Xylophanes alvarezsierrai

Xylophanes alvarezsierrai is a moth of the family Sphingidae. It is known from western Venezuela.

The length of the forewings is about 28 mm. It is similar to Xylophanes tersa tersa but smaller, the forewing ground colour is dark brown, the hindwing median spots are orange-red and the lateral golden stripes on the abdomen have fewer dark rays. The forewing upperside ground colour is dark brown, obscuring many of the pattern elements. The spots of the median line of the hindwing upperside are less sharply defined and separated and orange-red in colour. The marginal band is dark brown.
