Superfamily Diplotriaenoidea

Revised 05/28/26

Chromadoria

• The superfamily Diplotriaenoidea is comprised of parasitic nematode species with birds, and eptiles, as definitive hosts and with annelids and arthropods as intermediate hosts
• Feeding sites in definitive host areair sacs, nasal cavities, subcutaneous tissues.

Females in the respiratory system of the definitive host produce smooth, thick-shelled eggs containing a fully developed first-stage juvenile (J1). The eggs pass through the respiratory system into the digestive tract and out via the feces.

 Eggs hatch in the gut of their intermediate hosts (grasshoppers and locusts) and develop to the infective stage.

Families:

• Diplotriaenidae
• Oswaldofilariidae
