REMARKS.—The number of species that were synonymized by Metcalf (1963a) may not all represent the same species. For example, D. metcalfi was erected out of synonymy after it was shown the genitalia of the species differed ( Sanborn & Heath 2014). The relatively short descriptions in Walker (1850) may mean that some of the synonymized species are in fact valid taxa.

The references to D. semilata in Ecuador are all as synonymized examples of D. metcalfi in Metcalf’s (1963a) catalogue. No specimens have been seen or reported in the literature as D. semilata in Ecuador. As a result, D. semilata is removed from the cicada fauna of Ecuador.

DISTRIBUTION.—The species has been reported from a wide geographic range. Records for the species have been published for Argentina, Bolivia, Brazil, Colombia, Costa Rica, French Guiana, Guyana, Paraguay, Peru, Suriname, St. Lucia, the Antilles, Trinidad & Tobago, Uruguay, and Venezuela ( Metcalf 1963a; Duffels & van der Laan 1985; Dorval et al. 2011; Sanborn 2011a, b; 2013; 2014a; 2019b; 2020b, e; Sanborn & Heath 2014). Previous records to Panama are in error ( Sanborn 2018c) as are the Ecuadorian records. The range may be refined significantly if some of the synonyms turn out to be valid species.
