(Syn. Astiotrema magniovum Fischthal & Kuntz, 1965 )

Record. 1. Fischthal & Kuntz (1965).

Remarks. Plesioastiotrema magniovum n. comb. is similar to P. monticellii in most morphological characters except in having (i) roughly equally-sized suckers, (ii) more longitudinally-extended vitellarium distributed from a little anterior to the ovary to the level of the posterior margin of the anterior testis, (iii) longer ceca that terminate at the level of the end of the posterior testes, (iv) large, distinct, transversely elongated testes, (v) a submedian genital pore located at the anterosinistral margin of the ventral sucker and (iv) larger eggs (62–76 × 28–35 µm vs 22–31 × 11–14 [see Dollfus 1957]).
