Taxonomia de Microcentrini Brunner Von Wattenwyl, 1878 (Orthoptera: Tettigoniidae: Phaneropterinae)

Abstract

Tettigoniidae (Orthoptera: Ensifera) is a family grouping the insects known as “katydids”.Among the subfamilies of Tettigoniidae, Phaneropterinae is the biggest in the total ofNeotropical species, including katydids that mimic dead or live leaves, generally commonwithin forests. Microcentrini was originally conceived as the group “Microcentra” establishedby Brunner von Wattenwyl, 1878, with 10 Neotropical genera. Then, the group was changedto the new status of tribe by Cadena-Castañeda, 2014. The Microcentrini are characterized bytheir big size, round head, pronotal disc round, tegmina lanceolate or oval similar to a greenleaf, round eyes, male cerci simple with a spine or a round projection on apex, and subgenitalplate big with styli articulate. Currently the tribe includes 11 genera and 81 species. Eventhough it is a very common group to be found in Entomological Collections, there was neverbeen a taxonomic study focused on this group. The objectives in this work were to provide ataxonomic study of Microcentrini; to review and redescribe the genera, including thosepreviously not included in Microcentrini; to describe new genera and species, adding newgeographical records. In this study it was provided the review of Anapolisia; the redescriptionof Acropsis and Raggophyllum; the status revalidation of Tropicophyllumstat. rev.; theredescription of seven species (1 species in Acropsis, 2 species in Anapolisia, 1 species inRaggophyllum, and 3 species in Tropicophyllumstat. rev.); the description of 6 new genera(Boroseiylagen. nov., Caauaragen. nov., Capanemagen. nov., Capiguaragen. nov.,Hyalipennagen. nov. e Tuaiagen. nov.); new combinations in Boroseiylagen. nov.,Anapolisia, and Tropicophyllum stat. rev.; and the description of 50 new species (2 species inAcropsis, 18 species in Anapolisia, 3 species in Boroseiylagen. nov., 9 species in Caauaragen. nov., 2 species in Capanemagen. nov., 2 species in Capiguaragen. nov., 1 species inHyalipennagen. nov., 1 species in Raggophyllum, 10 species in Tropicophyllumstat. rev.and 2 species in Tuaiagen. nov.). It were also provided new dichotomical keys for theidentification of the genera and species, new distribution maps, and comments on thebehavior and natural history.
