Guyalna Boulard & Martinelli 1996

Genus Guyalna Boulard & Martinelli, 1996 new record Guyalna Boulard & Martinelli 1996: 20. Type species. Fidicina bonaerensis Berg 1879: 140. (Argentina) Remarks. The genus was revised recently and a full generic description was provided (Sanborn 2016a). Diagnosis. Within the Guyalnina, species of Guylana are distinguished by having a combination the absence of bright green fore wing basal areas and bright red hind wing basal areas, parallel radial and radiomedial crossveins, head as wide as or slightly wider than mesonotum, head without prominent stylate and anteriorly extended eyes, eyes slightly projecting laterally beyond pronotum anterior edges, triangular or curved timbal covers absent, timbal covers with rounded anterior margin and ventral margin parallel to long body axis, and male opercula generally forming a right triangle. Dorisiana is most similar to Guyalna but species of Dorisiana can be distinguished by eyes not extending beyond pronotum lateral edges, triangular timbal covers, ventral timbal cover margin angled dorsally rather than parallel to long body axis, and lateral uncus lobe not extending to as far as species of Dorisiana as it does in the species of Guyalna (Sanborn 2016a). Distribution. With the continuing increase in species diversity within the genus, there are now records from most of the Neotropical region. Species have been reported from 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; 2014; 2016a, b; 2018; 2019a; 2020a, b, d, e; Sanborn & Maes 2012; Maes et al. 2012; Sanborn & Heath 2014; Gogala et al. 2015; Ruschel 2017).
