Members of the Prochaetosominae have general characteristics of the family
Draconematidae

- Pharynx largely cylindrical with terminal bulb well defined or weakly
developed (e.g. Dracogalerus, Notochaetosoma); medium
swelling of corpus present in Dracognomus.
- Swollen anterior body region usually marked
- Helmet present (except in Dinetia).
- Cephalic adhesion tubes with or without swollen base at insertion and
with or without open tip; located on helmet or posterior to helmet.
