          Abstract

          Die Fähigkeit zur Lauterzeugung ist unter den Käfern weit verbreitet. Von den 3 bei Käfern entwickelten Verfahren zur Geräuschproduktion, dem Ausstoßen von Gasen (Bombardierkäfer), dem Klopfen eines Körperteils auf das Substrat (Totenuhr) und dem Aneinanderreiben zweier Körperteile, der Stridulation, ist letztere am weitaus häufigsten vertreten. Die Zahl stridulierender Arten ist jedoch ebenso wie der Bau und die Lage des Stridulationsapparates in den einzelnen Familien sehr unterschiedlich [Dudich 1921, 1922, Meixner 1934]. Während etwa in der Familia Cerambycidae Vertreter fast aller Genera einen Lautapparat haben, gibt es bei den Silphidae nur 2 stridulierende Genera: Ptomascopus Kraatz 1876, eine rezent nur in Asien beheimatete Gattung, und die vor allem in der nördlichen Hemisphäre verbreitete Gattung Necrophorus Fabricius 1775.

          Translated abstract

          (a) Contrary to former belief, burying beetles of the genus Necrophorus Fabricius 1775 use only 1 of the 2 files of their stridulatory apparatus during stridulation. (b) The stridulatory apparatus of the 10 Central European species of Necrophorus can be classified into 4 main types according to the general structural pattern of the pars stridens. (c) Morphological detail analysis of the stridulatory apparatus using 12 parameters supplies little evidence on sex-specification. However, in some cases species-specification is clearly evident. (d) Sonagrams show that even the sounds produced by closely related species can be species-specific although their stridulatory apparatuses are very similar. Also, the same stridulatory apparatus is capable of producing quite different sounds used for intraspecific communication depending on the biological situation. (e) Comparison of the sounds produced by 5 Necrophorus species shows that protest sounds (in all probability sent to warn potential predators) are quite similar. Contrarily, the spontaneously produced sounds (preceding the copula or when feeding the larvae) appear to be clearly species-specific.
