Rozšíření nosatců rodu Hypera (Coleoptera: Curculionidae) na území České republiky

Abstrakt: Faunistic data on weevils of the genus Hypera Germar, 1817 from the Czech Republic, obtained from literature and 61 private and museum collections, are given. Twenty-four species are currently known from the Czech Republic. Distribution of all species is commented. First exact data on the occurrence of Hypera arundinis (Paykull, 1792) in the Czech Republic are presented. H. cumana (Petri, 1901) is recorded for the first time from the Czech Republic. A single old Moravian record of H. constans (Boheman, 1834) was probably based on misidentified specimens of H. cumana. H. striata (Boheman, 1834) is recorded from Moravia for the second time. The following ambiguous faunistic data are discussed: the possible first records of H. fornicata (Penecke, 1928) from the Czech Republic, and of H. ononidis (Chevrolat, 1863) and H. striata from Bohemia. Hypera libanotidis (Reitter, 1896) was collected only in two or possibly three Moravian localities and is now probably globally extinct. New observations on larval development are described for H. nigrirostris (Fabricius, 1775) and H. plantaginis (De Geer, 1775): larvae of H. nigrirostris feed inside unripe flowers of Trifolium repens. Larvae of H. plantaginis develop on Anthyllis, Coronilla, Lotus and Oxytropis of Fabaceae, not on Plantago of Plantaginaceae, where they only build the cocoon and pupate.
