Remarks: This species, originally described from Muzo, Colombia, has masqueraded under the name Argia cuprea as indicated in the synonymy above. Garrison & von Ellenrieder (2017) provided illustrations and keys for the separation of the metallic species of Argia known from Mexico and Central America. They restricted the name Argia cuprea to specimens occurring from Southern Texas south through Honduras noting that cuprea -like males from Costa Rica and Panama were of a different species based on appendage and genital ligula morphology. These latter specimens matched the type of Argia fulgida (see below) that was described from Colombia and was subsequently included with material from Ecuador west of the Andes except for overall abdominal color. Their study thus suggested the presence of two largely allopatric forms of Argia fulgida , a cuprea -like morph from Central America ( Costa Rica, Panama) and a largely oenea -like morph from Colombia and Ecuador west of the Andes; no significant morphological differences in the male genital ligula and caudal appendages or in the female mesostigmal plates were detected. A few, cuprea -like morphs (Manabí Prov., Palmar; Pichincha Prov., road to Silanche Bird Sanctuary) of A. fulgida have also been found among populations of the more numerous populations of oenea -like morph in Ecuador but they appear to be infrequent.

Heckman (2008) (following Garrison unpublished) and Garrison et al. (2010) listed A. fulgida as a junior synonym of A. cupraurea Calvert since Navás' description seemed to suggest that species. However, differences in the morphology of the genital ligula and appendages as shown by Garrison & von Ellenrieder (2017) showed them to be distinct. Determination of just what Argia fulgida represents has not been an easy problem to solve. Navás provided no illustration and it is unclear whether he had just one male (holotype) or more than one at his disposal. His description is also suspect since he reverses the number of postnodal crossveins in the fore and hind wings. We ( Garrison & von Ellenrieder 2015) have pointed out that some of Navás' descriptions pertaining to Argia should be used with caution since he apparently included two different species in his description of A. stigmatica ( Navás 1934) , and he also described as Argia damselflies from different genera (and in one case, a different family). Some of his descriptions and accompanying illustrations when compared to type material can be confusing (see under A. medullaris below). Navás' description of A. fulgida largely corresponds to the specimen we have considered as lectotype although the postnodal counts (18 in Fw, 16 in Hw) do not match those given in the original description (16 in Fw, 12 in Hw [Note: these numbers were originally reversed, "12 postnodalibus in ala anteriore, 16 in posteriore.") but the overall length (41 mm) and abdominal length (32.5 mm) do. Unless contrary evidence suggests otherwise, we are accepting Legrand's designation of the male, which we illustrate here, as lectotype of the name. Diagnosis of A. fulgida is given under A. philipi .
