Dorisiana metcalfi Sanborn & Heath, 2014

Cicada viridis Olivier 1790: 754 . (Suriname)

Dorisiana metcalfi Sanborn & Heath 2014 nom. nov. pro Cicada viridis Olivier, 1790 nec Cicada viridis Linnaeus, 1758: 60 .

Remarks. Metcalf (1952; 1963a) and many other authors considered a large number of species to be synonyms of Dorisiana semilata (Walker, 1850) . Included in this list of species is what is now D. metcalfi . However, there are distinct genitalia and other morphological characteristics represented by Cicada viridis Olivier, 1790 from those of D. semilata so Sanborn & Heath (2014) provided a replacement name for the taxon represented by C. viridis . A number of specimens from across Suriname (the type locality of C. viridis) are required in order to determine definitively if D. metcalfi and D. semilata are synonyms and the current concept of D. metcalfi represents a third taxon. Dorisiana metcalfi is a species with a green head and thorax lightly marked with piceous and a tawny abdomen. The green can fade or be chemically altered to tawny. It can be distinguished from D. semilata by the narrower mesothorax (usually less than 9 mm wide), the lack of transverse piceous fascia on the anterior abdominal tergites, a small piceous mark on the dorsal opening of the timbal cavity formed by tergites 1 and 2, the lack of infuscation in the distal fore wing basal cell, the smoothly curved posterolateral female operculum margin, the male operculum extending to sternite II with the posterior margin angled anteromedially forming a more acute angle on the posterolateral corner, female sternite VII is slightly waved with the lateral extension about the same distance as the posterior of the notch, and the large semicircular posterior extension of female abdominal segment 9, and the primary femoral spine is adpressed to the femur in D. metcalfi .

Distribution. The species has been reported from Argentina, Bolivia, Brazil, Colombia, Ecuador, Paraguay, Peru, Suriname, and Venezuela (Metcalf 1963a; Dorval et al. 2011; Sanborn 2011b; 2013; 2019b; 2020c, d; SantosCividanes et al. 2013; Sanborn & Heath 2014; Dias et al. 2017). Previous records to Panama are in error (Sanborn 2018b).
