Recorded in the upper part of the North Island, the adult is a 4–6-millimetre-long, thick-waisted wasp with an orange head, prominent black compound eyes, and dark brown or black antennae. They are most commonly found on eucalyptus trees. The larvae excavate the inside of leaves, leaving a blistered and brown papery cuticle. Trees are unlikely to be killed, but may have their growth stunted.
