Xylophanes chiron subsp. nechus
Diagnostic description:
Very similar to Xylophanes chiron chiron but brown pattern elements of forewing upperside better developed. Moths in which the ground colour is brown rather than green do occur but are very rare. Pale brown scaling along fourth postmedial line more strongly developed, in particular the patch running from M2 to the inner margin is broader and more ovate rather than narrowly triangular.
