Remarks

Latoplana levis was originally described by Hyman (1953a) within the genus Mexistylochus Hyman, 1953 . Hyman (1955a) later transferred it to the genus Ommatoplana Laidlaw, 1903, and finally, Faubel (1983) transferred the species to the genus Latoplana . The genus is characterized by a prostatic vesicle lined with a ray-shaped or digitiform epithelium. A revision of the morphology of the reproductive system of L. levis is suggested because some of the characters described (prostatic vesicle and Lang’s vesicle) are similar to those described in the genus Latocestus .
