Key to species of Navasoleon Banks

1. Forewing vein Cup+1A reaches hind margin of forewing well beyond radial sector ( Fig. 38 , 40,41); hindlegs and midlegs equal or subequal to length of forelegs; foreleg tarsomere 3 ( Fig. 28 ) less than one half length of distal tarsomere; posterior gonapophysis paddle-like and greatly expanded ( Fig. 55 ), as wide as long; setae brush on foreleg distal tarsomere not hooked ( Fig. 29 ); wings marked (except N. amazonas ) ( Brazil, French Guiana).. (brasiliensis group) 2

— Medial areas of mesoscutellum and metascutellum dark brown ( Fig. 13 ); male genitalia with a large ovoid sclerite between paramere bases ( Fig. 49 ) ( French Guiana)....................................................................... Navasoleon egeri Stange

4. Midtibia swollen ( Fig. 26 ); female terminalia with gonapophysis-like process extending from ventral margin of lateral gonapophysis ( Fig. 62 )................................................................ (tarsalis group) ( Guyana) Navasoleon tarsalis Miller

— Midtibia not swollen ( Fig. 19–25, 27 ); female gonapophysis without gonapophysis-like process extending from lateral margin of lateral gonapophysis ( Fig. 54–61 ).. (leptocerus group) 5

5. Antenna filamentous ( Fig. 37 ); pronotum with all setae no longer than those on clypeus ( Fig. 14, 16 ); foreleg tarsomere 3 70% length of distal tarsomere or less; hindwing with six presectoral crossveins ( Fig. 42, 44 )........................................................ 6

— Antenna clavate ( Fig. 36 ) (antenna of N. bolivianus unknown); pronotum ( Fig. 15–18 ) with many long setae, usually longer than the longest setae on the clypeus; foreleg tarsomere 3 equal to length of distal tarsomere ( Fig. 28 ); hindwing with seven to nine presectoral crossveins (Fig. 39,43,46).................................................................... 7

6. Hindtibia with no setae longer than tibial diameter; pronotum mostly reddish brown with large submedial stripes ( Fig. 14 ); third abdominal tergite darkened with central pale area; (Chaco and Subandean deserts of Argentina)................ Navasoleon leptocerus (Navás)

— Hindtibia with some setae longer than tibial diameter; pronotum ( Fig. 16 ) nearly all pale yellow except lateral margins; third abdominal tergite pale without color pattern; (low cloud forests of northwestern Argentina)............................... Navasoleon lotti Stange

7. Vertex markings ( Fig. 6 ) with anterior dark brown nearly completely dark brown below antennae; anterior half of prothorax with median dark markings ( Peru) Navasoleon lithophilus Miller

— Vertex markings ( Fig. 2, 9 ) with anterior area pale brown, without dark brown area below antennae; anterior half of prothorax all pale............................................... 8

8. Mesoscutellum and metascutellum all pale brown ( Fig. 18 ) ( Venezuela).................................................................. Navasoleon venezolanus Stange

— Mesoscutellum and metascutellum with median dark streaks ( Fig. 11 ) ( Bolivia)............................................................ Navasoleon bolivianus (Banks)
