in detail and photo-documented. The website photogallery containing 70 photographs of the biotopes serves as a supplement of this paper. Adrastus juditae Laibner, 1991 is synonymized with Adrastus circassicus Reitter, 1896.

The distribution records of the click-beetles of the subfamily Negastriinae Nakane et Kishii, 1956 of Bečva river (Czech Republic) were reviewed. The following species were included: Fleutiauxellus maritimus (Curtis, 1840), Negastrius pulchellus (Linnaeus, 1761), Zorochros dermestoides (Herbst, 1806), Z. meridionalis (Laporte de Castelnau, 1840), and Z. quadriguttatus (Laporte de Castelnau, 1840). The exact distributional data and the photographs of the biotopes of Negastriinae of Bečva river are added and the biotope conservation management possibilities were briefly discussed.

In this paper, I provide the list of distribution records of Menephilus cylindricus cylindricus (Herbst, 1784) in the Czech Republic and Slovakia.

In this paper, the faunistic records of Ampedus karpathicus (Buysson, 1886) from the Czech Republic and Slovakia are summarized. The biotopes of this click-beetle species are described in detail and photo-documented. The following new synonymy is proposed: Ampedus karpathicus (Buysson, 1886) = Ampedus suecicus Palm, 1976, syn. nov.

The psammo-halophilous species Halammobia bulla Liberto & Leo, 2006 is reported for the first time in Montenegro. The distribution and the differential characters of the two species of genus Halammobia are discussed.

In this paper, the faunistic records of Ampedus brunnicornis Germar, 1844 and A. hjorti (Rye, 1905) from the Czech Republic and Slovakia are summarized. The biotopes of this click-beetle species are described in detail and photo-documented. Ampedus hjorti is for the first time recorded from Romania.

Faunistic information about 773 species of beetles (Coleoptera) is referenced to Protected Landscape Area and Biosphere of Křivoklátsko Reserve (Czech Republic), with 133 species being new additions to a complete beetle catalog of Křivoklátsko Reserve (JANUŠ 2016) and 263 are included on a red list of the Czech Republic (Coleoptera excl. Cantharidae and Byrrhidae: HEJDA et al. 2017; Cantharidae and Byrrhidae: FARKAČ et al. 2005) as endangered species. After the inclusion of new species the total amount of beetle species discovered in Křivoklátsko Reserve has increased to 3460, with only 35 of which were not confirmed since the year 1960. 739 species are included on a red list of the Czech Republic as endangered, which makes it 21,4 % of all currently discovered species of the area. Megasternum immaculatum (Stephens, 1829) (Hydrophilidae) is reported as a new species for Czech Republic. Arthrolips picea (Comolli, 1837) (Corylophidae) is reported from Bohemia for the first time.
