The first reliable records of Larinus vulpes (Olivier, 1807) (Coleoptera: Curculionidae: Lixinae: Lixini) from Central Europe and Hungary are presented. The species has been found in several locations of the Kiskunság National Park and adjacent areas, on the known host plant Echinops ritro subsp. ruthenicus (M. Bieb.) Nym. (Asteraceae).

Records of 24 Curculionoidea species new for the Biebrza Basin in Northeastern Poland, including the Biebrza National Park and its buffer zone, are provided as a result of field studies in 2021-2022. Three more weevil species, unique or rare in Poland, were rediscovered in the Biebrza Basin after nearly 20 years, including Anthonomus rubripes GYLLENHAL previously thought to be extinct. The fauna of the Biebrza Basin comprises currently 505 species of Curculionoidea (Scolytinae excluded), being among the richest documented for protected areas in Northeastern Poland. Noteworthy and alarming is a great decrease in abundance of practically all hygrophilous weevil species observed in the Lower Biebrza, compared to results of previous surveys conducted in 1999-2004.

This paper follows the first part of the annotated checklist of weevils (Coleoptera: Curculionoidea excepting Scolytinae and Platypodinae; ‘exSP’ below) of the Czech Republic and Slovakia, published by Benedikt et al. in 2010. The introductory chapter presents a new checklist following the current system and nomenclature of Curculionoidea (Alonso-Zarazaga et al. 2017a), and excluding species of improbable or impossible occurrence in the Czech Republic and Slovakia. The main chapters of the paper include comments on species of the subfamily Brentidae: Apioninae and several subfamilies of Curculionidae: Cossoninae, Entiminae, Lixinae, Mesoptiliinae and Molytinae, that are interesting from faunistic, ecological or other points of view. Besides supplementary comments, faunistic revision of some species included in the first part of the annotated checklist are presented. At present, we recognise the reliably documented occurrence of 846 species of Curculionoidea (exSP) in Bohemia and 931 species in Moravia. In total, 970 species are reliably known from the Czech Republic. For Slovakia, 1056 species are reliably documented and in total, from the whole territory of the Czech Republic and Slovakia (former Czechoslovakia) there are presently 1109 reliably documented species of Curculionoidea (exSP). The paper also brings some faunistical changes: the recent occurrence of Nanophyes globiformis Kiesenwetter, 1864 is confirmed for Bohemia and Phyllobius xanthocnemus Kiesenwetter, 1852 is reported as a new species for Bohemia. The occurrence of Mecinus heydenii Wencker, 1866 and the recent occurrence of Bruchela conformis (Gyllenhal, 1833) are confirmed in Moravia and Dieckmaniellus gracilis (L. Redtenbacher, 1847) is reliably documented for the territory of the Czech Republic.

Lachnaeus crinitus (Boheman, 1836) is recorded from Bohemia for the first time. Celiodinus nigritarsis (Hartmann, 1895) is a new species for Moravia. Possible occurrences of Nanophyes globulus (Germar, 1821), Pelenomus olssoni (Israelson, 1972) and Neoplinthus tigratus porculus (Fabricius, 1801) in Moravia are confirmed. Bionomic notes on the weevil species are also presented.

From May, 17 th to 24 th the weevil fauna of several localities in the surrounding area of Stúrovo (southern Slovakia) was investigated. 12 sites were visited by all participants. Despite a rather good level of previous knowledge, the species lists for all sites could be improved considerably. The total number of the recorded species is 360 and includes the families Anthribidae (6 species), Apionidae (48), Attelabidae (1), Curculionidae (292), Dryophthoridae (1), Nanophyidae (4), Erirhinidae (1) and Rhynchitidae (7). There were two sites with a speciose Ceutorhynchinae and one site with a speciose Tychius fauna. Important species of the sites are highlighted, and the most important species of all searched sites are commented on separately. In many cases host plant relations were also recorded, but although there was a targeted search effort, the host plant of Hypera cumana remains unknown.

