The wingspan is about 96 mm. It is similar in colour and pattern to Manduca lichenea, but the hindwing upperside is more extensively grey, with a patch posterior to the discal cell extending to the more proximal of the median dark bands. Furthermore, the transverse lines on the forewing upperside are more prominent.
Adults are on wing in November and February.
