Enyo gorgon (Cramer, 1777)

Forewing apex sinuate in both sexes. One of the four species of Enyo with a forewing androconial organ in the males.Costal margin of forewing convex before middle due to the strong development of the androconial organ; androconial organ very broad, distally delimited by the crossveins, which are distorted from the normal sphingid configuration: m1-m2 twice the length of m2-m3, running distad, m1-m2 and m2-m3 forming a right angle that is open proximally, m2-m3 running an obtuse angle with m3-cu1a, M2 arising from angle of m1-m2 /m2-m3, curved backwards near its base.Hindwing crossvein m3-cu1a more than half the length of m2-m3. Antenna imperceptibly incrassate distally, hook long.Crest of thorax very high. Forewing upperside dichromatic, anterior half pale brown, posterior half medium brown, the border delimited by a dark brown longitudinal line, the posterior margin of which is poorly defined and which diverges apically to form a dark brown triangular patch before the marginal pale brown half-moon shaped patch. Hindwing upperside brown, anterior half with a pale brown marginal band. Forewing upperside basal of antemedian line and distal to the antemedian line below CuA1, and half-moon shaped patch on outer margin below apex pale brown, contrasting strongly with the rest of the wing; surrounding the discal spot is a dark brown patch, which is abruptly contracted at CuA2 into a narrow line that extends along the antemedian line to the posterior margin; distal edge of the dark brown patch merging gradually into a medium brown area delimited distally by the half-moon shaped marginal patch and posteriorly by CuA2. Uncus similar to Enyo lugubris lugubris but apical process much shorter, ventral processes stouter and not so close together.Valve ending in a long, strongly sclerotized, slender process; dorsal margin strongly convex distally, apical hair scales longer than valve.Aedeagus with an indication of the triangular process found in Enyo cavifer.
