''Pseudorhabdosynochus tumeovagina'' is a diplectanid monogenean parasitic on the gills of the Speckled hind, ''Epinephelus drummondhayi''. It has been described by Kritsky, Bakenhaster and Adams in 2015. 〔 〕 ==Description== ''Pseudorhabdosynochus tumeovagina'' is a small monogenean, 0.4-0.7 mm in length. The species has the general characteristics of other species of ''Pseudorhabdosynochus'', with a flat body and a posterior haptor, which is the organ by which the monogenean attaches itself to the gill of is host. The haptor bears two squamodiscs, one ventral and one dorsal. The sclerotized male copulatory organ, or "quadriloculate organ", has the shape of a bean with four internal chambers, as in other species of ''Pseudorhabdosynochus''.〔Kritsky, D. C. & Beverley-Burton, M. 1986: The status of ''Pseudorhabdosynochus'' Yamaguti, 1958, and ''Cycloplectanum'' Oliver, 1968 (Monogenea: Diplectanidae). Proceedings of the Biological Society of Washington, 99, 17-20. (PDF ) 〕 The vagina includes a sclerotized part, which is a complex structure. Kritsky, Bakenhaster & Adams (2015) noted that the species was based on specimens obtained from one of two speckled hind examined for gill parasites and held in the ichthyology collection of the Florida Fish and Wildlife Conservation Commission. The infected speckled hind was collected in 1972 and was not fixed and preserved with its external parasites in mind. As a result, the specimens of ''Pseudorhabdosynochus tumeovagina'' from this fish were in generally poor shape, and many of the internal features, particularly those of the male and female reproductive systems, could not be determined. Nonetheless, the unique vaginal sclerite clearly indicated the species to be new to science.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pseudorhabdosynochus tumeovagina」の詳細全文を読む スポンサード リンク
