Banyutus lethalis is an African antlion.

It is proposed as the mimic for the gregarious African antlion, Hagenomyia tristis, but can be identified based on the longer antennae and a bicoloured pterostigma.

Both species fly gregariously through long grass and can be collected together.

The larvae of B. lethalis are non-pit building, whereas those of H. tristis are pit-builders.
