Male terminalia of Cercopidae (Hemiptera, Cicadomorpha): towards a consensus terminology

Abstract The study of male genital appendages is often necessary to identify a species and to characterise the higher systematics ranks for the Cercopidae, a large family of Hemiptera. Therefore, many authors have used them in their work but without any clear consensus on the terms used for each par...
