Xylophanes alvarezsierrai Alvarez Corral, 2002

Similar to Xylophanes tersa tersa but smaller, forewing ground colour dark brown and hindwing median spots orange-red. Outer line of tegula greyish (white in Xylophanes tersa tersa); golden median stripe absent. Lateral golden stripes on abdomen with fewer dark rays than Xylophanes tersa tersa. Forewing upperside as Xylophanes tersa tersa but ground colour darker brown, obscuring many of the pattern elements; pale area between third and fourth postmedian lines conspicuous; fourth and fifth postmedian lines, and submarginal lines weakly visible against slightly lighter distal part of the wing. Spots of median line of hindwing upperside less sharply defined and separated than in Xylophanes tersa tersa, orange-red in colour (more reddish towards the apex and more yellow towards the anal angle); marginal band dark brown. 28 mm (so smaller than average Xylophanes tersa tersa). Appear to be identical to those of Xylophanes tersa tersa.
