Xylophanes anubus
A very variable species in terms of size (forewing length 32-58 mm) and degree of development of the oblique lines of the forewing upperside; fresh specimens have a greenish tint that quickly fades to buff-grey. Costal margin of forewing often rather strongly convex and apex recurved so that at rest, the moth has a "rounder", less triangular appearance (similar to Elibia dolichus in outline) that once recognized is characteristic of the species. Abdomen with three dorsal lines; median line usually the most distinct but may be absent, lateral lines sometimes reduced to rows of dots. Spines along posterior margins of posterior tergites uniseriate. Outer spur of midtibia somewhat shorter than inner. Forewing upperside with or without a dark cloud distal to discal cell; seven oblique postmedial lines present of which the third is the heaviest; the lines posteriorly may be more, or less, oblique; the three proximal lines often vestigial or indicated by vein dots; the three distal lines weak or absent, apart from the most distal, which is minimally indicated by strong vein dots. Black area variable in extent so that the pale medial band is often much reduced; pale spots on M1 to M3 usually confluent but occasionally are separate.
Male genitalia: Uncus/gnathos more slender than in Xylophanes ceratomioides. Uncus apically rounded, weakly spatulate, ventrally concave. Gnathos dorsally concave, very weakly sinuate in dorsal view. Harpe curved upwards, basally cylindrical or prismatic, distally irregularly compressed, its sharp upper edge notched and denticulate. Aedeagus characteristic in having a denticulate patch on the left that is not distinctly raised or separated from the body of the aedeagus as a process and a short, dentate, proximally directed process on the right.
