Similiar species:
Very similiar to Deilephila elpenor macromera found in the eastern Himalaya (Nepal and eastwards)

"but more muted in colour, the khaki areas being dull olive-green and the pink areas less bright and more buff." Kitching, I. Sphingidae Taxonomic Inventory.

"pink on the underside far more evenly disposed over the disk of both wings than in the eastern form macromera." Hampson, 1892.

"Like P. e. macromera, but the rosy-red parts of body and wings shaded over with cinnamon, being far less bright than in macromera, especially on the wings." Bell & Scott, 1937. 

Deilephila elpenor seems to lack white spots on the abdominal segments, which are quite prominent in many individuals of D. rivularis (less prominent in some individuals). The use of this feature for separation of these two species needs verification by examining a wide range of museum specimens (pers. comm. Ian Kitching).

Notes on species: Individuals from Munsiari and Jhala in Uttarakhand were incorrectly identified as D. elpenor but are actually D. rivularis.(pers. comm. Ian Kitching). This was rectified on 7 July 2021. There are no confirmed records of D. elpenor from W. Himalayas (Kashmir, Himachal Pradesh and Uttarakhand).
