Diagnosis. According to Malicky (2013), D. obscura ( Ulmer 1930) is a synonym of D. aurovittata . These two species are very similar. No wing patterns are visible (perhaps because our specimens are preserved in alcohol). However, differences exist that distinguish these species ( Malicky 2002). Variants for this species also exist ( Malicky 2002), but we infer that illustrated variations depend on the orientation of a specimen as drawings or photographs are prepared. For example, in dorsal view ( Fig. 22 ), the left lateral lobe of tergum X is very similar to that of the type of D. aurovittata , but the right lateral lobe appears smaller because it was drawn by rolling the genitalia slightly. Differences are clear and obvious. The differences include the following: In D. aurovittata the mesocaudal lobes of tergum X are directed dorsad in lateral view and the lateral (outer) edges of the lateral lobes of tergum X are pointed in dorsal view; whereas in D. obscura the mesocaudal lobes of tergum X are directed posterad in lateral view, and the lateral (outer) edges of the lateral lobes of tergum X are rounded in dorsal view.
