Genus Dorisiana Metcalf, 1952 Dorisia Delétang 1919: 83. Dorisiana Metcalf 1952 nom. nov. pro Dorisia Delétang, 1919 nec Dorisia Möschler, 1883: 351. TYPE SPECIES. Cicada semilata Walker 1850: 122. (St. Lucia, Antilles and Cayenne, French Guiana) REMARKS. There has been significant confusion as to the characteristics that define Dorisiana. The problems began with the genus being introduced as part of a taxonomic key (Delétang 1919) and neither Metcalf (1952) with the replacement name nor Boulard & Martinelli (1996) provided a full description of the genus when they separated Dorisiana and Guyalna by two characters in a key when Guyalna was introduced. The lack of a full generic description has led to multiple species being assigned to incorrect genera or species being reassigned to different genera only to be reassigned again in the future. Delétang (1919) lists a cruciform elevation notched in the form of a more or less open semicircle while Boulard and Martinelli (1996) list a tapered, triangular timbal cover as characteristic of Dorisiana. Dorisiana is most similar to Guyalna but species 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, ventral margin of the timbal cover angled dorsally not parallel to the long body axis, and the lateral branch of the uncus does not extend to the same lengths as the species of Guyalna (Sanborn 2016a). DISTRIBUTION. The genus has been reported over much of the New World with examples being recorded from the Antilles, Argentina, Bolivia, Brazil, Colombia, Costa Rica, Ecuador, French Guiana, Guatemala, Guyana, Mexico, Panama, Paraguay, Peru, Suriname, Trinidad & Tobago, Uruguay, and Venezuela (Metcalf 1963a; Duffels & van der Laan 1985; Boulard & Martinelli 2011; Sanborn 2011a; 2011b; 2013; 2014a; 2016b; 2018c; Sanborn & Heath 2014).
