Ambulyx canescens
Greyer than Ambulyx moorei, a species with which it shares the presence of a pair of ocellate marks subapically on the abdomen instead of a narrow line dorsally. Ambulyx canescens also bears stronger subbasal markings on the forewing and a stronger green edging to the thorax. Forewing upperside ground colour greyish; discal spot distinctive; subbasal marking distinctive, although resembling that in Ambulyx moorei . Hindwing upperside colouring broadly the same as in the forewing; bearing distinctive pale patches.
Male genitalia: Tergum A8 deeply sinuate mesally; edge of tergum very oblique. Uncus longer than in other species of Ambulyx, broad and incised at apex; curved slightly in lateral view. Gnathos triangular and sharply pointed in ventral view. Harpe distinctive, connected with body of valva only at base; very long and slightly twisted; apical third suddenly narrows and bent dorsally. Phallus with concave, toothed, apparently moveable apical process; ventrally with patch of denticles.
Female genitalia: Tergum A8 long, truncated, not emarginated. Sterigma with pair of curved at each side of ostium bursae.
