About Plagioneurus univittatus Loew, 1857
Plagioneurus is a genus of long-legged flies that belongs to the family Dolichopodidae. This genus contains only a single species, Plagioneurus univittatus, and Plagioneurus itself is the only genus in the subfamily Plagioneurinae. The distribution of Plagioneurus univittatus ranges from the eastern United States, southward through to South America. The genus name comes from two Ancient Greek words: πλάγιος (plágios), meaning 'oblique', and νεῦρον (neûron), meaning 'nerve'. This name refers to the unusual angle of the final section of the medial wing vein M, which converges with the radial vein R4+5. In adult Plagioneurus univittatus, the thorax is metallic green with a prominent black stripe running down its center. The abdomen is black, with white pruinose bands along its posterior edges. The wings of this species are hyaline.
