Differentiation in the ultrastructure of pectiniform antennae in species groups of the genus Ctenoceratoda Varga, 1992 (Lepidoptera, Noctuidae)

Abstract

We studied the types of sensilla on the pectinated antennae of Ctenoceratoda species (Noctuinae, Hadenini) using scanning electron microscopy. These ultrastructures are described, illustrated and analysed in four distinct species groups of the genus. The group features distinguishing the four lineages of the genus and their taxonomic importance are discussed.
