2. Abdominal tergites 3–5 fasciate, anterior 1/2–2/3 of tergites brown to brassy, frequently subshiny, contrasted distinctly with dull colored bluish gray or greenish gray posterior margins..................................................... 3
– Abdominal tergites 3–5 not fasciate with brown anterior bands which contrast with bluish gray to greenish gray posterior mar- gins; if slightly fasciate, anterior band concolorous with posterior margin although coloration frequently more intense or shin- ier.................................................................................................. 5

4. Surstylus in lateral view tapered gradually to apex (Fig. 73); surstylus in posterior view long, gradually widened at base, lack- ing distinct lateral protrusions basally; epandrium in posterior view wider, with lateral margins more or less straight, not dis- tinctly sinuate...................................................................... N. chilensis (Macquart)
- Surstylus in lateral view distinctly curved at nearly a right angle subapically; surstylus in posterior view short and with broadly produced lateral protrusions basally; lateral margins of epandrium narrow, sinuate, pedunculate in posterior view...............................................................................................

5. Dorsum of thorax and abdomen brassy to metallic greenish blue; abdomen more bluish posteriorly; surstylus in lateral view with subapical enlargement before recurved apex...................................... N. ciligena (Rondani) in part
- Dorsum of thorax and abdomen greenish brown to brassy, abdomen more greenish brown posteriorly; surstylus in lateral view more or less gradually and evenly tapered to apex, posterior margin gently arched..................... N. caesia (Wulp)
6. Gena high, about 1/2 eye height; setae generally larger and more abundant........................................ 7
- Gena shorter, generally 1/3–1/4 eye height; setae weaker and less abundant........................................ 8
7. Legs entirely dark colored, more or less concolorous............................................. N. lenti (Oliveira)

- Lateral surstylar process shorter, length from base 1/3 or less length of surstylus in lateral view....................... 15
11. Coloration of anepisternum, especially toward posterodorsal corner, distinctly darker than whitish gray katepisternum..... 1 2
- Coloration of anepisternum and katepisternum more or less concolorous, if anepisternum much darker than color changes very gradual............................................................................................. 13
12. Surstylus in lateral view over twice as long as wide (width not including lateral prong); posteroventral margin of surstylus evenly curved subapically (Argentina, Brazil, Chile).................................. N. pravoneura (Hendel) in part
- Surstylus in lateral view less than twice as long as wide (width not including lateral prong); posteroventral margin of surstylus shallowly recurved subapically, appearing slightly sinuate......................................... N. inca sp. nov.
13. Anepisternum and katepisternum mostly olivaceous brown.................................................... 14
- Anepisternum and katepisternum mostly gray to grayish brown (Bolivia)................. N. pravoneura (Hendel) in part
14. Surstylus in lateral view tapered evenly and gradually to apex; lateral surstylar prongs in posterior view distinctly protrudent................................................................................. N. prionoptera (Thomson)
- Surstylus in lateral view with subapical swelling before abruptly rounded apex; lateral surstylar prongs curving inward, not protrudent in posterior view....................................................... N. ciligena (Rondani) in part
15. Anepisternum and katepisternum mostly concolorous, gray; surstyli in posterior view broadly produced to bluntly-rounded apex................................................................................... N. penai sp. nov.
- Anepisternum generally darker than grayish katepisternum, if more or less concolorous, both brown; surstyli in posterior view narrowed distinctly to acutely-pointed apex................................................................ 16
