Explanation of Names
Probably named after the pattern on the abdomen.

Note-there is also an undescribed species of Zelia that resembles vertebrata, known from Kentucky (O'Hara & Stireman, 2016) and Pennsylvania. Some photos placed in vertebrata may be this species.
Most of United States, southern Canada, Mexico
Parasitoid of beetles (like most Dexiini)
