Panogena lingens

Panogena lingens is a moth of the family Sphingidae. It is known from Madagascar and the Comoro Islands.
It is similar, but much darker than "Panogena jasmini". The abdomen has yellow lateral patches. The hindwing upperside is black at the extreme base.
The long-spurred "Neobathiea grandidierana" from Madagascar is pollinated by the long-tongued hawkmoth with the pollinaria deposited on the basal part of the proboscis of the moth.
