Description
Members of the genus Tragocerus are diagnosed by having filiform antennae, slightly shorter than the body. The elytra are long and form a rectangle. They are fused along the mid-dorsal line, though each elytron has indentations just above the wing's point of origin, allowing it to move without meaningful disruption.Nicholson, A. J. 1927. [https://ia601009.us.archive.org/3/items/biostor-245808/biostor-245808.pdf Presidential Address: A New Theory of Mimicry in Insects]. The Australian Zoologist. 5: 10–104 Tragocerus species appear to mimic wasps; while convincing in flight, their sluggish movements upon landing betray their identity.
