“…Therefore, the assignment of P. angrana to Platygonia is doubtful and should be further investigated by means of morphological and molecular phylogenetic analyses. This paper, along with other publications on the taxonomy of the tribes Cicadellini and Proconiini (e.g., Cavichioli & Mejdalani 2012;Silva et al 2017, andPecly et al 2019), reveals that the fauna of the Cicadellinae from the Neotropical Region, especially that from the Amazon Rainforest, is still poorly known. The greater concentration of leafhopper taxonomists in Southeastern and Southern Brazil, in comparison with other regions of the country, is possibly an explanation for this problem, as well as the great difficulties for accessing various collection sites in the Amazon region.…”

A new species of the Neotropical genus Platygonia Melichar, 1925 is described and illustrated from the municipality of Ipixuna, State of Amazonas, Northern Brazil. Platygonia nigra sp. nov. can be distinguished from the other species of the genus by the following combination of features: (1) dark brown to black ground color of dorsum; (2) presence of a white to pale yellow spot at the distal portion of corium; (3) male pygofer with a conspicuous diagonal cleft; (4) connective Y-shaped, keeled, with the stem longer than the arms; and (5) aedeagus with an unpaired basiventral process directed anteriorly. This is the first record of the genus from the Brazilian Amazon Rainforest. Notes on P. undecimmaculata (Fowler, 1899), which is a taxon of uncertain taxonomic position, a key to the species of Platygonia, and a map showing their distribution are added.

“…Genitalia were analyzed and photographed in glycerin, and then stored in micro vials pinned below the specimens. General terminology used in species descriptions follows Deitz (1975) and Sakakibara (2006); genitalia terminology follows Mejdalani (1998), Snodgrass (1993) and Pecly et al (2019); abdominal integument sculpture follows Dietrich (1989). Measurements were made with Image J software version 1.52k.…”

“…Species of Nasuconia are found in lowlands between 60-800 meters altitude. Female terminalia characters are potentially valuable for taxonomy; here we adopt terminology used in Cicadellidae (Mejdalani 1998, Cavichioli & Takiya 2012, Cavichioli & Mejdalani 2015, Pecly et al 2019 due to the lack of recent detailed studies on these structures in Membracidae.…”

The treehopper genus Nasuconia Sakakibara, 2006 previously included four species and was recorded only from Brazil. Here we provide a revised diagnosis of the genus and describe three new species: Nasuconia ellenfutterae sp. nov. from Ecuador, Nasuconia guianensis sp. nov. from French Guiana and Nasuconia yasuni sp. nov. from Ecuador. The genus can be distinguished by the following combination of characters: frontoclypeus conical with transverse grooves, obliquely projected forward at least 1/3 of its length beyond suprantennal margin; pronotum navicular, low, punctate, with longitudinal elevated lines or nodes; first valvulae with ventral interlocking device distinctively sinuate. Two informal species groups are recognized based on characters of the head, forewing and leg chaetotaxy. A key to species, photographs, updated morphological descriptions, and the first descriptions of the female and male genitalia of Nasuconia species are provided. Comparisons of cucullate setae and fine abdominal integument structures are also made using scanning electron microscopy.

The genus Dasmeusa is distributed in Northern and Northeastern Brazil and the Guianas. Until the present study, six species were recognized within Dasmeusa. The species of this genus are very similar in terms of color and external morphology, being distinguished mainly by the male terminalia. Here, we review and redescribe Dasmeusa and its species, describe four new species, and present the first phylogenetic analysis of the genus, including 40 morphological characters and 15 terminal taxa. Dasmeusa flavescens Metcalf and Erythrogonia bicolor Metcalf are considered junior synonyms of the type-species, Dasmeusa pauperata (Fabricius). Scanning electron microscopy was employed for a detailed study of the integument of the type-species, including sensilla, surface sculpturing, brochosomes, organ of Evans, and other structures. The phylogenetic analysis with equal weights resulted in nine most parsimonious trees. The implied weighting method resulted in two trees, both with the same ingroup topology as observed in one of the nine equal-weights trees. This preferred topology is as follows: ((D. basseti (D. mendica (D. rafaelisp. nov., D. falciferasp. nov.))) (D. isabellina (D. oriximinasp. nov. (D. pauperata (D. imperialis, D. dinizisp. nov.))))). Dasmeusa was recovered as monophyletic in all trees, being supported by five apomorphic characters.
