Hydnobius punctulatus Hampe, 1861 (Coleoptera: Leiodidae): Redescription of species, comments on variability and new distributional data for Central Europe

The type specimens of Hydnobius punctulatus Hampe, 1861 were examined, redescribed and illustrated. Lectotype as well as paralectotypes were fixed by inference. The species is characterised by the form of the aedeagus with sinuate parameres and by the wide and pale antennal club. Variability is commented on basis of additional material collected in Slovakia. Records from Slovakia represent the northernmost distribution in Central Europe. Examination of other material revealed a new record of Hydnobius claviger Strand, 1943 for Slovakia.
