Xylophanes resta
Intermediate in appearance between Xylophanes aristor and Xylophanes tersa. Outer spur of midtibia longer than inner. Tegula with a weakly developed golden medial line. Upperside of thorax with a grey medial band, bordered laterally and divided medially by brown lines, which is continued along the abdomen but becoming faint after first two abdominal segments. Golden-yellow lateral stripes on abdominal segments 3 to 6 more distinct than in Xylophanes tersa, with a patch of pale hairs and black patch anterior to it. Abdominal sternites without distinct lines. Forewing somewhat broader than Xylophanes tersa. FWL: 36-41 mm. Forewing upperside with a characteristic brown tone; first postmedial line very strong basally but disappearing towards the apex; second postmedial line fused basally with the first (as in Xylophanes eumedon); fourth postmedial line less than half the width of the first. Hindwing upperside with pale yellow spots of medial band larger than in Xylophanes tersa, the more distal closer to the margin; all separate apart from those from CuA2 to 2A; small marginal spot at anal angle. Forewing (and hindwing) underside brighter than in Xylophanes tersa, the brown markings consequently more prominent; a straight brown line, in some places indistinct, crossing the wing parallel to distal margin, crossing M3 about 1.5-2 mm from discal cell; marginal area not, or only slightly, darker than disc; a weakly defined yellow costal patch present apically (similar to that in Xylophanes titana). Marginal area of hindwing underside divided by the veins, which are pale orange.
Male genitalia: Uncus sinuate, subcarinate above, as in Xylophanes tersa. Gnathos broader than in Xylophanes tersa. Harpe tapered to a point, upcurved near tip. Phallus more similar to Xylophanes crotonis than Xylophanes tersa; right lobe of apical process with a short right-sided marginal tooth, left lobe with a dentate, somewhat hand-shaped process.
