SANTOS1 and NILZA M. MartinELLI2 Abstract: The objective of this study was to describe and illustrate the morphological characteristics of some species of Brazilian Fidicinoides to aid in their identification. Descriptions and illustrations are given of the head, thorax, abdo- men, right forewing and the last urosternite of the male of the Fidicinoides besti, Fidicinoides brunnea, Fidicinoides duckensis, Fidicinoides pseudethelae and Fidicinoides sucinalae species. The main diagnostic characteristics of these species are markings on pronotum and/or mesonotum and male sternite VIII characteristics. Key words: Cicadoidea. Cicadas. Fidicinini. Morphology. Taxonomy. Resumen: El trabajo tuvo como objetivo estudiar la morfologia de algunas especies del género Fidicinoides e ilustrar rasgos que permitan su reconocimiento. Se presentan descripciones e ilustraciones de la cabeza, el tórax, el abdomen, la parte anterior del ala derecha y el último urosternito del macho de Fidicinoides besti, Fidicinoides brunnea, Fidicinoi- des duckensis, Fidicinoides pseudethelae y Fidicinoides sucinalae. Los principales caracteres de diagnóstico de estas especies son marcas registradas del pronoto o mesonoto y caracteres del VIII urosternito del macho. Palabras clave: Cicadoidea. Chicharra. Fidicinini. Morfología. Taxonomía.
