Ambulyx liturata
Distinguished from Ambulyx maculifera by the absence of a sub-basal costal patch on the forewing upperside, although occasionally a longitudinal dash is present instead; the medial line of the abdomen upperside does not become dilated into a patch on abdominal tergum A8 of the male. Differs from Ambulyx substrigilis by having the base of the hindwing upperside less tawny and never black and by the submarginal line of the forewing being more proximal posteriorly. Although some females are as pale as the male, others are more deeply tinted and have a more distinct violet-grey gloss on the forewing.
Male genitalia: Abdominal sternum A8 convex mesally and with margin thickened. Gnathos similar to that of Ambulyx placida, more deeply sinuate than in Ambulyx substrigilis. Harpe with an almost vertical submesal process at distal end of submesal ridge; distal process very broad, spoon-shaped. Phallus with two dentate folds of unequal length; dorsally wall extended into a short obtuse process.
Female genitalia: Abdominal tergum A8 membranous mesally so that sclerite is deeply incised. Sterigma surrounding very large ostium bursae; proximal part membranous; edge of ostium raised to a folded ridge; distal part of sterigma rounded, transversely multicarinate
