Genus Guyalna Boulard & Martinelli, 1996 new record

Guyalna Boulard & Martinelli 1996: 20 .

Type species. Fidicina bonaerensis Berg 1879: 140 . ( Argentina)

Remarks. The genus was erected as part of a taxonomic key ( Boulard & Martinelli 1996) leading to much confusion as to how the taxon should be applied. The first complete description was provided in a recent revision of the genus ( Sanborn 2016a). The absence of bright green fore wing basal areas and bright red hind wing basal areas, head as wide or slightly wider than the mesonotum, lack of prominent stylate eyes extending anteriorly, eyes extending slightly beyond anterior pronotal angle, parallel fore wing radial and radiomedial crossveins, male opercula roughly forming a right triangle, and timbal covers with rounded anterior apex and ventral margin parallel to long body axis distinguish species of Guyalna from other Guyalnina . The most similar genus to Guyalna is Dorisiana but species of Guyalna can be distinguished by a head as wide or wider than the mesonotum, eyes extending slightly beyond lateral pronotal edges, timbal covers with rounded apex, timbal cover ventral margin parallel to long body axis, and lateral lobe of uncus extending further than found in species of Dorisiana ( Sanborn 2016a) .

Distribution. Species of the genus are found over much of the Neotropics including references to Argentina, Bolivia, Brazil, Colombia, Costa Rica, Ecuador, French Guiana, Guyana, Nicaragua, Panama, Paraguay, Peru, Uruguay, and Venezuela ( Metcalf 1963a; Duffels & van der Laan 1985; Boulard & Martinelli 2011; Sanborn 2011a, b; 2013; 2014a; 2016a, b; 2018b; 2019b; 2020a, c, d; Sanborn & Maes 2012; Maes et al. 2012; Sanborn & Heath 2014; Gogala et al. 2015; Ruschel 2017) with a recent expansion of the range to include Trinidad ( Sanborn 2020e).
