Xylophanes aglaor
Most similar to Xylophanes libya but generally darker and more contrastingly patterned, and with a characteristic dark brown inner edge to the tegulae and lunate subapical spot on the forewing underside. Inner margin of tegula dark brown (as in Xylophanes maculator and Xylophanes lichyi). Outer spur of midtibia equal to inner. Forewing upperside as in Xylophanes libya but: ground colour darker; wing covered with scattered black scales; all five postmedian lines (including the doubled first) generally equal in thickness, but sometimes the fourth or the fifth line slightly heavier. Marginal band of forewing underside with basal dark patch more extensive than in Xylophanes libya, Xylophanes loelia and Xylophanes neoptolemus, covering more than half the wing, exceeding the second, and usually the third, postmedian line on the inner margin and often almost reaching the fourth; area between first and fourth postmedian lines yellow, contrasting with the more orange coloration on either side (similar to the condition in Xylophanes neoptolemus but less distinct); black subapical spot on the costa distinctly lunate. Median band of hindwing upperside narrower than in Xylophanes libya, with a consequently broader marginal band. Basal cilia of antennal flagellomeres prolonged. Apical process of aedeagus similar to that of Xylophanes loelia but left lobe with several irregular rows of teeth (as in Xylophanes libya; a single row in Xylophanes loelia).
There is a specimen in NHMUK from Bolivia (Nuflo de Chavez, Esperanza) but it is unclear whether the specimen is mislabelled; it is not mapped.
