Xylophanes letiranti
Similar to Xylophanes crotonis but larger and darker. Antennae more robust than in Xylophanes crotonis. Forewing upperside very dark green or emerald green or brownish with touches of green (the latter form probably being due to deterioration of the green pigment as it is seen only in rubbed or faded specimens); a diffuse black patch present distal to the discal spot, between the costa and first postmedial line, contrasting with the ground colour (in Xylophanes crotonis, this patch, when present, is reduced to two short, thin lines on M2 and M3 distal to the discal spot); all oblique lines heavier than corresponding lines in Xylophanes crotonis; fourth postmedial line enlarged into a dark, diffuse, triangular patch on the inner margin below CuA2, reaching distad as far as the second submarginal line. Oblique black lines on forewing underside straighter and more diffuse than in Xylophanes crotonis. Pale yellow spots forming the median band on the hindwing upperside smaller than in Xylophanes crotonis and speckled with black scales, giving them a more blurred and sombre aspect. Wingspan: 102-112 mm; hence larger than Xylophanes crotonis.
Male genitalia: Uncus broader in dorsal view than in Xylophanes crotonis. Harpe straighter, thinner and less apically upcurved than in Xylophanes crotonis. Phallus with spinose process located subapically (apical in Xylophanes crotonis); left lobe highly reduced, sometimes represented by two or three poorly formed teeth, right lobe also highly reduced, to a small triangular tooth.
