Hummingbird clearwing moth

I've based my ID on the description of the hummingbird clearwing (Hemaris thysbe): "Adult: forewing clear area has partial crossband of dark scales near base, and distal margin of clear area is uneven or ragged-edged (not smooth-edged); legs pale/whitish (vs. reddish in gracilis and black in diffinis). Underside mostly white in front, extending to front legs, then reddish behind, unlike mostly black underside of H. diffinis."
