Morphology and Anatomy:

Tylodorinae are characterized by:

• head with oral disc,
• slit-like amphid apertures longitudinally oriented in a lobed or slightly divided labial disc or ring,
• stylet long to very long,
• female reproductive system with more than twenty crustaformeria cells in the uterus and an elongated spermatheca in line (not offset). 
• Phasmids on tail in Tylodorus, ad- or postvulval in the remaining genera.
• Males are known in all the genera, and in almost all the species,
• there is no sexual dimorphism;
• spicules are only slightly curved,
• caudal alae are always well developed. 
• Tails are elongated, with terminus acute to finely rounded.
• Type species of three of the four genera were described from Australia and New Zealand; Tylodorus and Campbellenchus have not been found outside that area.
