Revisão taxonômica de Dorisiana METCALF, 1952 (Hemiptera, Auchenorrhyncha, Cicadidae, Cicadinae, Fidicinini)

Abstract

The members of Cicadidae are insects popularly known as cicadas, easily recognized in your environment because of male singing. Cicadoidea is currently divided into Tettigarctidae and Cicadidae, and this into three subfamilies: Cicadinae, Cicadettinae and Tibicininae. Cicadinae has many neotropical tribes, Fidicinini, one of the most representative, is divided into Fidicinina and Guyalnina and has 16 genera. Into Fidicinina, Fidicina and Fidicinoides are the ones with highest number of described species and none of the other genera of the tribe has a taxomic revision, being absent publications that establish characters to distinguish them. Into Guyalnina, Dorisiana has economic importance as pest of coffee and also taxonomic problems, besides the lack of morphological characters needed for its determination, which is increased by the lack of a review covering all genera present in the tribe. The general goal of this work was execute the taxonomic revision of Dorisiana species improving the knowledge about the taxon, with the specific objective to analyze the morphology of the genus from deposited specimens of collections of national and international institutions; describe the morphological species, including photographs and ilustrations, mostly of the male genitalia; produce a pictorial dichotomous key to distinguish the Dorisiana species. Therefore, of the 16 species of the genus, previously known, four were synonymized, two new combinations and two new species were described, totaling 16 valid species, covered in the pictorial dichotomous key.From these results and studies that led to it, is perceived a great lack of group by works that delimit characters needed for your determination, for genus and species, which is also shared by others neotropical tribes. Starting of these assumptions suggested in the future more studies on characters for a cladistics analysis of the Dorisiana species and the continuity of the studies with the members of the tribe to establish reliable characters in recognition of evolutionary lineages.
