Review of Nasuconia Sakakibara, 2006 (Hemiptera: Membracidae) with description of three new species.

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 ventralinterlocking 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.

Review of Cyphotes Burmeister, 1835 (Hemiptera: Membracidae) with the description of a related new genus.

The Neotropical treehopper genus Cyphotes Burmeister, 1835 (= Aspona Stal, 1862 syn. nov.) is redefined. Cyphotes contains only two species, the type species Cyphotes nodosa Burmeister, 1835 (= Aspona bullata Stl, 1862 syn. nov.) and Cyphotes quadrinodosa (Fonseca & Diringshofen, 1969) reinstated. comb. Allocyphotes gen. nov. (type species Cyphotes insolita Goding, 1929) is proposed to accommodate two other species previously placed in Cyphotes, Allocyphotes pompanoni (Boulard, 2011) comb. nov. and Allocyphotes colombiensis (Gonzlez-Mozo, 2017) comb. nov., and three new species from Ecuador: A. flavus sp. nov., A. waoraniorum sp. nov and A. robertoi sp. nov. for a total of six species. Illustrations, including genitalia images, new locality records and keys to genera and species are provided.
