Eumorpha obliquus
Most similar to Eumorpha anchemolus but: forewing shorter, broader, with an even outer margin; forewing upperside a strong contrast between the generally light basal half and the generally dark apical half; abdomen lacking a clearly defined dorsal stripe. Generally darker than Eumorpha guadelupensis and Eumorpha orientis; underside of body yellowish, as in Eumorpha orientis, rather than rosy as in Eumorpha guadelupensis. Labial palp segment 1 with white spot narrower and longer than in Eumorpha anchemolus. Conspicuous white line behind eye. Underside of body and wings yellowish. Foretibia with outer surface grey. Forewing upperside more glossy grey than in Eumorpha anchemolus; three oblique parallel lines present in basal area running straight from costal margin to CuP fold; discal spot absent; oblique shadowy band broad extending to outer margin, where it is broader than in Eumorpha anchemolus; subapical costal patch large; dark patch near tornus broader than in similar species of Eumorpha, rounded triangular, not concave distally, extending anterior to CuA2, but here not narrowed; fringe of posterior margin buff, less extensive than Eumorpha anchemolus.
Male genitalia: Uncus rounded-truncate, apex longitudinally ribbed. Valve slender, dorsal margin slightly concave from base to apex, no patch of bristles on inner face. Harpe similar to Eumorpha satellitia but shorter and less curved. Phallus apical process short and obtuse.
