Latoplana levis

Latoplana levis (Hyman, 1953) Mexistylochus levis Hyman, 1953a: 293–294, fig. 27 (type locality: Puerto Peñasco, Sonora, Mexico). Ommatoplana levis – Hyman 1955a: 72 (new combination); 1955b: 9 (description). — Brusca 1980: 70, fig. 4.3 (identification keys); 2005: 70 (checklist). Latoplana levis – Faubel 1983: 64 (new combination). Distribution Puerto Peñasco, Sonora, Mexico. Habitat Benthic. 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.
