About Xylophanes titana Druce, 1878
Xylophanes titana, first described by Druce in 1878, has a wingspan ranging from 60 to 88 mm. It is similar in appearance to Xylophanes eumedon. The tegula features a golden medial line. On the upperside of its abdomen, there are two narrow pale lines, which are divided down the middle by a sharp, broad olive-green or brown line that is much wider than the pale lines. On the prothorax, the two pale lines merge into a single median line. On the underside of the forewing, the apical area along the costa is the same pale yellow color as the area between the second and fourth postmedian lines. The median band on the upperside of the hindwing has distinct pale yellow spots; smaller apical spots are often reduced in size and suffused with black. This species has been recorded from Mexico, Belize, Guatemala, Honduras, Nicaragua, Costa Rica, Panama, Colombia, Ecuador, Peru, Bolivia, Paraguay, Argentina, Venezuela, French Guiana, and Brazil, and it is thought to also occur in Guyana and Suriname.
