Oligophlebia igniflua is a moth of the family Sesiidae. It is only known from the Brisbane district in Queensland, but the distribution of its known host-plant suggests that it will ultimately be found to occur in other rainforest areas in Queensland and the Northern Territory.
The length of the forewings is about 6 mm for males and 6–7 for females.
The larvae tunnel the trunk of the rainforest tree Elaeocarpus grandis. Pupation takes place in the bark.
