Spheginobaccha is a genus of hoverflies, with 15 known species. ^[1] The genus is readily separated from other microdons by the incomplete metathoracic bridge, round/oval basoflagellomere, occiput with a dorsolateral crease, and other characters. ^[2] It is the only genus in the tribe Spheginobacchini. ^[3]

Biology

Larvae are found in ant nests.

Distribution

They are native to Africa (five species) and Asia (eight species). ^[2]
