Scientific classification
Domain:	Eukaryota
Kingdom:	Animalia
Phylum:	Platyhelminthes
Class:	Monogenea
Order:	Mazocraeidea
Family:	Microcotylidae
Subfamily:	Microcotylinae
Genus:	Diplostamenides; Unnithan, 1971

Diplostamenides is a genus which belongs to the family Microcotylidae and class Monogenea. As all Monogenea, species of Atriostella are ectoparasites that affect their host by attaching themselves as larvae on the gills of the fish and grow into adult stage. This larval stage is called oncomiracidium, and is characterized as free swimming and ciliated.

Members of the genus Diplostamenides are characterised by a genital atrium armed with a corona of graded spines and relatively few, usually much stouter spines on head of the penis.^[1]
