Genus Guyalna Boulard & Martinelli, 1996

Guyalna Boulard & Martinelli 1996: 20 .

TYPE SPECIES.— Fidicina bonaerensis Berg 1879: 140 . ( Argentina)

REMARKS.—The genus was erected as part of a taxonomic key and originally included only two species ( Boulard & Martinelli 1996). A revision of the genus recently published provided a full generic description and reassigned several species into and out of the genus ( Sanborn 2016a). Within the Guyalnina , the species of Guylana can be distinguished by having a combination of the absence of bright green basal area of the fore wings and bright red basal areas of the hind wings, the parallel radial and radiomedial crossveins, a head width as wide as or slightly wider than the mesonotum, without prominent stylate and anteriorly extended eyes and eyes that only slightly project laterally beyond the anterior edges of pronotum, the absence of triangular or curved timbal covers, male opercula that generally form a right triangle, and triangular or small, curved timbal covers. The genus Dorisiana is the most similar to Guyalna but species of Dorisiana can be distinguished by the head being as wide or wider than the mesonotum with eyes not extending beyond the lateral edges of the pronotum, triangular timbal covers, the ventral margin of the timbal cover angled dorsally rather than being parallel to the long body axis, and the lateral lobe of the uncus does not extend to the same lengths in species of Dorisiana as it does in the species of Guyalna ( Sanborn 2016a) .

DISTRIBUTION.—Species of the genus have now been reported from most 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; 2018c; 2019b; 2020a, b; Sanborn & Maes 2012; Maes et al. 2012; Sanborn & Heath 2014; Gogala et al. 2015; Ruschel 2017).
