Xylophanes aristor
Similar to Xylophanes crotonis but immediately distinguishable by the broad grey dorsal stripe on the thorax and abdomen. Most similar to Xylophanes kiefferi but less robust and outer edge of forewing more convex. Differs from Xylophanes crotonis in thorax and abdomen having a broad, grey, dorsal stripe, which is often divided medially by a narrow brown line, and from Xylophanes kiefferi in the olive-green (rather than deep rich brown) upperside of the body. Tegula edged in grey along both its inner (dorsal) and outer (lateral) margins; no median line of grey scales. Forewing upperside similar to Xylophanes kiefferi but ground colour olive-green (rather than deep rich brown) and first and fourth postmedian lines closer together. Forewing underside similar to Xylophanes kiefferi but orange; basal area black and more extensive, so that first postmedian line merges with it around the level of M3; second postmedian line lighter, less sinuate and often comprising a series of discontinuous spots, merging with the dark basal area before CuA2; dark marginal area farther from postmedian area, not reaching the third one (represented by vein dots), dirty grey with a scattering of black scales, very distinct from the ground colour of the rest of the wing and delineated by a grey line that is toothed on M2; apical area, between costa and Rs4 beyond most distal costal dark spot, longer, paler yellow. Anal area of hindwing underside whitish (bright yellow in Xylophanes kiefferi). Aedeagus similar to that of Xylophanes crotonis; left lobe of apical process shorter and broader than in Xylophanes kiefferi, broadly rounded at the end, and with a broader and more rounded serrate flange along the anterior margin; right lobe also shorter than in Xylophanes kiefferi.
