Remarks. Metcalf (1963a) synonymized a number of species in his catalogue but there may be several valid species in the list. For example, D. metcalfi was shown to have distinct genitalia from D. semilata and was removed from synonymy ( Sanborn & Heath 2014). The relatively short descriptions of Walker (1850) may mean that more of these synonymized species will turn out to be valid taxa and be resurrected eventually.

Dorisiana semilata is another species with a greenish tawny head and thorax and an ochraceous abdomen. It can be distinguished from D. metcalfi by the wider mesothorax (usually more than 10 mm wide), the transverse piceous fascia on the anterior abdominal tergites, a large piceous spot on the dorsal opening of the timbal cavity formed by tergites 1 and 2, the infuscation in the distal fore wing basal cell, the posterolateral angle on the female operculum margin, the male operculum not extending to sternite II with the posterior margin mainly transverse with a medial anterior curvature and an almost right angle on the posterolateral corner, female sternite VII is sinusoidal with the lateral arch extending beyond the posterior of the notch, the slightly sinuate posterior margin of female abdominal segment 9, and the primary femoral spine is angled to the femoral axis found in D. semilata .

Distribution. The species has been reported across a wide geographic range. Records for the species have been published for Argentina, Bolivia, Brazil, Colombia, Costa Rica, French Guiana, Guyana, Paraguay, Suriname, St. Lucia, the Antilles, Trinidad, 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 (Sanborn 2018c), Peru ( Sanborn 2020c), and Ecuador ( Sanborn 2020d) are in error. The range might be refined significantly if some of the synonyms turn out to be valid species.