The first part of the annotated checklist summarizes the present knowledge on the distribution of the superfamily Curculionoidea except for Scolytinae and Platypodinae (below exSP) in the Czech Republic – divided into the historical lands Bohemia and Moravia, and Slovakia. It evaluates the present as well as historical occurrence of each species on these territories. In addition, bioindicator status and several other characteristics (endemicity, allochthonous species, new records for the territory) are given. In selected sections, systematic background, faunistics, historical research on the Curculionoidea families in the Czech Republic and Slovakia, and the species composition of the Czech and Slovak weevil faunas, its postglacial progress and a short characterisation of some selected important areas are given. These evaluations are based on specimens available in the collections of Czech and Slovak institutions as well as private collections and records from hundreds of historical publications. The first part also contains comments on species that are interesting from faunistic, ecological or other points of view. Comments on species of the families Anthribidae, Rhynchitidae, Attelabidae, Nanophyidae, Brachyceridae, Dryopthoridae, Erirhinidae and several subfamilies of Curculionidae: Curculioninae, Bagoinae, Baridinae, Ceutorhynchinae, Conoderinae and Hyperinae are included in this part. Comments on the family Apionidae and the remaining subfamilies of Curculionidae will be presented in subsequent parts of the publication. At present, we consider the occurence of 817 species of the Curculionoidea (exSP) in Bohemia as reliably documented; the presence of another 51 species requires confirmation. 35 species mentioned in historical publications we exclude from the Bohemian fauna of Curculionoidea (exSP). We reliably know of 903 species of Curculionoidea (exSP) from Moravia, with another 53 species requiring confirmation and 59 previously published species excluded. Together 950 species are reliably known from the Czech Republic and the occurence of another 42 species requires confirmation. 68 species published in the past are excluded from the list of Curculionoidea (exSP) of the Czech Republic. For Slovakia, 1036 species are reliably documented and a further 48 species require confirmation. We have excluded 76 species published in the past as a part of the Curculionoidea (exSP) fauna of Slovakia. Altogether, from the whole territory of the Czech Republic and Slovakia (former Czechoslovak Republic) there are 1091 species of Curculionoidea (exSP) reliably documented, 37 species that require additional confirmation, and 102 species from historical publications are excluded from the Curculionoidea (exSP) fauna of this territory. Our paper adds 13 species for the first time to the Curculionoidea fauna of the Czech Republic, of which 5 species were found in Bohemia: Brachysomus hispidus (L. Redtenbacher, 1849), Hexarthrum duplicatum Folwaczny, 1966, Magdalis caucasica (Tournier, 1872), Nanophyes globiformis Kiesenwetter, 1864 and Otiorhynchus rugosus krattereri Boheman, 1843 and 9 species were found in Moravia: Anthribus scapularis Gebler, 1833, Donus viennensis (Herbst, 1795), Gonotropis gibbosa Le Conte, 1876, Gymnetron tibiellum Desbrochers, 1899, Lixus fasciculatus Boheman, 1836, Nanophyes globiformis Kiesenwetter, 1864, Otiorhynchus brunneus Krynicki, 1834, Sitona callosa Gyllenhal, 1834 and Tropiphorus micans Boheman, 1842. In addition 8 weevil species are new only for Bohemia: Ceutorhynchus merkli Korotyaev, 2000, Cleopomiarus micros (Germar, 1821), Curculio elephas (Gyllenhal, 1836), Donus oxalis (Herbst, 1795), Gasterocercus depressirostris (Fabricius, 1792), Ixapion variegatum (Wencker, 1864), Omphalapion buddebergi (Bedel, 1887) and Omphalapion pseudodispar Wanat, 1995 and 9 weevil species are new only for Moravia: Dorytomus reussi Formánek, 1908, Isochnus angustifrons (West, 1916), Mogulones venedicus (Weise, 1879), Onyxacalles croaticus (H. Brisout, 1867), Otiorhynchus armadillo (Rossi, 1792), Pelenomus olssoni (Israelson, 1972), Sibinia variata (Gyllenhal, 1836), Trichosirocalus rufulus (Dufour, 1851) and Tychius sharpi Tournier, 1873. We also report 16 weevil species not previously published from Slovakia: Brachysomus fremuthi Koštál, 1991, Brachysomus tenuicollis Yunakov, 2006, Ceratapion beckeri (Desbrochers, 1875), Ceutorhynchus hutchinsiae Tempère, 1975, Ceutorhynchus fallax Boheman, 1845, Ceutorhynchus merkli Korotyaev, 2000, Lixus lateralis (Panzer, 1793), Miarus simplex Solari, 1947, Omphalapion pseudodispar Wanat, 1995, Orchestes stobieckii Smreczyński, 1957, Otiorhynchus dacicus J.
