Abstract

Stridulation is the most common method of sound production in Coleoptera, with approximately 17 types recognized across more than 30 families. In this study, two types of ventrite-femoral stridulatory systems are identified and described within the subtribe Hylobiina, distinct from those known in Coleoptera and other Curculionidae. System type 1 is associated with the genus Heilus Kuschel 1955, while system type 2 is found in a group of species within the genus Heilipodus Kuschel 1955. The species Heilus spinipennis comb. nov., is transferred from Heilipodus to present system type 1. Finally, the differences in the ventrite-femoral stridulatory system known for various taxa of Curculionidae are discussed.
