Actually, the equator (in this case, it's called the "Girdle of Arda") is much farther south than that. I happen to have an Atlas of Middle Earth, so I can tell you that there is more stuff to the east and south. If you look at the Sea of Rhun, there is a river running into it on one side, but where there should be a river on the eastern side, there's nothing. In The Atlas, there is a river going through there that starts in the Orocarni, which is another mountain range that's slightly longer than the Misty Mountains. In the southern part of the Orocarni, there is a forest called the Wild Wood and another river running south toward the Inner Seas. East of the Orocarni, there is a coastal plain with rivers running toward the East Sea. To the south, there are the Grey Mountains along the coast going south from Umbar. There is a river going east to the Inner Seas and a lot of forests which I take to be jungles in the south. There is also a continent in the southeast called the Dark Land which seems to be covered in jungle and in the far east there is a place that looks a whole lot like a mirror image of Valinor.
