Archilestes, Garrison, 1982

The following key should allow separation of males of Archilestes View in CoL :

1. Marginal cell posterior to subtriangle in hindwing enlarged at border so that anal border of wing is strongly convex ( Williamson 1921, Fig. 1; Donnelly 1981, Figs. 3, 5). Broadening ratio (length of distal vein of marginal cell posterior to subtriangle in hind wing relative to that of forewing) 1.23 or more (subgenus Cyptolestes )................................... 2

1'. Marginal cell posterior to subquadrangle in hind wing not greatly enlarged at border, anal border of wing gently convex ( Williamson 1921, Fig. 2); broadening ratio 1.20 or less (subgenus Archilestes View in CoL s.s.)...... 3

2(1). T i p of superior appendage blunt, truncate ( Fig. 11 View Figures 10-24 ; Williamson 1921); Rg arising from R p before third postnodal crossvein in forewing; states of Aragua and Carabobo, Northern Venezuela ......... tuberalatus

2'. T i p of superior appendage acute ( Figs. 22-24 View Figures 10-24 ); R3 arising from R2 at or, more often, beyond third postnodal crossvein in forewing; southern Mexico to Costa Rica.................................. latialatus

3(1'). Vein Rg arising from R2 beyond second postnodal crossvein in both fore- and hind wings .......... 4

3'. Vein Rg arising at or before second postnodal crossvein in both wings ................................. 5

4(3). Vein Rg arising at or before fourth postnodal crossvein in both wings; pterothorax largely pale with no metallic green stripes; Southern Brazil, Northern Argentina ........................................ exoletus View in CoL

4'. Vein Rg arising from R2before fourth postnodal crossvein in both wings; pterothorax with broad stripe of metallic green on mesepimeron and mesepisternum ( Gloyd 1944, Fig. 1); Northeastern Mexico.. regalis View in CoL

5(3). Posterior half of superior appendages greatly expanded, truncate and leaf-like in appearance (Figs. 7, 9); large species, abdomen excluding appendages 55 mm, hind wing 42 mm; Costa Rica ................. neblina View in CoL

5'. Posterior half of superior appendages linear, similar in width to basal half of appendages (Pritchard and Smith" 1956, Fig. 4.62); smaller species, abdomen excluding appendages less than 50 mm, hind wing less than 40 mm ................................... 6

6(5). Inferior a b d o m i n a l appendages parallel-sided (Pritchard and Smith 1956, Fig. 4.62), mesepimeral stripe never metallic; Washington, Oregon, California, Baja California ....................... californica

6'. Inferior abdominal appendages divergent, not parallelsided (Pritchard and Smith 1956, Fig. 4.62); dark mesepimeral stripe often metallic green; United States south to Colombia and Venezuela......... grandis View in CoL
