description: The following key should allow separation of males of Archilestes: 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 <i>Cyptolestes)</i>................................... 2 1'. Marginal cell posterior to subquadrangle in hind wing not greatly enlarged at border, anal border of wing gently convex (Williamson 1921, <i>Fig</i>. 2); broadening ratio 1.20 or less (subgenus Archilestes <i>s.s.)</i>...... 3 2(1). T i p of superior appendage blunt, truncate (Fig. 11; Williamson 1921); Rg arising from R p before third postnodal crossvein in <i>forewing</i>; states of Aragua and Carabobo, Northern Venezuela......... tuberalatus 2'. T i p of superior appendage acute (Figs. 22-24); R3 arising from R2 at <i>or</i>, 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 <b>Rg</b> arising at or before second postnodal crossvein in both wings................................. 5 4(3). Vein <b>Rg</b> arising at or before fourth postnodal crossvein in both wings; pterothorax largely pale with no metallic green stripes; Southern Brazil, Northern Argentina........................................ <i>exoletus</i> 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.. <i>regalis</i> 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................. <i>neblina</i> 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, <i>Fig</i>. 4.62), mesepimeral stripe never metallic; Washington, Oregon, California, Baja California....................... <i>californica</i> 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......... <i>grandis</i>
