The head is similar to that of Recent Gomphidae with two large and globular compound eyes that are distinctly separated, but closer together than in damselflies (Zygoptera).
There are also two cephalic sutures.


The pterothorax seems to be even more strongly skewed than in damselflies.
The legs are extremely long with short and strong spines, and with very elongate tarsi.
There are three tarsal segments (tarsomeres), of which the most basal one is twice as long as the others.
The pair of tarsal claws lack the ventro-apical hook of modern odonates.
