Agamomermis is a collective group for immature Mermis-like worms, which 

 have not developed to a stage permitting a definite generic determination. 

 Such a group has no type species. 



Agamonema Diesing, 1851a, 78, 116-122. A collective group for immature nematodes 

 in fish, and as such it has no type species. Original species:
