Xylophanes ceratomioides
Antennal flagellomeres with long, fasciculate cilia. Outer spur of midtibia shorter than inner. Abdomen dorsally with three narrow, longitudinal lines; outer lines posteriorly divergent on each tergite and expanded into small triangular spots. Long, narrow, whitish scales gives the upperside of the abdomen a striated appearance (present also in Xylophanes colinae, Xylophanes guianensis, Xylophanes media and Xylophanes xylobotes). Outer margin of forewing slightly scalloped. Base of forewing upperside dark, often almost black but with an off-white patch on the inner edge (of the same colour as pale bands of hindwing upperside); costa with several conspicuous subapical and apical black spots, the largest subapical spot triangular with inner point directed basally; most distal of antemedial lines oblique, running along ventral edge of discal cell as far as CuA1; medial area of the wing running out to the apex pale brown with scattered black scales on the veins, discal spot small, black; oblique postmedial band dark with sinuate black lines within it, inner edge slightly undulate, outer edge deeply excavate from CuA2 to just above M3, forming a pale brown, oval patch; marginal area with black vein spots. Subbasal band of hindwing upperside off-white, divided medially into two patches by a longitudinal black band; width of off-white medial band variable in width and length, sometimes connecting the costal margin and anal patch; sometimes not reaching Rs; the veins crossing it are sometimes all black.
Male genitalia: Uncus gradually narrowed to middle, parallel sided distally; upper surface of distal part evenly convex; ventral surface concave; apex slightly downcurved, with vestige of a sinus. Gnathos obtusely rounded, twice as broad as apical part of uncus; upper surface almost flat, transversely rugose. Harpe narrow, twisted, slightly spatulate, irregularly dentate along dorsal edge. Apical margin of phallus produced on the right side into a very short, denticulate or simple tooth; the left side with a longer, broader, dentate process.
