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. The lack of a full generic description has led to significant confusion as to the morphological characteristics that define the genus Dorisiana . Delétang (1919) lists a cruciform elevation notched in the form of a more or less open semicircle and Boulard & Martinelli (1996) list a tapered, triangular timbal cover as characteristic of Dorisiana species.

Diagnosis. S imilar in general appearance to Guyalna but species are distinguished by eyes not extending beyond pronotal lateral edges, triangular timbal covers, timbal cover ventral margin angled dorsally to long body axis rather than being parallel, and lateral lobe of the uncus not extending as far as Guyalna species ( Sanborn 2016a).

Distribution. This genus has been reported over much of the Neotropical region with examples being reported from the Antilles, Argentina, Bolivia, Brazil, Colombia, Costa Rica, Ecuador, French Guiana, Guatemala, Guyana, Mexico, Panama, Paraguay, Peru, Suriname, Trinidad and Tobago, Uruguay, and Venezuela ( Metcalf 1963a; Duffels & van der Laan 1985; Sanborn 2011a, b; 2013; 2014; 2016b; 2018; 2019a; 2020b, d; Sanborn & Heath 2014).
