Lintneria praelongus is a moth of the family Sphingidae.
It is known from Honduras and Guatemala.[1]
It is similar to Lintneria istar but more greyish white and the forewings are more elongate.
The larvae probably feed on Lamiaceae (such as Salvia, Mentha, Monarda and Hyptis), Hydrophylloideae (such as Wigandia) and Verbenaceae species (such as Verbena and Lantana).
