David Král, Oliver Hillert
Three new species of Lethrus (Lethrus) Scopoli, 1777 from the Balkan Peninsula are described: L. (L.) halkidikiensis sp. nov. (Greece: Halkidiki Peninsula), L. (L.) perun sp. nov. (SW Bulgaria) and L. (L.) strymonensis sp. nov. (N Greece: region Séres). They are closely related to L. (L.) raymondi Reitter, 1890. Diagnostic characters (shape of mandibles and shape of ventral mandibular process) are illustrated. The character matrix for the separation of males of the Lethrus species closely related to L. raymondi known from Bulgaria, Macedonia and NW Greece and a map of the distribution areas for each species are presented.
