In 2010, research on dinosaur ontogeny (growth and development of individuals over the life span) concluded that Torosaurus may not represent a distinct genus at all, but a mature form of Triceratops. However, a subadult specimen and closer analysis of additional Triceratops skulls (as well as several previously overlooked skull differences) led Nicholas R. Longrich and Daniel J. Field to conclude in 2012 the possible synonymy between Triceratops and Torosaurus latus was invalid.
And it wouldn't matter anyway; when it turns out two dinosaurs are one and the same, they always go with the one named first. That's why they went with Apatosaurus instead of the more well-known Brontosaurus name; Apatosaurus was named first. However, Triceratops was named before Torosaurus. Same page:

Also, with the exception of Tyrannosaurus rex, when people talk about dinosaurs, they usually refer to them by genus, not species. (In fact, I believe that Tyrannosaurus rex is the only animal ever to walk the Earth whose species name is both well-known and widely-used - Homo sapiens would come closest to second place, but are more frequently just called "humans" or "people".)
