Allopseudaxine macrova is a species of monogenean flatworm, which is parasitic on the gills of a marine fish.

[2] Allopseudaxine macrova was described from the gills of the Kawakawa Euthynnus affinis off India, as Uraxine chura maacrova.

The haptor is delimited from the body by a constriction and bears a single row of clamps.

The digestive organs include an anterior mouth, a pharynx, an oesophagus and a posterior intestine that bifurcates at or near level of genital pore in two lateral branches.

The reproductive organs include an anterior genital atrium armed with a corona of 17 hooks, two unarmed vaginal pores, with sub marginal dorsal longitudinal slit like apertures, situated behind the penis on each side of the body but not at the same level, a looped ovary and numerous testes para and post-ovarian.
