Abstract

Erythrodiplax nataliae sp. nov. (5 males), collected in Vereda wetlands (a unique Neotropical savanna environment) in Mato Grosso, Brazil is described and illustrated. The new species fits in Borror's Juliana Group, and can be distinguished from other species by the combination of the following traits: blue pruinosity on thorax (more dense dorsally); sides of the pterothorax yellowish, darkening dorsally; face ivory, dorsally black with a metallic blue reflection; wings hyaline with a small basal brown spot; vesica spermalis with long lateral lobes, enclosing the median process and median process elongated with a pair of conspicuous rectangular and elongated lateral lobes, with a middle dorso-ventral furrow.

Highlights

The genus Erythrodiplax Brauer is the most speciose libellulid genus in the New World, currently comprising 58 species distributed from southern Canada to 45° S in Patagonia (Garrison et al 2006, del Palacio & Muzón 2019)
The aim of this work to describe a new species of Erythrodiplax belonging to the Juliana Group from the state of Mato Grosso, Brazil and to provide a modification of the specific key proposed by Borror (1942)
Type specimens are deposited in the following collections: Colección Entomológica Del Museo de La Plata (MLP), Coleção Zoobotânica James Alexander Ratte Laboratório de Entomologia de Nova Xavantina, Universidade do Estado de Mato Grosso (CZNX) and Coleção de Zoologia of the Museu Paraense Emílio Goeldi (MPEG)

Summary

Introduction

The genus Erythrodiplax Brauer is the most speciose libellulid genus in the New World, currently comprising 58 species distributed from southern Canada to 45° S in Patagonia (Garrison et al 2006, del Palacio & Muzón 2019). Borror (1942, 1957) proposed 13 species groups based mainly on the vesica spermalis morphology, including the monotypic Juliana, characterized bythe presence of big lateral lobes in the median process.
