Allopseudaxine macrova

The body of Allopseudaxine macrova comprises an anterior part which contains most organs, and a posterior part called the haptor. The haptor is delimited from the body by a constriction and bears a single row of clamps. The clamps of the haptor attach the animal to the gill of the fish. A short terminal lappet is present, and is armed with two pairs of hooks. There are also two buccal suckers at the anterior extremity. 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. Each adult contains male and female reproductive organs. 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. The eggs are spindle-shaped, with filaments at both poles.^[1]

The type-host is the Kawakawa Euthynnus affinis (Scombridae). The type locality is off India.^[1]
