[4] Microcotyle pomatomi was described by Goto in 1899 from the gills of the bluefish Pomatomus saltatrix (Pomatomidae) collected at Newport off Rhode Island, United States.

[3] Williams (1991) compared Microcotyle collected from Pomatomus saltatrix off Western Australia with M. pomotomi, M. australiensis, M. temnodontis and M. debueni from the same host and noted important problems with the parasite taxonomy.

[7] Due to the confusion of the nomenclature surrounding the validity of Caenomicrocotyle-Notasterand Paramicrocotyle, these species were also synonymised with M. pomatomi and retained in the genus Microcotyle until a detailed revision of the Microcotylidae.

The digestive organs include an anterior, terminal mouth, a muscular pharynx, a moderate length oesophagus ending a little behind the genital atriuml pore, and a posterior intestine with two branches provided with numerous lateral diverticula on the inner and outer sides except for the terminal portion of the branche.

It was also reported on the Smooth weakfish Cynoscion leiarchus (Sciaenidae),[10] the deepwater longtail red snapper Etelis coruscans (Lutjanidae),[11] the Striped bass Morone saxatilis (Moronidae),[9] and from the gills of mulloway Argyrosomus japonicus.

[4] Microcotyle pomatomi was recorded off western Australia,[3][8] Egypt,[12] Brazil,[13][14][15][10][16] Japan,[11] Turkey,[17] New York,[9] and off south-western Africa.
