Genus Desmatoneura
Desmatoneura argentifrons
Whether all of the handful of known records represent the same taxon is somewhat debatable. Specimens have been taken at puddles southeast of the Picacho Mtns and with some regularity in the Sulphur Springs Valley. The species also takes nectar at the tiny flowers of various species of Euphorbia. Most specimens are between 5 and 7 mm long. While the males' wings are hyaline, females often show some pale coloration in the wings. In Hull (1973), the venation drawing is mislabeled and actually pertains to Fig. 380 rather than Fig. 379.
Range: COCH, PIMA, PNAL
