Novo gênero para Edessinae (Hemiptera, Heteroptera, Pentatomidae) com sete espécies novas

Abstract

Edessinae, belonging to the family Pentatomidae, is considered monophyletic and is distinguished by its remarkable morphological variation. With approximately 500 species organized into 17 genera, Edessinae is the second most diverse and numerous subfamily of Pentatomidae. Currently, Edessinae is being subjected to various taxonomic revisions and adjustments aimed at organizing and clarifying this complex group. Due to its significant morphological variation, the subfamily faces numerous challenges related to taxonomy and nomenclature. Thus, the objective of this study was to describe a new genus composed of seven new species. With the aid of a stereomicroscope, the structures of the body, including the head, thorax, abdomen, female genitalia, and especially the male genitalia, were described. Illustrations and a map of the geographic distribution are presented. This genus is characterized by having a flat metasternal process, narrow with the anterior bifurcation margin evanescent and the apex acuminate; short pygophore with shallow floor presenting an expansion that embraces the base of the parameres; simple, reddish or orange parameres, curved dorsoposteriorly; distal part swollen in posterior view; expanded black lateral margins. This work aims to contribute to the knowledge of Edessinae diversity, enriching the understanding and taxonomic classification of this group. Species recognition is extremely important to improve knowledge about the taxon and diversity of the Neotropical region.
