Rhabdosynochus is a genus of monopisthocotylean monogeneans, belonging to the family Diplectanidae.Mizelle, J. D., & Blatz, V. (1941). Studies on monogenetic trematodes. VI.

The type-species of the genus, Rhabdosynochus rhabdosynochus Mizelle & Blatz, 1941, was initially described as a member of the sub-family Tetraonchinae. The genus was then transferred to the Diplectaninae by Hargis,Hargis, W.J. Jr. (1955) Monogenetic Trematodes of Gulf of Mexico Fishes. Part III. The Superfamily Gyrodactyloidea (continued). Quarterly journal of the Florida Academy of Sciences, 18, 33–47. then to the Ancyrocephalinae by Bychowsky (1957),Bychowsky, B. E. (1957) Monogenetic Trematodes. Their systematic and phylogeny. Akad. Nauka. USSR. English translation by the American Institute of Biological Science, Washington. 509 pp. and finally to the Diplectanidae by Yamaguti (1963).Yamaguti, S. (1963) Systema Helminthum IV. Monogenea and Aspidocotylea. London-New York, Interscience Publishers. 699 pp. Oliver (1987) confirmed its position within the family Diplectanidae.

Transcriptome The transcriptome of Rhabdosynochus viridisi has been studied in 2022, and G-Protein-Coupled-Receptors (GPCRs) were described in detail in this species, together with those of another monogenean, Scutogyrus longicornis. These were the first two transcriptomes released for monogeneans of the subclass Monopisthocotylea.
